I think at the moment it's not viable but this can change in the years to come. It will also involve the government to help fund the EV infrastructure but in a way that will also involve the people cause they have to vote for the people in charge or vote for the props to pass. Not sure how it works in Australia or other countries but when I was in California, people in the state could vote for their governor and the changes in the law like legalizing weed etc.
For my current country Malaysia, I think it will be a slow progress. Currently the market for ev is quite small. To really make it work, I think ev cars need to be more affordable and the infrastructure needs to be there to support it. Until this happens I would say it's not viable for Malaysia
As for addressing the fossil fuels, I think for humanity yes we should. We should care about how our other future generations will live on Earth. We shouldn't make the world a worse to live in my opinion. We should look at ways to conserve our non renewables resources and try to utilize renewable resources so we can maintain life on Earth. I think a lot of previous generations didn't care much about what happened to the planet but now people in the last two-three decades are starting to make changes after seeing the effects of pollution, global warming etc.
