Average commute or distance traveled per year isn't the interesting number. If you're considering an electric car with a range of 300km, it doesn't matter if your average commute is 16km or 100km, what matters is, do you take trips in excess of 300km?

> The number of survey respondents who have taken a road trip increased to 91.9% in 2024 from 88.4% in the same survey in 2022
And if anything, fewer total miles traveled per year would make EVs less attractive there because of less in terms of fuel savings.
> Plug-in hybrids are mostly not a thing here.
Plug-in hybrids are relatively new because they're basically normal hybrids with bigger batteries, so the batteries had to get cheap and light enough to make that work, and they got faster adoption in countries like the US because of tax incentives that favor PHEVs over traditional HEVs. Meanwhile from your own link, 25% of new cars in Australia are some type of hybrid of BEV, compared to 19% in the US. Consistent with "they are buying more fuel efficient vehicles", it's just that those vehicles are turbocharged low displacement or hybrid SUVs.
It's possible that the difference in tax incentives is causing carmakers to allocate PHEVs to the countries providing incentives specifically for those given a finite amount of battery production capacity, but according to your own numbers PHEVs are a good fit for Australians. Average commute is well within their all-electric range but then you still have no trouble taking the occasional road trip.
