What a great figure, fantanstic to see another Aussie figure.
Just one point - the Australian Imperial Forces in WW1 never had cavalry.
The Australian Light Horse were Mounted Infantry and they fought mainly as infantry (no horses) at Gallipoli and on the Western Front. Only in the Middle East did the Light Horse fight in this way, and were credited with the last great "cavalry" charge in history - the attack at Beersheba in Oct 1917).
It's difficult to tell from the single photo, but Australian Lighthorsemen wore emu feathers in their slouch hats to distinguish themselves from the infantry, and I can't see any emu feathers on this figure.
Also the colour of the pugaree (the cloth band around the base of the hat) should be a buff/ khaki drill colour, rather than green).
Those minor points aside, the paint job is great and the figure is a beauty.

Tony
