Scott has played the Australia PGA Championship every year except two since 2000, recording seven top-10 results including a 2013 victory and 2014 runner-up finish.
“To be able to win another Joe Kirkwood Cup would be the perfect end to 2019,” he said.
“I love coming home and playing in front of Aussie crowds and they don’t get much better than at the Australian PGA Championship.”
Scott has made a solid start to the 2019 PGA tour season, recording three top-10 results in just eight starts this year.
It comes after two tumultuous years in his career wherein Scott made coaching changes, putting adjustments, and trialled playing in three-week blocks and in tournaments immediately before the four majors.
Those changes saw him struggle to qualify for the US Open in 2018 and plummet to 76th in the world rankings.
But he looks to be on his way back up in the 2019 PGA tour season, and is currently 29th in the world rankings.
“Adam Scott is one of Australia’s most loved athletes and we are delighted to have him playing the Australian PGA Championship in 2019,” said Gavin Kirkman, CEO of the PGA of Australia.
“With his father Phil being a PGA professional, I know the Australian PGA Championship has always had special meaning for Adam which is reflected in his outstanding results at the tournament.”
