This is good news, but some of the biggest barriers to wind and solar power have never been production, but storage and transportation. And renewable sources can still rely on fossil-fuel as a backup, for when they are not producing. Having to be responsible for 100% of electrical production is an order of magnitude different.
Luckily enough, Australia doesn't really lack for space. There is plenty of desert in the interior of the country that I'm sure no one will care if we pave it with solar cells. But you still need to get that electricity to the people living elsewhere in the country. Electric lines have a limited distance that they can efficiently transport electricity before the resistance starts to make it very expensive. And, there needs to be some other source or storage method for producing electricity at night.
Wind energy has even more issues with variability, for which the solution is usually "build lots windmills everywhere". In other words, both kinds of power production are going to require extensive capital investment to be viable on a wide scale.
I eagerly await the day that humanity is no longer dependent on non-renewable resources for most of our energy needs. I think it has the possibility of happening within my lifetime. It's not going to happen cheaply, or overnight*.
And I still view fossil-fuels and nuclear power as valuable and effective stepping stones.
*Unless someone develops a cheap, room-temperature superconductor, in which case the Sahara desert will rapidly become the solar-energy capital of the world.
