Australia captain James Tedesco scored two tries as the Kangaroos cruised to their 12th Rugby League World Cup crown with a 30-10 victory over Samoa on Saturday.

The Australians had little difficulty in sweeping aside their opponents, who were playing in their first final after beating hosts England to reach the trophy match.

Latrell Mitchell crashed over after 14 minutes before Tedesco and Liam Martin – the latter after a video review – added tries in a prosperous first half for Australia at Old Trafford.

Nathan Cleary only added the extras to one of those first-half tries, though, before Angus Crichton was fortunate to only be sin-binned for a high tackle on Chanel Harris-Tavita after the interval.

Cleary found Cameron Murray to extend 12-man Australia's lead before a delicate Josh Addo-Carr kick teed up Crichton, though the video referee ruled out the try after the latter failed to ground the ball.

Brian To'o finally responded for Samoa with 20 minutes remaining, but any hopes of a fightback were stifled when Tedesco broke through for his second score.

Stephen Crichton managed a late consolation before Mitchell bundled over for his second try, as Australia eased to a 19th straight World Cup match win on English soil to secure more silverware.
