The visitors crossed the try line after two minutes of play when leading competition points scorer Carlin Anderson crossed over to score.
The Hunters responded immediately through enforcer David Loko, who sliced through the defence to score under the posts.
Buoyed on by a vocal home crowd of 6,768, the Hunters grabbed their second four-pointer through fullback Stargroth Amean, who scored in similar fashion to the first try.
The points continued to come easy with Boas kicking a penalty followed by another try to Amean in the 29th and Willie Minoga in the 33rd.
