Captain Aaron Finch doubts Cameron Green can force his way into Australia's T20 World Cup squad, even if he dazzles in two warm-up games against West Indies this week.
Green was not included when Australia picked their 15-man group five weeks ago.
The impressive form of the 23-year-old since that selection has caught the eye, with two half-centuries in three innings against India last month showcasing his attacking talent.
Yet Finch sees his squad as being settled, with Mitchell Marsh and Marcus Stoinis on the way back to full fitness after respective ankle and side strain injuries.
Asked about Green's prospects of playing in the tournament, Finch said: "I'm not sure at the moment – I don't think so."
This is not to say Finch cannot see Green contributing immensely to Australia in the short and long term, but the World Cup decision has been taken.
"It's just one of those things," said Finch. "He had a really good tour of India, it was good for him to get an opportunity to open the batting, so he'll get more opportunities.
"He'll get an opportunity at some point in this series. The reason we've carried him is to have an extra bowling resource as well.
"Obviously his batting is exceptional, and he shows a lot with the ball. He keeps developing and he keeps improving every time he gets an opportunity."
David Warner and Mitchell Starc have returned to the Australia ranks after missing the short India series.
Australia have won two of their last three men's T20Is against West Indies (L1), including an eight-wicket victory in their most recent meeting last November.
Wednesday's series opener in Carrara will be the fourth men's T20I between the teams in Australia, and the first since West Indies won the last such game in February 2013, having been beaten in their previous two against the hosts.
Finch, Hazlewood, Cottrell closing on landmarks
There is a landmark for Finch to chase, since he is 85 away from becoming the sixth player to score 3,000 runs in men's T20I history and the first from Australia.
The skipper has struggled against the Windies, however, averaging 19.5 in eight previous T20I innings, with a high score of 53 against the Caribbean side.
West Indies have been pushed into a World Cup squad change after batter Shimron Hetmyer failed to make his intended flight, with Shamarh Brooks promoted to take his place.
Brooks is not yet in Australia, where the coming games will see a pace bowler from each side look to reach 50 wickets in T20I matches.
Australia's Josh Hazlewood is on 49, putting him one away from becoming the third Australian man to reach 50 wickets in the short format, after Adam Zampa and Mitchell Starc.
Wednesday's game will be Hazlewood's 34th T20I, and only three quicks have reached 50 wickets in fewer matches: Mark Adair, in 28 matches for Ireland; and Mustafizur Rahman, who reached the mark in 33 games for Bangladesh.
West Indies' Sheldon Cottrell has 48 wickets in the format to date, two short of becoming the fourth men's West Indies bowler to take 50, following Dwayne Bravo, Samuel Badree and Sunil Narine.
