It was a grueling first half with the Bombers heading into the main change leading by four goals.
The second half saw the reigning premiers put on a dominant display booting sixteen goals to two, putting fear through the rest of the competition.
Billy Barden and Albert Tipungwuti showed their class leading the way in the second half goal blitz.
