The Australian PGA Championship will extend into Monday after heavy showers stopped play midway through the final round at Coolum on Sunday.
Play was halted at 10.58am when the Coolum course became unplayable, and even if players make it back onto the course, there's not enough time or daylight remaining for them to complete their final rounds.
Veteran Peter Senior at 12-under-par was one shot ahead of Peter Fowler and American Bobby Gates before the heavens opened and flooded several greens and bunkers.
Fairways were also starting to pool water when the siren sounded calling players off the course.
It's expected officials will announce a 6am start on Monday morning for the 24 players unable to complete their final round.
Victorian Marc Leishman (66) was the clubhouse leader on seven-under-par.
The last time a major Australian tournament extended into Monday was at the 1987 Australian Open at Royal Melbourne won by Greg Norman.
