The two teams met at Beenleigh Buffalo's AFC in Queensland.
Much to the Chiefs credit they readjusted and kept PNG goal-less in the last quarter to end the game on a high.
Final scores PNG 49 defeated Chiefs 17.
It was a good hit out for both clubs as they head towards the start of the International Cup this weekend on August 6.
PNG will take on Ireland in a replay of IC14 Grand Final and the Chiefs will take on NZ.
The Nauru Chiefs head to Melbourne today.
