Australian Prime Minister Malcolm Turnbull rejected calls Wednesday to expand an inquiry into the mistreatment of children in detention centres.
On Tuedsay, Turnbull ordered a Royal Commission investigation into the mistreatment of children in a Northern Territory jail after revelations of abuse were broadcast on local television.
Former workers in youth detention centres in Queensland said they were sacked for speaking out about violence against minors inside the institutions, national broadcaster ABC reported Wednesday.
Turnbull said state governments should hold separate enquiries into their own detention systems and that the Royal Commission would focus exclusively on the Don Dale Youth Detention Centre in Darwin.
"If you spread it out to be an all-Australia inquiry, it would go on for years and you won't get the answers you need in respect to the Northern Territory," Turnbull told the ABC.
Some lawyers called for the Royal Commission in the Northern Territory to include Queensland and other states.
"There's systemic failures across the system," lawyer Joshua Creamer told the ABC.
On Monday, graphic footage showed boys between 14 and 17 years old in prison being sprayed with tear gas in their cells, strapped to chairs with hoods over their heads and being beaten by guards. The video was aired by the ABC television programme Four Corners.
