According to a naive analysis of the BOM data for southern Australia
there has been no significant change to rainfall in the S over the
past 100 years. The recent drought is therefore just most likely a 
normal deviation from avg conditions, albeit a record one.

In the northern region avg daily rainfall is on the increase by around 70 mm
per century.

But an associated rise in avg daily min and max temperatures of
around 1 C per century (this is situation in N; in S the avg daily min 
is increasing faster than the max) will claw back must of the increased N 
rainfall through avaporation, as well as increase the demand for water even
if all other things are equal. 

And with an increasing population all things are not equal.
