Sutherland said ongoing travel restrictions meant holding the tournaments was not viable.
"The international element means shifting quarantine and travel restrictions wreak havoc on planning and, with our marquee players living abroad, the challenge is even greater," Sutherland said. "The pressure and risk on host venues and organisers is also high — these are small businesses who have already faced huge disruption due to the pandemic."
The 2022 men's Australian Open is scheduled to be held at Victoria Golf Club in Melbourne in November-December of next year, before returning to The Australian in 2023.
The Australian PGA Championship is scheduled to be played from January 13-16 at Royal Queensland, likely with few international players.
