Jason Day has signed on to play this year’s Australian Open, joining world No.1 and defending champion Rory McIlroy.

Jason Day will join world No.1 and defending champion Rory McIlroy in a star-studded field for this year’s Australian Open in Sydney.

The 26-year-old Queenslander on Tuesday confirmed he’ll be back to contest the $1.25 million event at the The Australian Golf Club from November 27-30.

Day finished in a tie for sixth in last year’s tournament at Royal Sydney Golf Club in what was his first Open appearance since 2011.

“It’s always good to come home to Australia and I’m excited to be able to play at the Emirates Australian Open again in November,” he said in a statement.

“I’m excited about being fit and healthy for the Open and look forward to competing against such a tremendous field.”

Golf Australia chief executive Stephen Pitt said he delighted to have Day return to Australia this summer and fight for his first national Open title.

Day finished in a tie for 15th alongside countryman Adam Scott at last week’s PGA Championship, which McIlroy won by a single shot.
