An order of magnitude higher and it'd be of similar magnitude to the entire USA.
I tend to think of Australia as pretty similar (if literally polar opposite) to Canada. Similar population and standard of living on a similarly large but largely inhospitable landmass.
Australia has almost everything wrong you can think of climate-wise: cold Antarctic currents hitting the west coast causing dry winds with little moisture, on the east coast there's a narrow strip between the coast and the long N-S mountains that gets moisture, but even then the mountains are barely high enough to trap winds and cause rainfall. The very north gets monsoons, the inland is a baking desert and only the very south is temperate.
If you want an idea of scale, there's a single cattle farm in Australia operated by less than a dozen people that is larger than Texas.
