Mungo Man's DNA suggest he might be an erectus/homo sapien. This wouldn't be a problem for the Creationists because, as I understand them, they consider erectus, Neanderthal and homo sapien as just human variations.
I read one theory that places homoerectus in Australia prior to the arrival of 'moderns' 60k years ago and that the Aboroginies(sp) of today are the result of that meeting. (Ansestors of a combination of the two)
