"I repeat no one, will build new coal fired electricity generators in Australia."
At this stage, no, but I wouldn't rule it out in the future and there is still a chance of keeping the ones in use working to fill the gap until nuclear becomes viable and operating. Gas is the one to look forward to.
Never say never. There is an interesting election in the near future. Hopefully the greens and teals will get a kick where it will hurt them.
