Australian golfer Greg Chalmers competing on the PGA Tour.
Gregory John Chalmers was born in Sydney, Australia, on 11 October 1973 and is associated with Perth, Western Australia, where he developed as a golfer. A left-hander, he turned professional in 1995 after notable amateur achievements including the 1994 French Amateur, the Nedlands Masters, the Western Australia Championship and representation for Australia at the 1995 Eisenhower Trophy. He established himself on the PGA Tour of Australasia before progressing to the European Tour, the Nationwide Tour and the PGA TOUR. Chalmers became known for his reliable putting, resilience and strong record in major Australian events. His career highlights include two Australian Open victories, the 2014 Australian PGA Championship and a breakthrough PGA TOUR win at the 2016 Barracuda Championship. His most recent professional context is PGA TOUR Champions, where he has competed during the 2026 season.
Chalmers' first major professional breakthrough came with victory in the 1997 ANZ Players Championship on the PGA Tour of Australasia. His international breakthrough followed when he finished third in the 1997 Challenge Tour rankings, securing European Tour playing privileges for 1998.
Key verified highlights include five PGA Tour of Australasia victories, two Australian Open titles, one PGA TOUR title and a third-place finish at the 2023 KitchenAid Senior PGA Championship. He was also the PGA Tour of Australasia Rookie of the Year in 1995 and won the tour's Order of Merit in 2011 and 2014. The 2016 Barracuda Championship was his first PGA TOUR victory, achieved in his 386th PGA TOUR start.
Chalmers won the 1998 Australian Open at Royal Adelaide and captured the championship again in 2011 at The Lakes, becoming a two-time winner of Australia's national open. His most defining international moment came at the 2016 Barracuda Championship, where he eagled the final hole to win by six Stableford points in his 386th PGA TOUR start. The victory ended the longest active winless streak on the American main tour at that time and earned him a two-year PGA TOUR exemption.
