World No.3 Rory McIlroy will be in the field for the Emirates Australian Open in November.

The two-time major champion will headline the field alongside Masters champion Adam Scott at Royal Sydney Golf Club from November 28 to December 1.

"It is pretty much locked in place I will be playing the Australian Open in Sydney," he said.

"It's been a couple of years since I last competed in an Australian Open. I competed in 2006 when I was still an amateur and then a year later after just turning pro.

"Both were in Sydney and I've always enjoyed myself in Sydney so I am very much looking forward to returning to Royal Sydney."

On his last Australian Open appearance in 2007 McIlroy finished well down the field in a share of 59th with scores of 74, 74, 76 and 77.

McIlroy won the 2011 U.S Open at Congressional and 2012 US PGA Championship at Kiawah Island among six PGA Tour victories to date and joins World N0.4  and Masters champion Adam Scott in the field.

However, the deal struck with Destination NSW means McIlory won't be representing Northern Ireland at the World Cup of Golf in Melbourne the week before because of an exclusivity agreement set down by Destination NSW.

Destination NSW CEO, Sandra Chipchase, said “I’m delighted to confirm that World No.3 and 2012 PGA Champion, Rory McIlroy, of Northern Ireland, will play exclusively in Sydney at the 2013 Emirates Australian Open.”

“Destination NSW has entered a strategic partnership with Golf Australia to stage the Open in Sydney until 2015. We are committed to our long term vision of seeing the tournament become the premier event of its kind in the Asia Pacific region.”

Golf Australia CEO Stephen Pitt said he was thrilled to see McIlroy return to Sydney for the Emirates Australian Open.

“Rory has captured the attention of the sporting world in the last two years with his wins at the U.S Open and PGA Championship and we’re really looking forward to seeing him in action at Royal Sydney Golf Club,” Pitt said.

“The fans are in for a real treat watching Masters champion Adam Scott and Rory among those competing for the Stonehaven Cup and I’d encourage everyone to get in early when ticket sales open to make sure they’ve got a spot for what will be a huge week for Australian golf.”

PGA of Australia CEO Brian Thorburn said “The Emirates Australian Open continues to attract the world’s best players to Sydney and, on behalf of the PGA Tour of Australasia, we’re looking forward to welcoming Rory back to Australia.”

The Emirates Australian Open will be broadcast live on the Seven Network across all four days.

Tickets for the championship go on sale via Ticketek on August 28.
