Travis Birt has severed ties with the WACA and will attempt to become a Twenty20 gun for hire.
Birt, 31, is currently playing for Khulna Royal Bengals in the Bangladesh Premier League.
The hard-hitting batsman was given permission to join the T20 franchise last month, but had to retire as a Warriors player to take up the contract.
Birt's departure will help the WACA find salary cap room to sign returning veteran Mike Hussey next season, as well as add promising young players such as Hilton Cartwright and Sam Whiteman.
Birt joined WA last season after a steady career with Tasmania that saw him win a Sheffield Shield before he was squeezed out by the emergence of players like Test prospect Alex Doolan.
He played eight shield and eight one-dayers for the Warriors last season, but had struggled for selection this season.
He added a single shield match before Christmas to finish with 3138 runs at 30.76 in 59 games for the two States.
He averaged 30.95 for 2259 runs in 83 one-dayers.
Meanwhile, his former Tasmanian teammate Ricky Ponting has put full-time retirement on hold to nominate for the lucrative Indian Premier League.
Former Australian captain Ponting, who retired from international cricket late last year, has attracted the highest reserve price of $US400,000 ($A386,000) on the auction list of 101 nominated players.
Ponting and Australian Test captain Michael Clarke are the only players with a top reserve price for the auction, to be held in Chennai on Sunday. Clarke is joined by Matthew Wade and Glenn Maxwell, who both have a reserve price of $US200,000, and Phil Hughes and Moises Henriques, whose reserves are $US100,000.
