Opinions / data, let's go with the data.
It's really not. Australia is mostly uninhabited, with most people living in very few high density places.
The average commute distance in Australia is 16 kilometres; 90% of Australians live on the East Coast; 73% of Australian's commute less than 20 kilometres.[1]
Even Western Australian has people living outside of Perth, which, by the way, is the most remote centre of commerce in the world, has an average commute distance of 20.4 kilometres.[1]
The average Australian vehicle travels about 12,100 kilometres annually, that's all vehicles including freight vehicles.[2] The average household in Australia owns 1.8 cars[3], so very many Australian's would be well served by owning at least one purely electric vehicle, but don't.
Plug-in hybrids are mostly not a thing here.[4]
