Mitch Marsh and Nathan Lyon led Australia to a 177-run victory over the West Indies and wrapped up a series win on day four of the Boxing Day Test.
Australia captain Steve Smith declared at 179-3 before the start of play at the MCG on Tuesday, having himself reached 70 not out, giving the hosts a lead of 459.
Medium-pacer Marsh (4-61) took four wickets to slice through the Windies, while off-spinner Lyon (3-85) also enjoyed another great day with the ball.
Overall, the Windies put in a better shift with the bat than during their woeful defeat by an innings and 212 runs in Hobart earlier this month, captain Jason Holder and Denesh Ramdin leading the resistance.
But boasting a considerable buffer courtesy of their proficient efforts with the bat, the Australian attack had only to remain patient and wait for the wickets to fall.
Kraigg Brathwaite (31) went in the 12th over, when he edged a superb Lyon delivery to Smith.
Brathwaite's fellow opener Rajendra Chandrika (37) formed a stubborn partnership with Darren Bravo, but the latter's stand, having made 81 in the first innings and 108 in Tasmania, would prove much shorter than his previous two, as he was dismissed by Peter Siddle (1-35) for just 21 runs off 61 balls.
Chandrika lasted another five overs, as Pattinson got the first of his two wickets for the innings, before Marsh removed his first victim in the form of Marlon Samuels (19), who edged the ball to wicketkeeper Peter Nevill, leaving the visitors 118-4.
Lyon got his second just before lunch when he trapped Jermaine Blackwood (20) lbw.
West Indies captain Holder (68) arrived at the crease with the score at 150-5 and showed tremendous patience and leadership under pressure to form a 100-run partnership with Ramdin (59).
Their stand ended when Marsh claimed his second scalp, as Ramdin edged behind to Nevill, before Carlos Brathwaite (2) was beaten by another lovely Lyon delivery which forced the batsman into the wrong line of defence, the ball evading the bat and brushing the bails to deliver Lyon's third of the innings and seventh for the match.
Holder's brave resistance ended shortly after as Marsh struck again, the tourists' skipper attempting to drive a full delivery on off stump and picking out Josh Hazlewood at mid-off.
From there the Windies crumbled, as the last two wickets fell for just 14 runs.
David Warner caught Kemar Roach (11) off James Pattinson (2-49) before the bowler finished the game in the outfield with an extraordinary catch after Jerome Taylor (0) attempted to slog a Marsh ball into the stands.
The third and final Test begins in Sydney on Sunday.
