Coal plants are indeed doing a great job of making themselves extinct around the world. The problem is countries like Australia where they manage to defer that inevitability through government handouts, protectionist legislation, and overtly anti renewables policies. High prices help. Unstable prices help more. Coal mines are going to have a tough time dealing with rapidly dropping demand and making the necessary investments to keep on operating. Though prices are high, that's mostly because of competing mines not managing to survive. Nice for the ones that remain; but opening a new coal mine would probably be an investment that would be problematic mid to long term.
Either way, Atlassian speeding things up a little might have a positive impact. Either way, the Australians could do more to nudge their country towards being a bit less dependent on burning stuff to keep their ACs going. It's not that hard. Most of their cities are close to oceans (with lots of wind power) and the continent is well known for having a lot of exposure to sun light throughout the year. Also, it does not have much of a winter even in places like Melbourne and Adelaide on its South coast, which have a latitude (37 degrees South) that is comparable to that of places like California (Santa Cruz), Northern Africa, etc. in terms of amount of sun light.
