Valentine Holmes has scored a record five tries for the Kangaroos who have sounded an ominous warning to rival nations with a 46-0 trouncing of Samoa in their Rugby League World Cup quarter-final.
Coach Mal Meninga wanted his team to entertain on Friday night, and Australia treated the sellout 13,473 crowd in Darwin with an impressive eight-try rout to move into the final four.
The Kangaroos will move to Brisbane to face New Zealand or Fiji.
Holmes broke the Australian record for most tries in a Test, surpassing eight players on four, including teammate Wade Graham who achieved the feat two weeks ago.
Michael Morgan scored a first-half double, while Billy Slater also went on the scoresheet in what was easily Australia's best attacking display of the tournament.
