PNG dominated over the NRL star studded line-up with tries to captain David Mead and Luke Page to beat the Fijians in the first 40 minutes.
Early nerves got the better of both sides in the opening exchanges with some scrappy play.
After finding their rhythm, the Kumuls were relentless, launching wave after wave of attacks.
Some classy play from Kumuls’ hooker, Kurt Baptiste, allowed Mead to slice through the defence and score.
The win was sealed late in the match when vice-captain, Ase Boas, set up a charging Page to crash over.
Next up was the showdown with the Australian Kangaroos.
Kumuls coach Michael Marum would have been even more impressed with the defensive effort in keeping the defending Rugby League World Cup champions at bay for most of the match.
The Australians managed to score only four tries.
The Kumuls’ points came off a try from Rhyse Martin.
Fiji Bati were handed their second loss going down to the Kangaroos 18-0 in the last forty minutes of the tri-contest.
