A good place to start is Wikipedia’s article on the Gurindji strike.
Green Left Online has a lengthy article titled The Gurundji strike and land claim which originally appeared in the Green Left Weekly, issue number 197, 1995.
The National Archives of Australia Fact sheet 224 details records held by the archives relating to the Wave Hill walk-off.
A couple of useful print items are:
- Unlucky Australians
- Hidden histories : black stories from Victoria River Downs, Humbert River and Wave Hill Stations
