Australia has flown more than 200 asylum seekers from Christmas Island to Manus Island in Papua New Guinea since the Government announced a new policy for dealing with people trying to reach Australia by boat.
The sixth group since the policy change on 19 July was flown to Manus on Tuesday morning.
The 39 adult males included 35 Iranians, two Pakistanis and two people who claim to be stateless.
The Department of Immigration said there is no cap on the number of people who can be sent to Papua New Guinea, and transfers will continue on a regular basis.
