Micklo Corpus, a Yawuru traditional owner of country around Broome, WA, has been camping at the entrance to Buru Energy's Yulleroo gas field for 15 months.
This week, he was moved on by police for blocking Buru Energy vehicles from accessing a gas fracking site.
Buru Energy is planning to frack two wells at the site 70 kilometres east of Broome to test its potential to produce commercial quantities of gas.
Corpus is angry that even though the Yawuru people have been granted native title over the area, it does not give the legal right to stop fracking.
