Dylan Voller joined a small crowd protesting against the conditions in NT detention centres as the Royal Commission into Juvenile Justice resumed hearings in Alice Springs on March 13.
Footage broadcast on the ABC showing Voller being tear-gassed, spit-hooded and shackled to a restraint chair prompted Prime Minister Malcolm Turnbull to call the inquiry.
Speaking outside the commission, Voller said he wanted to support the other young people giving evidence.
“Everyone else from around the country and around the world supported me, so it’s my turn to give back while I’ve got an open voice,” he said.
“It is a hard process to go through and I sincerely hope the government listens to the commission’s recommendations.”
