With Maika Sivo and Kurt Donoghue both claiming a double at Santos National Football Stadium, the Bati blew the game open early in the piece with the Kumuls unable to match the visitor's speed and class in attack.
However, the Kumuls refused to lie down despite the scoreline, orchestrating two tries late in the second half to keep the passionate PNG faithful on their feet.
The Kumuls opened their account in the third minute when halfback Lachlan Lam shifted the ball left to find fan favourite Alex Johnston who threw a dummy to split the Bati defence close to the line.
