World number four Adam Scott will make his final appearance of the year at the Australian Open in November, organisers said Thursday.
The reigning US Masters champion has set himself a gruelling home schedule, having already agreed to play the Australian PGA Championship and defend his Australian Masters title.
He is also widely expected to play the World Cup in Melbourne, making it four tournaments in four weeks.
"Winning the national Open is the title every Australian golfer wants," Scott said in a statement.
"I am sure the Sydney sporting public will come in great numbers to support the event. I look forward to competing and celebrating with them during the week."
The Australian Open will be played at the Royal Sydney Golf Club from November 28-December 1.
