Marnus Labuschagne struck an unbeaten 154 to help Australia reach 293-2 on day one of their first Test with West Indies on Wednesday.

West Indies struggled to find answers at Optus Stadium in Perth, taking only the wickets of openers David Warner (5) and Usman Khawaja (65).

Australia, who have lost just one of their past eight Test series, were in trouble early on as Warner's lean streak in the longest format continued when he chopped on from Jayden Seales' wide delivery.

The home side were 9-1 when Labuschagne arrived at the crease, but he and Khawaja set about advancing their side to 72-1 by lunch and then kicked on.

Kyle Mayers gave West Indies a much-needed breakthrough when delivering a perfect ball that caught the edge of Khawaja's bat and was gathered by Joshua Da Silva.

The Khawaja-Labuschagne partnership may have ended at 142 runs, but the latter was not finished there as he struck 16 fours and a six en route to another huge score.

Steve Smith also chipped in with an unbeaten 59 while producing a 142-run stand of his own with Labuschagne, which they will look to build on when play resumes on Thursday.

Magical Marnus

Australia are undefeated in their past 11 Test series against West Indies, winning 10 of those and each of the past eight, and they already look great value to extend that streak.

Labuschagne was undoubtedly the star of the day with his eighth Test ton and he will now look to build on his unbeaten 154, which is the fourth-highest tally of his career.

Weak Warner

West Indies have won their past two Test series and they started well in Perth when sending Warner packing in the fourth over.

That was the Australia opener's fourth successive single figure dismissal in a home Test innings, and he will be grateful that Labuschagne in particular was able to bail him out.
