There are at least three gridded surface climatic climate datasets available in Australia, they differ by the interpolation method. They all operate from the BOM network of weather stations
...
for Australia. They each use the same underlying BOM weather station data (albeit with possibly different quality controls applied). They differ in the interpolation method used and the variables provided.
