Yes SOUTH Australia is getting drier, but TROPICAL Australia is expanding southward at the same rate. For every degree of latitude that shifts from dry to desert another degree of desert shifts to wet and dry tropical climate patterns.
When you focus on just one spot while talking about a place as big as Australia you miss a great deal of the picture.
Since 1979, the planet’s waistline been expanding poleward by 56km to 111km per decade in both hemispheres. Future climate projections suggest this expansion is likely to continue, driven largely by human activities – most notably emissions of greenhouse gases and black carbon, as well as warming in the lower atmosphere and the oceans.
Rounding that to 50-110 km a decade or 5-11 km a year what does that mean for Australia? Well sediment studies logging the last 50 million years or so of data strongly suggest that north Australia will not only continue to be tropical jungle, but also that the jungle will spread a long way to the south as the global climate warms. On the other hand the same study shows south Australia and eventually Tasmania will have their moderate climate replaced with a desert climate.
So if you are a smart person in Australia what do you do? My recommendation. if you live in the south sell while your land is still valued and invest the money you get in new land as close to the climate zone line on the dry side of the convergence in the north. With an advancing rate of 5-11 km a year and skill in picking your location you should end up in a wet/dry tropical zone soon after you invest and then you can grow any of the crops typically grown in the wet and dry tropical climate zone for the foreseeable future.

lengthy study confirming these paleoclimate reconstructions.
