Thomson won five British Open titles in the 1950s and 1960s and is the only player since the turn of the 20th century to win golf's oldest major championship three times in a row.
He passed away at home in Melbourne surrounded by family on 20 June, according to Golf Australia.
"Golf has lost one of its great champions today," said a spokeperson from the R&A
, organizers of the British Open. "He will always be remembered in St Andrews."
Australia's former world No.1 and two-time Open champion Greg Norman said in a statement:
"I am so sorry to hear the passing of an Australian legend. There have been many individuals who have touched the game of golf, none more so than Peter Thomson in his era... He will be missed."
Compatriot and fellow World Golf Hall of Fame inductee Karrie Webb said she felt "honored" to have known Thomson, describing him as an "Aussie legend and true gentleman of the game."
The PGA of America called him a "legendary champion who represented his country with honor," adding he had earned a status as "one of the game's most beloved ambassadors."
South Africa's Gary Player, a nine-time major champion who won three Claret Jugs, said: "Peter Thomson was a truly wonderful golfer and a fine global ambassador for our game. His contribution to golf will not be forgotten."

Aged 14, with a handicap of 20, he received his first full set of clubs and a course membership. Two years later, he won the club championship.
Thomson could easily have pursued a different vocation after studying to earn a chemistry degree and writing a number of newspaper columns, but golf was always his foremost passion.
After beginning his professional career in 1949, he spent much of his time on the European circuit.
Only four other golfers in history (Harry Vardon, JH Taylor, James Braid and Tom Watson) have won as many Open Championships.
In fact, Thomson finished either first or second at the Open seven years running (1952-58) -- the longest such streak in the prestigious tournament's history.
