Sydney - World number three Jordan Spieth confirmed on Tuesday he will defend his title at the Australian Open this year, an event that helped kick-start his career.
The American, fresh off his 10th US PGA Tour victory at the Travelers Championship last month, said it was a tournament close to his heart, having won twice.
"I look back at the win in 2014 at The Australian, which is a great memory, and it definitely helped build momentum for a successful 2015," he said in a statement issued through organisers.
"After coming so close again in 2015, it was great to get the Stonehaven Cup back last year. It should be a great test again - I can't wait."
Spieth claimed the tournament by six shots in late 2014, a victory that set him up for his breakthrough year where he won the first two majors of 2015.
He returned in 2015 when he narrowly missed a playoff, finishing tied-second with Adam Scott, a shot behind winner Matt Jones, before lifting the trophy once again last year.
The tournament is at the Australian Golf Club in Sydney from November 23-26.
