After 13 minutes it was 16-0.
The tries kept flowing for the green and gold, next it was Cronk’s turn. Tyson Frizell broke away down the left flank and found Cronk in support.
Mansour then picked up his second for the night after Maloney strolled through some paper-thin defence to find Moylan, who then offloaded to his Penrith teammate.
Danny Brough grubbered in and Ryan Brierley read it brilliantly to dive over to score.
The first half finished with the Kangaroos in control 30-6.
Josh Dugan opened the scoring in the second half with an impressive run from 50 minutes out.
The conversion took the score to 36-12.
But the Kangaroos went up another gear to score twice more, Tyson Frizzel and Michael Morgan grabbing tries.
