Gas is far superior to Coal- If you can get the hundreds of thousands of tonnes needed---
Gas can and is burnt in a gas turbine, like an aeroplane jet engine, and drives an alternator direstly, avoiding boilers, steam, cooling towers.
Gas turbine has very fast startup- minutes
Coal startup is probably 24 hours. Coal is much cheaper.

Coal fired power stations with capacity to meet 100% of australias needs
Run these at 60% of capacity
Use Gas to top up surges in demand, AND perhaps a sprinkling of windmills to keep the idiots happy.
