First, according to "Magnificent Mihirungs" it seems highly unlikely that gastornithids and dromornithids were, in fact, predators (See chapter 12). The authors also attribute the extinction of mihirungs, at least in part, to the drying of the continent and to aboriginal fires, which eliminated forst-living browsers like the mihirungs and favoured grassland birds like emus.

Also, remember that humans DID wipe out the emu species on Kangaroo and King Islands, ase well as the population on Tasmania (in fact, the latter happened twice, as birds were reintroduced and then wipied out again).
