Get yourself a copy of Tom Cole's book - Hell, West and Crooked.
Not a hunting story per se, but a damn good read about a part of Australia which was still wild, unsettled and empty up to about Christmas 1941. The years from the mid-'30s to 1941 are about Buffalo and Crocodile hunting in what is today the NW corner of Kakadu National Park.
