Coal is dying as an investment but existing coal plants will likely run for a long while. Overall demand for energy is rising, the new demand is being met mostly with renewables, but there is a small amount of that increase that is being met by a small increase in coal usage. As renewable manufacture gets faster and more efficient I expect the coal growth will reverse, but it is all about when. If it happens quickly we have less apocalyptic damage. If it happens slowly then we will be more fucked.
Solar is far and say the cheapest form of new energy to roll out. Wind is a not so close second. Coal is getting more expensive by the day. The only reason to roll out coal is insufficient production of solar and wind. It takes time to increase manufacturing capacity but we are getting there and we can do this.



As a fellow Aussie I share your conclusion, though the Made in Australia plan from the Albanese government seems like it could change the game. Producing solar panels here would make purchasing them cheaper even if just from the shipping costs. Add the federal investment and the creation of demand and it should get cheaper again.
Now I do worry about things going the way of the NBN, starting with a goal of future proof fibre to the home being chipped away by the LNP until it was a small upgrade on internet service funded by the government but not anything like the goal. I want good green tech, not just barely solar sometimes.
