Australia has plenty of insolation and most power consumers are packed densely enough not to worry about the upkeep of large grids.
Aside from uranium, we also have a much more plentiful thorium to use as a fission fuel. We definitely are not running out of that. But, thorium power plants can be more expensive, and byproducts of thorium cycle are less valuable, so it’s worth comparing that to running a renewables-based grid again.
