Australia 4 for 598 dec (Labuschagne 204, Smith 200*, Head 99) and 2 for 182 dec (Labuschagne 104*) beat West Indies 283 (Brathwaite 64, Chanderpaul 51, Cummins 3-34, Starc 3-51) and 333 (Brathwaite 110, Chase 55, Lyon 6-128) by 164 runs
Perth: Australia have boosted their chances of appearing at next year's ICC World Test Championship final with a hard-fought 164-run victory over a gallant West Indies in Perth on Sunday.
Veteran spinner Nathan Lyon was the hero with superb fourth-innings figures of 6/128 as Australia wrapped up the first Test of the series with more than one session remaining at Perth Stadium.
The victory sees Australia boost their lead at the top of the World Test Championship standings, with Pat Cummins' side now boasting a win-percentage of 72.73 percent following their triumph.
That is some 13 percent ahead of their closest challenger in second-placed South Africa and Australia can move further ahead at the top when they host the Proteas in a three-Test series that commences later this month.
First of all they will be looking to complete a series sweep over the West Indies, who are almost out of contention of making it to the World Test Championship final after the loss in Perth.
Roston Chase (55) and Alzarri Joseph (43) provided a glimmer of hope during the middle session with a partnership of 82, but Travis Head chimed in with the key scalp of Joseph and Lyon cleaned up the tail to ensure Australia retained the Frank Worrell Trophy.
The only bad news to come from the victory for the hosts was the question marks over the fitness of Cummins, who battled quad soreness over the final two days of the match and did not bowl at all during West Indies' second innings.
Cummins will be monitored ahead of the second Test of the series in Adelaide and must be in some doubt for the contest that begins on December 8 and ahead of the three-match Test series against South Africa that starts later this month.
