Quade Cooper has signed a contract committing to the Australian Rugby Union until next year's World Cup, rejecting approaches from National Rugby League club Parramatta to switch codes.
The ARU announced the one-year contract Friday, on the eve of the last Tri-Nations test against New Zealand.
It means the 22-year-old Queensland Reds flyhalf will be available for selection at the next World Cup in New Zealand.
Cooper played a pivotal role in the Reds resurgence in Super 14s this season, making him first-choice flyhalf for Australia in a competitive inside backs division.
He will start for the first time against New Zealand here Saturday, having been suspended for Australia's two earlier losses this season to the All Blacks.
