Adding a second battery
When Lightning Energy installed our Powerwall 2 back in December 2023 it was great. Paired with our 13 kW Enphase/Jinko solar system and 10 kW inverter, it's been handling our fully electrified home in Emerald pretty well — five reverse-cycle ACs, heat pump hot water, EV charging, and grid outages lasting up to nine days. But as we've added more loads, I've been thinking about expanding battery storage. There was a problem, though. The Powerwall 2 is no longer CEC-approved for new installations in Australia. Tesla stopped taking orders for it in late 2024/early 2025, and as of January 2026 it's no longer on the Clean Energy Council approved list. So you can't add a second one. And until very recently, the Powerwall 3 — Tesla's current model — was completely incompatible with the Powerwall 2. They couldn't talk to each other. That meant anyone with a Powerwall 2 who wanted more storage faced a painful choice: rip out the existing battery and start fresh with new hardware. For me, that…

First Tesla service call: a new wheel
First service call for our Tesla Model Y. Replacing our loaner wheel with a new wheel. As you can see in our posts from a few weeks ago, we hit a pothole, damaging our left rear wheel. At the time, we only knew that we had a slow leak. We logged the problem in the Tesla app. They arranged for roadside assistance to come to us, in about an hour, to install a loaner wheel, and take ours away to diagnose. Today, Tesla replaced the loan wheel with a new wheel, costing a whopping $1319. I asked them to clean the damaged wheel and put it in the back of the car. In the photos, you can see the buckle and crack. I am wondering if it is fixable. When I booked this service in the app, I also asked them to fix the water in the light bar, and some issues with the steering wheel buttons. They replaced both. I’ll discuss the steering wheel buttons in a separate post. All covered under warranty. I had a bit of trouble figuring out where to leave the car. Several after me also mistakenly parked in…

Bonang Road brought back my motorcycle days
Harkening back to my motorcycle days, enjoying the endless curves along the Bonang Road from Tubbut to Orbost, Victoria, leaving the Snowy Mountains. The Tesla handled the drive beautifully. FSD off, for some driving fun. I had to watch out for quite a few sharp dips, barely marked with crayon width paint on the road. This road has stopping spaces specifically for motorcycles (pictured). Yesterday, I grabbed some groceries in Bombala and noticed the "Welcomes Motorcyclists" sign. Before we bought our first EV in 2022, we did a lot of motorcycle road trips. As you can see from the photos from a decade ago, we haven't aged at all! 😉. I'd love to see some "Welcomes EVs" signs in regional places. My stay last night in Tubbut was thanks, in part, to the simple EV changer provided by Gippsland Climate Change Network. They are on to something!

Creekside car camping in the Snowy Mountains
Car camping in my Tesla, beside a creek, off the beaten track in the Snowy Mountains. It took me a while to find the site. Earlier, in my search, I pulled off onto two tracks that ended up in someone’s property. At least it gave some local kids an excuse to run outside to see what the UFO sound was I did a three point just outside their gate. I waved and grinned. A cup of tea and a snack from my Teraglide drawer, sitting in my camp chair, watching the bush life. Until the bush life started eating me (just a few bugs), signaling time for bed. I again wished I had remembered to pack a collapsible stool, to help climb into the back of the car. Followed by the commando crawl to get on top of the Snuuzu mattress and Teraglide platform. This is the highest sleeping option, which gives lots of storage space and a very comfortable bed. The only down side is requiring more effort getting in and out. Once I’m in, it’s great with plenty of room to move. Please forgive the “Tesla Tripping – after…

The best rest stop in the middle of nowhere
Wow, possibly the best amenities for a road trip, at this spot in the middle of nowhere (in the Snowy Mountains). Seats and tables, beautiful location, playground, water, toilets, WiFi. Even has a shower and laundry tubs. Oh, and a pizza oven. Hard to beat! Gotta love the various signs on the amenities (see photos). Thanks to Gippsland Climate Change Network and Chargefox for the destination EV charger here. It’s probably the only public fuel source (of and kind) for over 100km. There are no shops or food outlets here. Fortunately, I grabbed some supplies when passing through Bombala and Cooma, over the past few days. Instant kitchen: pop the Tesla tailgate, pull out the Teraglide drawer and table, flip up the lid to reveal the fridge in the sub trunk. After a couple of hours to eat and chill, off to find a campsite for the night, nearby along the river. I’ll come back in the morning to use the shower.

No petrol in Dalgety, but plenty of power points
No petrol, no worries. The small town of Dalgety has no working petrol station. The last working bowser I passed yesterday was about 50km away in Cooma, along with the nearest fast EV charger. But Dalgety does have hundreds of power points, including the powered camp sites at Snowy River Holiday Park. I could have used any one of them to fill up my car. It’s a beautiful spot. I car camped there last night. This morning, I pushed the Teraglide kitchen drawer back in, pressed the Deflate button on my Snuuzu mattress, flipped back the top (pictured), and moved the drivers seat back into my preferred position by hitting the Restore button in the Tesla. Super quick transformation, ready to drive on to the next camp site today.

Breakfast routine, Tesla-style
Good morning! Time for breakfast, after a great night’s sleep in the Tesla. “Siri, open Tesla boot”. The tailgate opens to reveal a beautiful day, beyond my bare feet. Breakfast mode: 1. Pull out the Teraglide drawer and table. 2. Flip open the Teraglide rear lid. It’s assisted by gas struts, so it’s easy to lift and stays up, even with bedding on top of it. 3. Open the fridge in the subtrunk to get brekky supplies. This morning, that’s eggs, butter and milk. 4. Use the kitchen drawer bits to crack and whisk the eggs, add milk, soak some bread, ready to make French toast. 5. Stroll over to the camp kitchen. Fry the toast and boil some water for my thermos. Return to the Tesla. Enjoy my French toast, with a cuppa tea, overlooking the Snowy River. Nice.

Photo op in Bredbo, campsite hunt in Cooma
Photo op in Bredbo, before stopping in Cooma to figure out where to camp tonight. On the way, I used the Tesla’s navigation to search for “campground” and similar. One option was The NRMA park in Jindabyne. I tapped the phone icon, to make a call. Handy to do it all from the car’s controls. Unfortunately, all their powered and unpowered sites were booked for tonight. This looked like a job for WikiCamps. Since Tesla doesn’t support Apple CarPlay, I needed to pull over to use my phone. Whenever parking, I aim to charge, so I don’t lose any time. So, I pulled into the new-ish Tesla Superchargers in Cooma. This is the second site in Cooma, with more chargers and faster speed. But the only service nearby seemed to be KFC (again 🤔). No matter, I just wanted time to access my phone. Snowy River Holiday Park looks great. I rang them, gave them my ETA, entered it into the navigation, added Cooma Coles as the first destination, so I could grab some supplies. Cooma Coles also has Tesla…

Dinner next to the Snowy River. I grabbed soup and butter from the fridge in the sub trunk. Heated the soup and toasted bread at the camp kitchen. Enjoyed the simple meal as the sun set, listening to the river. Happy place. My 35L Kings fridge is in the sub trunk. It’s powered by the car’s 16V supply, with an outlet available in the boot and driver’s console. The 16V in turn is powered by the car’s massive 60kWh battery. No need to run an engine, with noise and fumes, to keep it going.

Setting up the Teraglide bed in the Model Y
Setting up the Teraglide platform and Snuuzu mattress in the Tesla Model Y. Steps: 1. Folded back seats down, using the buttons in the Tesla. 2. Slid the interleaved top of the Teraglide platform onto the folded down rear seats. 3. Moved the front seats forward. 4. Unfolded the top hinged bit of the Teraglide. 5. Clipped on the side supports of the Terglide, near the doors. 6. Placed the Snuuzu mattress bag on the Teraglide platform. 7. Unzipped the bag, unrolled the Snuuzu mattress. Unclipped the mattress and opened it up flat. 8. Pressed the `Inflate` button on the mattress. Waited a minute for it to finish, then turned it off. 9. Added bed linen, blanket and pillow. Gotchas: 1. Teraglide (the business) had warned me, after seeing earlier photos of my installation a few months ago, that I had neglected to strap down the front of the Teraglide. With this in mind, I brought along the supplied straps, but I hadn’t yet installed them. When I fully extended the kitchen drawer without…

Lunch stop at Oliver's, just outside Gundagai. I recommend the Oli burger 🍔. Tesla Model 3 with stripes parked near us. FSD along most of the Hume Highway. It does a great job, and avoids human fatigue. A few complaints, though, including it repeatedly thinking that the speed limit is 100, even when it’s actually 110 (pictured). Occasionally it dropped to 80 or 40, presumably after seeing some random sign off the highway. Pretty good driving efficiency with FSD, too, about 14kWh per 100km. See screenshots.

What to ask for in a battery installation
I suggest getting your installer to agree in writing that your battery installation will include: 1. Remote control via an app and/or website to monitor your battery and house power. 2. During a grid outage, the battery should provide backup for everything you need. 3. During a grid outage, solar continues to provide power. 4. The ability to curtail export of power to the grid when pricing is negative. 5. Compatibility with Amber Electric, if you might want to use them as your energy retailer. Let’s look at each in detail: 1. Using an app or website, you can: 1. Monitor power in and out of your battery, house and grid connection, instantaneous, daily and historical. 2. At any time, set your battery to a minimum charge percentage. 2. In the event of a grid outage: 1. The battery will switch over automatically. The installer should test it and show you. 2. The battery will power all of your home, up to the battery’s maximum power (which should be at least 5kW). 3. If you have three…

What do the kW and kWh measurements mean?
What do all the electricity measurements mean? 1. Australian household electricity runs at about 240V “volts”. All your power points and devices are 240V. This is basically a measure of the force used to push the electricity. 2. The “current” is basically the throughput of electricity, measured in Amps. It varies for different devices. A modern LED light bulb uses less than 0.1A (Amps). A toaster or heater will use around 8A. The typical maximum allowed by a standard power point is 10A. 3. The total power of the electricity is measured in watts. We multiply the volts by the amps (voltage x current) to get the watts. For example, if your appliance uses 5A at 240V, then that’s 5 x 240 = 1,200 W, which is 1.2kW (kilowatts). A light bulb uses less than 0.1kW. 4. The total energy used by a device is calculated as the power x time. For example, if you use an appliance running at 1.2kW for 10 hours, then it uses 1.2 x 10 = 12kWh (kilowatt hours). A light bulb could run for days on the…

Home battery introduction
Are you considering a battery for your house? Here is a basic introduction, based on our experience. I hope it’s helpful. Please comment about any errors, omissions or questions. 1. Why is there more talk lately about getting a battery for your house? 1. As of July 1 this year, the federal government will pay for 30% of your home battery purchase. This makes it 30% cheaper to buy one. 2. What’s the purpose of a house battery? 1. A battery provides power to your house, as electricity. 2. It can power anything in your home that runs from electricity, including your fridge, lights, power points, TV. 3. It can keep your house appliances running when there is a grid outage (a “blackout”). 4. If you have solar panels, a battery can store the excess power generated during the day, so you can use it at night to avoid paying for electricity. This is why it is often called a “solar battery”. 5. You can also charge a battery from the grid when electricity is cheap, and use it when electricity is…

Our Powerwall — one of a million deployed
Our home Powerwall battery is one of a million deployed so far. The Tesla app celebrated by listing the stats of our install, and the fleet as a whole. Our battery has saved us (and our neighbours via extension cords) from 13 days of blackouts, without any noisy smelly generator, or trips to refill it with petrol. Our solar system has generated 16MWh of energy so far, used by our house appliances, home battery, our car and exports to the grid. At an average ball park price of say 15c per kWh, that’s $2400 worth of electricity, with no ongoing running cost.

Emerald's Lost Woods Market draws a crowd
This is probably the busiest we’ve seen our town of Emerald, Victoria. The Lost Woods Market draws a huge crowd. It’s a beautiful stroll through the tall trees, past numerous stalls and food outlets, with Puffing Billy Railway choo-chooing past every now and then. It’s a magical place. We parked up the other end of town, starting off with brunch at Over the Road Cafe, then walked through the jammed main road to the markets. The generators of many stalls lined the back path, filling the air with slight fumes and noise. It’s a shame they don’t have grid power. We hoped to see some stalls powered by V2L EVs, as we’ve noticed at some other markets, but none here.

Tetris-ing four people, a fridge and luggage into a Model 3
We know our Tesla Model 3 can fit a 50L camp fridge. And we know it will take a large travel suitcase, or four people and some luggage. But we didn’t know if it would take all that at the same time. It took a fair bit of Tetris-ing, and the boot strained at the seams, but we managed to get everything in. I think we might need a bigger car. First stop at Eumundi Markets. We parked in the shade and later opened the boot so the fridge had some outlet for the hot air. Second stop along the highway at Burpengary for some fast food lunch. Then we delivered Erin and Isaiah to their accommodation in Brisbane before their flight back to Airlie Beach tomorrow.

Borrowing Nico's Jaguar i-Pace
On our way from Krommenie to Maastricht. We picked up Nico’s Jaguar i-Pace. Very swish. 0 to 100km/h in about 3.5s. Luxury interior trim. Neat console. It has fast DC charging but only does 3.6kW AC charging (compared to our Tesla’s 11kW). It’s about twice the cost of our base Tesla Model 3 at home. Jaguar had it for a few days to replace the battery. This is the first real example I’ve seen of someone actually needing to replace their EV battery, despite all the hype about it from naysayers. Fortunately, it was all covered under warranty. Our first stop was in Breukelen at a service center. Well, we actually stopped at two of these, because of mixed up convoy instructions. Next to the Shell petrol station here is a FastNed charging bay, with solar panels on the roof. Most service centres seem to have these, which is terrific. It kills me to stop for fuel like this. Stopping specifically for fuel (charging) is something I try to avoid. I prefer to just charge when I’m parked for some…

36 wild hours on battery in the Dandenongs
It’s been wild 36 hours here in the Dandenong Ranges. Yesterday afternoon, the power went out in our town of Emerald. We heard it was due to a fire somewhere. We sent out a few texts to our neighbours to offer our battery backup power. We ran our heavy duty extension lead over the fence and set up a power board on the front porch for phone charging. A few hours later, the grid was back up and running. But, the pending storm warnings made us cautious. Sure enough, an hour or so later, the storm hit. Heavy rain, pounding hail and strong wind. Marvin the robot mower happily sits charging out in the rain. But I didn’t fancy the chances of his camera eyes surviving the hail stones. I used the iPhone app remote control to drive it under our pergola, while the ice golf balls bounced on the lawn. Sure enough, the grid connection died again during the night, probably due to storm damage to power lines and other infrastructure. In the morning our neighbour reconnected to our power supply. We…

We bought a Mammotion robot mower
We bought a new EV! It’s all wheel drive, includes full self driving, with proximity sensors and just a front facing stereo camera. But it takes about four hours to fully charge and the acceleration is pretty slow 😉. It’s a Mammotion Tech Luba 2 robot lawn mower. We could have bought it online direct from Mammotion, but opted to buy it through a local service centre, Robotech Australia, just in case we need support or maintenance. Our lawn is about 1500 square metres. We bought the Luba 2 AWD 3000 model, which is rated to mow 3000 square meters, allows up to ten mowing areas, and handles extra step inclines. The base model does 1000 square metres, and allows less separate mowing areas. There are also 5000 and 10000 models. I followed the fairly simple hardware instructions to screw in the camera (which looks like Wall-E), screw the charging station into the ground, and assemble the transmitter (RTK) onto a pole.

Lake views at The Jindy Inn
After crossing Kosciusko National Park, we checked into The Jindy Inn last night. Great place with a balcony overlooking Lake Jindabyne. The room’s fridge had no freezer which meant we couldn’t refreeze our cold packs for our cooler bag. We didn’t bring the giant Kings Fridge on this trip. No microwave oven in the room, so we drove down the road to The Brumby Bar & Bistro to share a Brumby Burger (presumably not made from brumbies). Delicious! The inn included continental breakfast in the dining room. After slightly burning my finger on the reluctant conveyor belt toaster, I enjoyed autumn colour themed fruit salad and Greek yogurt on my cereal. After checkout, we grabbed a coffee from ESS BOARDSTORES, where they were happy to use our lactose free milk, from our cooler bag, since they didn’t stock that option. The cold temperature lowered the tyre pressures, as you can see on the Tesla’s screen. But they soon warmed up as we hit the road. Next, on to Cooma and then Gerringong.

An okay night at Mansfield Motel
Last night, we stayed in Mansfield, Victoria. The Mansfield Motel is conveniently a short walk to everything. Friendly reception. Our only complaint was that the hot water pressure was woeful. Oh, and the power points next to the bed touch the floor (why do electricians do that?), so you can’t plug in a power pack for laptop, phone etc. But that’s just being picky 😉. Like most of the areas we’ve been through this week, Mansfield is decorated by beautiful autumn trees, in shades of green, yellow, orange and red. The main street is split, with a park in the middle and a roundabout adorned with flowers. For dinner, we grabbed Indian takeaway from Curry Garden. For breakfast, we had toast and spreads. I mention this so you know that most of our road trip meals aren’t from fancy cafes 😉. After we checked out this morning, we grabbed a coffee at The Mansfield Coffee Merchant, 100m away. We drove off towards Kosciusko National Park, crossing the border into NSW, aiming to get to Jindabyne…

On a mission to find a left thermos lid
Down to the core of our mission 😉: to see if my thermos lid is still on the garden stake where I accidentally left it half a year ago, in the middle of Kosciusko National Park.

One last stop there for a quick toilet break and a stretch before takling the mountains. Oh, and a symbolic thermos lid of tea (in our second thermos). It would be dark soon, so we needed to get to Tom Groggin while there was still a glimmer of daylight by which we could search for the missing thermos lid. As you might have guessed and as probability and time would dictate, the first thermos lid was nowhere to be found. We took a photo of the replacement on the stake as a reenactment. It’s now time to move on. We continued east, past Thredbo and Mount Kosciusko, towards Jindabyne where we would stay the night. The mountains are beautiful. No snow on this trek through.

An 'EV' for the hedges
I tried out another “EV”, kind of – an Electric Vegetation cutter 😉. Okay, that’s a bit of a stretch. It’s an electric hedge trimmer. Emerald has so much vegetation, and our place is no exception. Hundreds of meters of hedges. The RYOBI electric hedge cutter is fairly quiet, instantly turns on and off, and is fueled for free by the sun via our roof solar panels. While cutting, it did occur to me that using a petrol powered hedge trimmer would be a much less pleasant experience. Much louder, with fumes in my face, heat and higher fire risk. I’d be dependant on an external fuel supplier to truck in petrol from hundreds of kilometers away, and I’d have to drive to a petrol station to get it. When the battery goes flat on this electric model, I just plug it in and walk away to do something else. It will take an hour or more to recharge, but I don’t have to do anything. Plugging in the battery takes a few seconds. If I really wanted to keep going immediately, I could swap with another…

Nine days of grid outage in Emerald
It’s been nine days of grid power outage here in Emerald Victoria. The community has pulled together to share resources. Today I received an SMS from Ben to ask if he could charge at our place. I assumed it was another neighbour asking if they could plug their phone or laptop in to the power board we laid out in the porch. We were the only house in the street to still have power after the storm hit, thanks to our Tesla Powerwall battery. It’s been charging up each day from solar panels on the roof. But Ben was actually after a place to charge his EV. I had forgotten about our listing on PlugShare during all of the neighbourhood blackout dramas. I said yes, no problem. Today he had driven from his home in Packenham east to Sale, then back west and up the hills to Emerald, and has a few more nearby drives to do before returning home. The navigation said he would get home with 8% charge, but that wasn’t accounting for extra stops. So, he wanted to play it safe.

Back home with battery power
We’re are back home in Emerald and have power! The grid is still out, and is expected to be down until mid next week. But our house is getting power from solar and our Tesla Powerwall battery. Driving back home (after our road trip to NSW), we could see why Emerald is still in the dark. Many power lines (and phone/broadband lines) are still down. Emerald featured in the first story on last night’s (Friday) ABC news: https://iview.abc.net.au/show/abc-news-vic At least one of our neighbours is running a fuel generator. Another has a couple of solar panels hooked up to a car battery for night lights and a 12V car fridge. Schools are effectively closed. The local petrol station had one pump going, with a long queue. We have offered our neighbours electricity from our solar/battery power. One family had no power for three days, but now we have connected some extension cords over the fence.

Powerwall hits zero during the grid outage
Well, that’s not good. The Tesla Powerwall at home has just gone flat (zero percent charge) at about 5pm today. Our new home town of Emerald is one of many affected by the grid outage in Victoria, after a wild storm hit on Tuesday afternoon. A couple of months ago, we had Lightning Energy install solar and a Powerwall battery at our new home. In a grid outage, the solar array is supposed to keep the house electricity going, recharge the battery each day, and keep the fridge cold. But the solar production stopped working when the grid outage started. Something is wrong with the installation. The battery has slowly depleted, until it hit zero percent two days later (this afternoon). I contacted the installer, Lightning Energy, a couple of days ago to hopefully fix it before the fridge died. No answer from service. So, I SMSed Andrew, who works for them and lives locally. He kindly offered to pop in on his way home to take a look. Here’s hoping we can get power from the sun back…

Wild weather hits Victoria
Wow, what a wild weather ride in Victoria yesterday. We’re still in NSW, but the Weather app summarised the weather at home in Emerald as “Fire Weather” 😮. The heat was followed by a heavy storm that knocked down many trees and power lines. In the middle of the day, wholesale electricity prices peaked at a hundred times the norm at nearly $20 per kWh (normally under 20c per kWh). I checked our home remotely using the Tesla app. It was exporting power from our battery (and solar) to help keep the grid supply going, whilst paying us about $100 per hour for the supply! Our battery has continued to supply power to our home during the blackout. We messaged some of our neighbours an invitation to come over and plug in any needed devices (such as phones or a portable fridge). A few of them also checked on our house for us. Great neighbours and community ☺️. We might need to also offer them showers because those with on demand gas hot water often need electricity to light them. All the petrol…

The team from Lightning Energy installed the undercover pieces today, while it’s raining, and deferring to tomorrow the installation on the roof of the solar panels, if the sun comes out. We had originally scheduled this installation for December 11 and 12, but rain on December 11 saw it canceled. We had this Tesla wall charger at our last house in Saratoga NSW, a year ago. The new owners there didn’t have an EV, so we modified the contract for us to remove the EV charger. It has sat in storage until the removalists delivered our belongings here a few days ago. It wasn’t really practical for us to bring the Tesla “Powerwall” battery with us from the old house, so we bought a new one for this house. It costs about $15k, which is a lot. There are cheaper battery options, but we know the Powerwall has a large capacity compared to cheaper batteries, and works well with the app, scheduling, blackouts, etc. We have heard from a few people in Emerald and the Yarra Ranges in general that…

A bug-spotted windscreen, with no clean-up
Final leg to the NSW Central Coast today. First stop for bladders, so we pulled into the next service center along the Hume Highway. A fresh spotting of bugs adorned the windscreen. But there’s no cleaning facilities at the chargers 😞. We pulled into the adjacent service station. I opted for the least busy section, which was for trucks, planning to get out quickly. I grabbed the handle of the cleaner from the bucket, and wiped the windscreen a few times. When I went to dry the drips from my hands, I realised that the handle was covered in grease! And now also my right hand. It took some time and effort to get that off, so as not to wipe it on the white interior of our car.

Tyre rotation — and a recommended replacement
Slightly overdue for another tyre rotation (16,700km since previous check, but due at 10,000km intervals). So, I booked one in via the Tesla app, which quoted $71.28. Mobile service came to me. Amar, the Tesla technician, was very friendly, efficient and helpful. All his tools were in the trunk and frunk of his Tesla Model S service vehicle. He showed me that the tyres had unevenly worn, so the inside tread (on the right in the photo) was below spec on all tyres, requiring the replacement. He said he could cancel today’s call-out (so, no cost to me) and book in a tyre replacement at the Tesla service centre (big cost). I asked him to make it so. Follow up: See the post about the subsequent actual tyre replacement at the service center, here:

A visit to Snowy Hydro Discovery Centre
Monday morning: We visited the Snowy Hydro Discovery Centre. Very interesting wide screen video presentation, models, and other exhibits. Amazing how we can generate electricity from rainfall and melting snow.

Hiring snow chains for the Alpine Way
Venturing from Corryong to Khancoban, we decided to keep going east, through the Snowy Mountains along the Alpine Way, past Thredbo to Jindabyne. The road has signs that require all two wheel drive cars to carry snow chains. So we hired some from Khancoban, which could be returned in Jindabyne (“one way hire”). In the end, we never actually had to fit them, since all the roads were cleared. We stopped a few times along the way, including a rest stop next to the origin of the Murray River (pictured). I left the cap/cup from my thermos on one of the garden border markers near the toilet block, so I wouldn’t drop it as we clambered down to the river. But I forgot about it as we walked back to the car and drove off 🤦♂️. If you happen to be driving past Mount Kosciusko, please keep an eye out for it 😉. We returned the snow chains on the other side of Mount Kosciusko at in Jindabyne. The service stations were packed with people queuing for petrol, I guess on the last day of the school…
Formerly: Tesla Tripping
Come along on our EV road trips around Australia and Europe, and follow as we progressively electrify our home in Emerald, Victoria.
Join us on the road. We set off in late 2022 and drove eastern Australia in our Tesla Model 3 — Sydney, Dubbo, Armidale, Brisbane, Cape Tribulation, then down through Queensland and back. We've since upgraded to a Model Y.
We've kept exploring — Uluru, the Snowy Mountains and Gippsland, and a longer run through Europe in 2024. There's plenty more on the map, so come along for the next leg.
At home in Emerald, in Victoria's Dandenong Ranges, we're progressively electrifying everything: rooftop solar, a home battery, a hot water heat pump, air conditioned heating and cooling, and EV charging straight from the sun. We're going fully electric, off the gas.
Got questions, or insights of your own? We'd love to hear them — please drop a comment on any post.
