I've written on this subject more extensively on another page, Australia's energy future.
While the corrupt Australian Morrison Government does everything it can to support fossil fuels the Australian state governments and industry see that the nation has a great future in supplying the world with clean energy.
unattractive at least in part because its cost had increased while the costs of renewable energy had greatly decreased. For example, in August 2017 two partly built nuclear power stations were abandoned in South Carolina, USA, following huge cost blowouts. On top of this Nuclear has problems with:
In 2017 Lazard produced its latest (at the time of writing this) Levelized Cost of Energy Analysis (Version 11.0). The figures in the table below were extracted from that report; the costs are for the USA, are in US dollars and are for utility-scale installations. I have selected only the figures for on-shore wind, solar PV and their main competitors in non-renewables: gas combined cycle, coal and nuclear.
Lazard's analysis indicated that in Australia, solar was a little less expensive than in the US and gas power a little more expensive.
Also see Lazard's Levelized Cost of Energy and Levelized Cost of Storage 2018. In it the cost of onshore wind power had decreased by a further 3-7%, solar had decreased a further 13-16%; there was little change in the cost of the other technologies.
The general expectation is that the cost of wind power and especially solar power will continue to decrease.
