Brett Morris scored four first half tries as Australia demolished USA after a good start from the Tomahawks.
Cameron Smith’s kick off hit the upright and after forcing a goal line drop out the Australians were over in their second set through Jarryd Hayne.
A good run from Sam Thaiday set up the position for Greg Inglis to score but the Tomahawks stuck to their task with half backs Joe Paulo and Craig Priestly featuring once again.
But four tries in seven minutes ended this match as a contest as Morris twice, Smith and Cronk all crossed as Australia were unstoppable down their right-hand side attack.
Morris completed his hat-trick before adding a further try from a Cooper Cronk kick.
