Australian aboriginal A.I.F.

[High Wood]

I have purchased a small collection of Australian Great War post cards which included this stunning image of an Australian soldier. He appears to be serving with the 1st Division and possibly 4th or 8th battalion but please correct me if I am wrong.

I wasn't aware that native Australians served in the A.I.F. but then I know very little about the A.I.F.

If there is any way of identifying this soldier I would be very pleased to know.
