Captain of the West Indies, Shai Hope, says they need to build on the positives from the first two T20 internationals against Australia for the third match in St. Kitts on July 25.
Australia lead the series 2-0 following an eight-wicket win in the second match at Sabina Park, on Tuesday.
In the first match, Hope and Roston Chase made a half century each and shared in a 91-runs second wicket partnership.
Meanwhile, the bowlers had the tourists struggling on 78 for 4 after nine overs before Cameron Green and Mitch Owen shared in an 80-runs fifth wicket partnership to strengthen the innings.
In the second match Brandon King made a half century, while Andre Russell made 36.
Hope says the Caribbean side need to build on their strong starts.
