The Pontville centre near Hobart has been re-branded as an alternative place of detention by the Immigration Department and is being used to detain almost 300 unaccompanied minors from places like Afghanistan, Vietnam, Iran and Sri Lanka.
Authorities say the 11-year-old child is being held along with two cousins but the immigration department won't say how long the children have been detained.
