Tall metal fences topped with sharp barbed wire surround Sydney’s Villawood Immigration Detention Centre, but detainees say drugs are easy to come by.
Visitors to the centre sometimes smuggle them in and, according to detainees, guards and staff bring them in to sell.
In a video obtained by SBS News, a detainee is seen in his room casually and openly constructing a makeshift pipe and smoking what he says is "ice" (crystal methamphetamine).
In other footage, detainees are filmed smoking what they say is marijuana and "bupe" (buprenorphine, a heroin substitute), with one man explaining on camera they usually inject bupe and at times share needles.
