Why didn’t Australia have advanced civilizations

by jiggyboneless

I think it’s interesting that Australian Aboriginals didn’t develop advanced cultures and civilizations when every other continent that has been inhabited has, especially since cultures such as those in Indonesia and the pacific islands were only a few hundred miles away, and at times even traded with eachother, why is it even when coming in contact with more advanced peoples from Indonesia through trade, wasnt there a advanced Australian civilization
