There is enough uranium in Australia to last us a few ten thousands years. Sure, fossil fuels are cheaper to harness right now, but they are nowhere near what is possible and feasible.

Not according to any analysis I've seen, most of which project about 80 years' supply at present usage rates. Six if we lean on nuclear for 100% of energy needs.

Mind: the minimum feasible grade for extracting energy-positive uranium is around 0.02% grade (http://www.stormsmith.nl/i05.html)

The Wiki article you link lists a variety of predictions on global peak uranium. The pessimistic ones, which are a minority, mostly predict that it has already happened (1980, or so). There appear to be 3 predictions that average around 80 years, and one predicts with a 6-fold increase in consumption it would last 12 years.

Meanwhile there are just as many optimistic predictions that it will last for thousands of years, if not longer. What makes you so sure it's only 80/6?
