I read a great book by Tom Kenealley called A Commonwealth of Theives, a great historical read on the settling of Australia, the first fleet and Sydney Cove etc. He gives a fair bit of detail of the issues regarding the relationships between the indigenous culture (The first Australians) and the invaders (or settlers), but his focus is broader than these issues.
I have just watched episode 1 of the SBS doco The First Australians, similar in date and geographical foci to Keneally, but rather more a direct commentary on the indigenous people and the effect the invasion of their land had upon them.
If you are interested in our history as a nation and in particular the history of our interaction with the first Australians, the Aboriginal people of the land we live on, I highly recommend this series, viewable online.
