Were there Aborigines living on the Australian goldfields?

Yes, there were Aborigines living on the Australian goldfields.

Many Aborigines worked on the goldfields, both reluctantly and willingly, as cooks, cleaners, guides and miners. Gold rushes caused a major disturbance to Aboriginal economies, and were often accompanied by violence towards Aboriginal people. There was also prejudice and discrimination against Aborigines on the goldfields. Nevertheless, some Aboriginal people did find that working on the goldfields gave them a little more power in the colonial society and economy, while others gained a sense of liberation from the harsh social environments of the Australian frontier.
