The Kangaroos claimed an Ashes clean sweep after Harry Grant led Australia to victory at a sold-out Headingley in Leeds.
The visitors were forced to absorb considerable pressure early in the second half before the dummy half broke through for a crucial try in the 61st minute.
The four-pointer swung the game in the Kangaroos favour they didn't look back. Fullback Reece Walsh added two tries of his own in the final 10 minutes to secure a 30-8 victory over England.
The match was much closer than the scoreline suggested, with the hosts pulling within four at half-time and generating multiple scoring opportunities after the break.
The Kangaroos were tested but their defence was ultimately up to the task as they worked their way to a 3-0 Ashes victory.
Australian five-eighth Cameron Munster was awarded the Fulton-Reilly Medal as the player of the series.
Munster was superb in the first Test before producing a man of the match performance in the second. Munster was again instrumental in the victory at Headingley, laying on both of Australia's first-half tries.
England scored their first try since the 75th minute of the opening Test when hooker Jez Litten slid straight through the Kangaroos defensive line before dummying his way past Reece Walsh. The hooker then put the ball on the toe, with George Williams winning the race to the ball in the in-goal to score in the 33rd minute.
A Harry Grant try from dummy half midway through the second half shifted momentum Australia's way and fullback Reece Walsh scored two late tries to complete the 30-8 win.
