Greg Norman will feature in the Jonnie Walker Classic in Perth, Western Australia, next February.
The former world number one, who dominated the leaderboard for most of the Open Championship at Royal Birkdale earlier this month before falling to a third-placed finish, will line up at the Vines Resort and Country Club.
The event, which takes place from February 19-22, is expected to attract further big names as it is tri-sanctioned by the European, Asian and Australasian Tours.
Norman, who was born in Queensland and is now based in Florida, said: "It will be a great treat to be competing back on home soil in Australia, especially in Perth, which offers great weather, a fantastic championship course at The Vines and a wonderful backdrop for a tournament."
The 53-year-old is the only golfer to be number one on both sides of the Atlantic, winning The European Tour Order of Merit in 1982 and topping the US PGA Tour Money List in 1986, 1990 and 1995,
He has won more than 80 tournaments worldwide including two Opens, in 1986 - the year where he led all four majors into the final round - and 1993, and spent a total of 331 weeks at the top of the official world rankings.
