Aboriginal Australians through the 20th Century? PLEASE PLEASE HELP!?

Hi i'm from Australia I'm currently studying for my School Certificate (Year 10 Examination) and I'm absolutely freaking out. I have a very good knowledge and understanding of basically all of Australia's history starting from 1770 to the present day, but I am getting SO confused about Aboriginal things. It's kind of a huge thing in Australia. I'm just trying to figure out the timeline, starting from 1901 (Federation and beginning of the White Australia policy) to 1997 (Mabo Case) but i honestly cannot remember ANYTHING in between apart from imilation, integration, the tent emby and a few other things. Can someone PLEASE help with a simple timline of all the REALLY IMPORTANT parts of what happened to Aborigional Australians throughout the 20th Century (1900-2000) ?? I would be so so so grateful. thanks to anyone who comments!!
