The first group of 40 asylum seekers flew out of Christmas Island yesterday for Manus Island, Papua New Guinea, under Australia's tough border protection policy.
The group were scheduled to leave Australia on Tuesday evening but bad weather delayed the transfer.
The Australian government says the transfer formally brings into effect the Regional Settlement Arrangement agreed to on the 19th of July.
In a statement, it says the refugee claims from the single adult men will be assessed under PNG law and, if found to be refugees, the men will be settled in PNG.
It also says transfers to the Manus Island regional processing centre will continue regularly.
