A well-respected hypothesis--that Australia is and has been relatively
depauperate in large carnivorous mammals (Tim Flannery)--may keep my
hypothesis alive here.

Considering that your hypothesis seems to depend on small egg-eating mammals, not large carnivores (and Australia certainly has the former, including dasyures and bandicoots), I don't see why.
