And Australia's latest sporting superstar wasn't happy.

During his moment of basking in the glory of becoming the first Australian in 29 years to win golf's oldest and great prize, Smith was asked if he was interested in joining the Saudi-backed rebel LIV Golf Tour.

Smith snapped when the reporter said, apologetically, that he was only asking because the rumour mill was in overdrive that the 28-year-old might be signing.

"I just won the British Open, and you're asking about that. I think that's pretty not that good," Smith said, before being pressed further.

"I don't know, mate. My team around me worries about all that stuff. I'm here to win golf tournaments."

"I just won the British Open, and you're asking about that. I think that's pretty not that good." - Cam Smith.

Greg Norman, an idol of Smith's and Australia's most recent Open Champion in 1993, is the CEO and face of LIV Golf.

The billion-dollar organisation has already signed 23 players who competed in the 150th Open at St Andrews, including major winners Phil Mickelson, Brooks Koepka, Dustin Johnson, Bryson DeChambeau, Patrick Reed, Sergio Garcia and Louis Oosthuizen.

But in a huge concern to the PGA Tour, there are whispers those six heavyweights may merely be the tip of the iceberg.

Now that the 2022 major season is over, speculation is rife that a raft of big-name players are about to announce their defections as soon as this week.

Iconic players from various nations and continents are said to have been offered insane amounts of money to join LIV Golf.

Johnson was reportedly paid $US200 million ($A294m) to sign on after Tiger Woods apparently turned down a close to $US1 billion offer to join.

Among the other international stars to have been lured across are Aussie Matt Jones, Lee Westwood, Ian Poulter, Talor Gooch and 2018 Australian Open champion Abraham Ancer.
