It is highly likely that Homo Erectus reached the island of Flores in Indonesia, where it evolved into Homo Floresiensis.
What if they had reached Australia, along with Papua New Guinea and Tasmania (which have been one landmass at various times in the past 2 million years).
It would be highly likely that Homo Sapiens would have replaced Homo Erectus once they arrived in Australia. However, it is possible that most of megafauna which went extinct after Homo Sapiens arrived in Australia would still survive.
One possible effect would be that the Agricultural populations of the highlands of Papua New Guinea might be able to domesticate species of Diprotodon (if its gestation period was similar to that of cows or horses). Right now I can’t think other megafauna which went extinct in OTL, that could have been domesticated.
