Daly pulled out of the Coolum tournament and the Australian Open in September citing a rib injury but has recovered sooner than expected.
The American golfer, who threw a putter in the lake on the 18th hole during the 2002 tournament, apologised for the confusion over whether or not he would make it to Australia.
"My recovery from stem cell surgery has been closely monitored by my doctor and I have been cleared to begin playing competitively in two weeks," he said.
"As such, I have added The Viking Classic to my 2009 US schedule plus have accepted invitations to play in the 2009 Australian Open and 2009 Australian PGA Championship.
"I'm relieved things have begun moving in the right direction.
"I look forward to returning to Australia and am grateful the Australian Open and Australian PGA Championship have provided me with the opportunity to play in these premier events."
Daly won the US PGA Championship in 1991 and the British Open in 1995 and remains one of world sport’s great characters and most popular players.
It will be the second consecutive year that Daly has played in both the Australian Open and the Australian PGA Championship presented by Coca-Cola.
Golf Australia CEO Stephen Pitt said golf fans would appreciate Daly’s presence.
“It is fantastic to see him back for a second consecutive year and I wish him well as he continues his recovery,” Pitt said.
Max Garske, CEO of the PGA of Australia agreed.
“This is great news for Aussie golf fans," he said.
“We are delighted that John has had such a successful recovery from his injury and are as pleased as he is that he is returning for our tour events.”
Daly will be joined on the Sunshine Coast by a stellar feiled including Fijian Major winner Vijay Singh, returning to Australia for the first time since 1998, and defending champion Geoff Ogilvy for the Australian PGA Championship presented by Coca-Cola.
