> Not really, again 20,000 years and Australia is a big, big place. Like really big, and most of these creatures had wide ranges. I don't find the human hypothesis has enough stock to stand up under scrutiny, especially considering these extinctions happened at the end of an ice age.
north america and asia are big, but it seems very possible that (with other factors) humans helped push mammoths to extinction.
you are also assuming equal dispersion across Australia, which may not be the case, especially if climate change was cutting back their habitats - like it was with the mammoth.
