Australia's Department of Immigration and Citizenship has announced the third transfer asylum seekers - made up entirely of family groups - to Manus Island in Papua New Guinea.
The group of 20 - consisting of 16 Sri Lankans and four Iraqis - arrived on Saturday.
They were accompanied by Australian Federal Police, immigration staff, interpreters, children's services and medical staff.
On arrival in PNG, the group underwent local immigration clearance processes before being moved into the regional processing centre.
The department says the completion of this transfer reaffirms the strong message of deterrence for anyone considering risking their lives on dangerous people smuggling boats.
