The short answer: before you buy an EV in Australia, get realistic about three things the dealership sticker will not tell you: real-world range, charging, and running costs. Independent testing has consistently found real-world driving range comes in below the lab figure, so plan for less than the number on the window. Home charging overnight is by far the cheapest way to run an EV, while public fast charging can cost close to petrol. And a few ownership costs, like some repairs and battery health over time, deserve a look before you commit. An EV can be genuinely cheaper to run for the right driver, especially with home charging. The trick is matching the car to how you actually drive, not to the brochure.
I look at the total cost of ownership with clients, not just the loan repayment, and EVs are where that habit pays off most. Here is what to check.
No, the real-world range is usually lower than the lab figure, so treat the sticker as a best case. The lab number is a mandated figure reported under the Australian Design Rule standard and published on the Green Vehicle Guide. Independent, government-funded testing by the Australian Automobile Association has repeatedly found EVs travel less than that in real driving. Across the models it has tested, real-world range has come in roughly 3% to 31% below the lab claim depending on the car, and in its testing to date, none of the EVs matched their lab range. As a rough planning rule, take the claimed range and multiply by about 0.8 for an everyday number, and expect a bigger gap at highway speeds and in extreme temperatures.
Charging comes in three broad speeds, and where you charge matters more than most buyers realise. Home AC charging is the slowest but covers most daily driving overnight, and it is by far the cheapest way to run an EV, especially on an off-peak rate or with solar. Public AC charging at shopping centres or workplaces is faster but still not fast. DC fast charging at dedicated stations or highway stops can take a battery from about 10% to 80% in roughly 20 to 40 minutes, but it costs more, sometimes close to petrol on a like-for-like basis. If you cannot charge at home, check what public and workplace charging sits near your regular routes before you buy, because that convenience is the whole EV value case.
For a lot of drivers, yes, but it depends on how and where you charge. For average daily driving with home charging, running costs are meaningfully lower than petrol. The picture is less clear for high-mileage highway drivers, who see a bigger range gap and use more energy at speed, and for apartment dwellers without home charging who rely on public fast charging. So the honest answer is that an EV rewards the suburban driver with a driveway more than the highway commuter without one. Work out your real driving pattern first, then the running-cost saving becomes easy to estimate.
A few EV-specific costs are worth knowing before you sign. Some EVs use large single-piece body castings rather than smaller replaceable panels, which can make minor damage more expensive to repair, and fewer independent repairers are set up for EV work. Battery health also declines gradually with age, like a phone battery, so it is worth checking the battery warranty terms specifically, often around eight years, rather than assuming the general vehicle warranty covers it. None of this is a reason to avoid an EV, but these are the costs the dealership rarely walks you through.
Each option trades price against certainty, and battery health is the EV-specific wildcard. A new EV gives you the full vehicle and battery warranty and the latest range and tech, at the highest price and the fastest early depreciation. A demo is near-new with the remaining warranty intact, typically at a useful discount. A used EV is the lowest entry price with the most choice, but battery health is harder to judge than engine wear on a petrol car, so ask for a battery state-of-health check and confirm exactly what is left on the battery warranty and whether it transfers to a new owner, because that varies by manufacturer and is not automatic.
If you are employed and buying through salary packaging, an eligible EV can be tax-effective, but the rules are specific. Eligible battery electric cars can be exempt from fringe benefits tax on a novated lease, which the ATO allows for eligible zero or low emissions vehicles that meet its conditions. Two points to keep straight: plug-in hybrids are no longer eligible for that exemption from 1 April 2025, and the exemption is under review by the government until mid-2027. Because the tax side depends entirely on your circumstances, confirm it with a licensed tax adviser before counting on any saving.
How accurate is the range on a new EV in Australia? Usually optimistic. Independent testing by the Australian Automobile Association has found real-world range roughly 3% to 31% below the lab figure depending on the model. Plan for around 80% of the claimed range as a rough everyday rule.
Is it cheaper to charge an EV at home or in public? Home charging overnight is by far the cheapest, especially on an off-peak rate or with solar. Public fast charging costs more and can approach the cost of petrol on a like-for-like basis.
How long does an EV battery last? Battery capacity declines gradually with age. Many EVs come with a battery warranty of around eight years, separate from the general vehicle warranty, so check those terms specifically rather than assuming.
Can I get a tax break on an electric car? If you are employed and use a novated lease, an eligible battery electric car can be exempt from fringe benefits tax under ATO conditions. Plug-in hybrids are no longer eligible from 1 April 2025. Confirm your situation with a tax adviser.
