Asylum seekers detained on Manus Island say Reza Berati was thrown off a balcony before being beaten to death.

Fresh allegations surrounding the death of the Iranian asylum seeker emerged on Friday during an inspection of the centre, organised as part of a court inquiry into last month's violence.

While AAP - one of two Australian media organisations granted rare access to the Manus Island facility - was not permitted to interview asylum seekers, many spoke openly and shouted to the visiting party.

In one part of the facility known as Mike compound, transferees pointed to a black stairwell that snaked up between stacked, white shipping containers that served as four-man bedrooms.

"They hit him and he fell from here and they hit him till he died," said one asylum seeker. "They hit him in the head until he died."
