Australian Masters scorecard
UPDATE: Veteran Peter Senior has won the Australian Masters at Huntingdale, his third Masters win.
Andrew Evans was within sight on the final hole, needing a birdie to force a playoff. But he couldn't make the putt and Senior kept the outright lead, and the victory, at eight under. 
Evans fell to a three-way tie for second at six under, with John Senden and American amateur Bryson DeChambeau.
Senior, 56, has won the Australian Masters twice before, both times in the 1990s.
Earlier, Adam Scott's pursuit of a third gold jacket and his first win this year is all but over after the world No.12 finished an up-and-down final round at four-under and five shots behind the leader.
The 35-year-old is the clubhouse leader at four-under, but it is unlikely that number will stand with six players on the course ahead of Scott.
The two-time Australian Masters champion carded a two-under round of 69 that could have been much more had it not been from a couple of mistakes.
Scott made two birdies in the first five holes, but then had a double-bogey 7 on the par 5 7th.
He then turned into the back nine and made two birdies on the 11th, and 14th - the last of which took him to five-under.
At that stage, the US Masters winner was just two shots off the lead with a chance to post a score that would have put pressure on the leaders down the stretch.
However Scott immediately gave a shot back after finding the bunker at the par three 15th and then failing to get up and down.
