Trevor, as I am retired I share some of your views. While i would love to have an EV for environmental reasons, the limited range is a big problem for me, as my son's family live in Brisbane and it's 800kms door to door. I can pretty much do that on one tank of petrol in my little 1.2L turbo Renault.
My other trips are mainly down to my daughters place in northern Sydney, which could be easily done with an EV (about 220kms round trip), but any running around down there would require a charge point. My annual kilometres does not exceed 10,000kms, and has been much lower this past year, like 5000kms.
My other point is that we need to consider the environmental cost of actually building an EV for us to buy. The environmental cost of building my 2015 Renault is already a sunk cost and looked at over all the years, it gets cheaper the longer I keep it. A fuel efficient vehicle, just makes much more sense.

Finally, Australian government policy does not look like ever supporting the subsidies that our European friends enjoy. They are happy to collect petrol excise taxes which mostly goes into general revenue. Despite owning a diesel previously (for 13 years), their days are over and they should be taken off the roads. New diesel passenger car and 4wd sales should be banned, and any existing diesels in use should not be allowed to be re-registered once they are ten years old. Restricting diesel fuel sales is another incentive for change, along with raising the price every year.

At present, in Australia, EVs seem to be a toy for the wealthy looking to make a statement. I see a fair number of Tesla's around this holiday area on the weekend, and in the Hunter Valley; likely wealthy Sydney residents having a day trip within their available range.
