The Hunters, along with the Redcliffe Dolphins and the CQ Capras, currently sit at the bottom of the ladder, having only won a match each.
The Hunters desperately need to win matches to stay within range of the top 8 for a chance to make the finals with 16 rounds of football remaining.
The PNG side will have to shake off the loss quickly as they take on third-placed Burleigh Bears on Thursday at Pizzey Park in the Gold Coast.
The Hunters then return for three home matches against sixth-placed Townsville Blackhawks and fourth-placed Wynnum Manly Seagulls, and 11th placed Souths Logan Magpies.
