Australia progressed through to the semi-finals of the 2013 Rugby League World Cup, but they did so with a less than convincing second half performance.
The Australians went into the second half with a 38-point lead against the USA but were restricted to just four second half tries.
Johnathan Thurston converted all four second half scores after an indifferent first half kicking performance had seen the stand-off kick just three from eight attempts.
After Greg Inglis had crossed on 51 minutes his centre partner Jarryd Hayne scored a second half hat-trick to finish with a four-timer.
His last, a minute from the final whistle, saw Hayne cross from a Corey Parker flip pass.
Australia have an injury doubt over Billy Slater who left the field two minutes into the second half with a knee injury.
