Ian Thorpe looks increasingly likely to forgo a tilt at this year's world swimming championships in favour of targeting next year's Commonwealth Games.

Thorpe wants to continue swimming since missing out on a spot on Australia's London Olympic team.

But with world championship trials less than three months away, Thorpe is yet to confirm whether he will attempt to win a place on Australia's team for the July/August world titles in Barcelona. Australian head coach Leigh Nugent said he was yet to speak to Thorpe.
