What was life like for Aborigines before the first fleet arrived?

They arrived in waves of different peoples between about 50,000 and 5,000 years ago, taking up tracts of land which was either unpopulated or displacing existing occupants. They lived in a clan and tribal society harvesting Natural Resources for subsistence. Each group had its own traditional practices and religious customs. The males were trained as warriors and inter-tribal fighting cost about a thousand deaths a year. They followed the rhythms of climate, animal migration and foodstuff growth.
