We keep on self-inflicting these disasters. Closing the Port Augusta coal fired 520MW in ~May 2016 started the explosion in wholesale electricity price. Despite all that evidence Hazelwood was allowed to close which will put the eastern grid at minus 1,600MW greater risk in subsequent summers. It is simple stuff. The solution is so easy and simple.
Cease yakking about and ditch any idea of a CET ala Finkel.
Scrap the RET.
If a Govt takeover of Liddell is required to improve its reliability and extend life just do it.
There! - electricity grid improved and power prices should moderate.
