A former World Number 1 and US Masters champion, Couples has enjoyed another excellent year on the US PGA Tour, culminating in his captaincy of the victorious United States team at the Presidents Cup at Harding Park Golf Club in San Francisco.
"I am very much looking forward to playing in the Australian Open and in particular the New South Wales Golf Club which is known as one of the most beautiful links courses in the world," Couples said.
"I haven't been to Sydney for some time and look forward to visiting this magnificent city once again".
Couples last played the Australian Open in 1998 at Royal Adelaide Golf Club, which coincidentally, was also played from 3-6 December of that year.
Golf Australia CEO Stephen Pitt said he was thrilled to welcome the US Presidents Cup captain to Sydney.
"It's fantastic that Fred is able to join us at the Australian Open for the first time in more than a decade and make a welcome return to Sydney," Pitt said.
"Fred is one of the world's most popular and charismatic golfers and is a joy to watch. He is playing very well and fans will jump at the chance to see him play the spectacular NSW Golf Course at La Perouse."
