A Greg Inglis inspired Australia have moved through to the Four Nations final after sweeping aside Samoa 44-18 in Wollongong on Sunday.
Man of the match Inglis and halfback Cooper Cronk both scored doubles in the convincing win.
Samoa had been highly competitive in their losses to England and New Zealand, but the Australians blew them off the park in the first half in an impressive five-tries-to-one effort before 18,456 fans to lead 28-6 at the break.
The contest was more even in the second half with the Kangaroos scoring three-tries-to-two, but by then the damage had been done.
Cronk opened the scoring in the second minute on the back of an Inglis bust, before the superstar fullback crossed himself in the 11th, after a series of offloads.
Inglis went over again in the 26th minute from a Cronk pass, to move to ahead of Bob Fulton to fourth on the all-time scoring list for Australia with 27 tries.
In between fullback Tim Simona opened Samoa's account when he beat Cameron Smith and Aaron Woods from close range in the 20th minute. Five-eighth Daly Cherry-Evans then added to Samoa's misery in the 31st minute when he dummied his way through their defensive line from a scrum and raced 70m to score.
A long ball from Cameron Smith put David Klemmer over for his first Test try in his second game to increase Australia's lead to 22 points
Ben Roberts gave Samoa (who needed to win by nine points or more to make the final) some hope when he danced through the Australian line in the 47th minute, only for Cronk to respond with his second in the 62nd minute.
David Fa'alogo scored for the visitors in the 69th minute before Josh Papalii boosted Australia's tally when he crashed over seven minutes later.
Josh Mansour scored his first Test try in the shadows of fulltime.
Aaron Woods was strong up front for the Kangaroos.
Josh Jackson was thrust late into the game by Australian coach Tim Sheens on his Kangaroos debut.
Australia will meet New Zealand in the tournament decider in Wellington on Saturday.
