Peter Senior has again proven age is no barrier by storming home to win the Australian Masters 20 years after winning his last gold jacket.

The 56-year-old held off a late challenge from unheralded Sydneysider Andrew Evans to claim his third Masters title after also winning at Huntingdale in 1991 and 1995.

Senior, who started the day with a share of third, looked home and hosed with a three-shot lead with three holes to play but then bogeyed the 17th.

However Evans also dropped a shot on the tricky par 5 hole to end a two-hole birdie run and then also bogeyed the last.

Senior finished the tournament at eight-under after his final round three-under 68.

He became the oldest player to win the Australian Masters, eclipsing the mark set by 50-year-old American Gene Littler in 1980.

Evans finished on six under, tied for second with American amateur Bryson DeChambeau and John Senden.

Adam Scott finished fifth, four shots behind Senior.
