Some have questioned Smith's ability to continue contending on the sport's biggest stages, fearing the 2022 Open champion may have lost his competitive edge while only playing sparingly and against limited fields over 54 holes.

Scott, though, says it would be foolish to write off the World No.5 who has a supreme record at Augusta National.

"He's in the prime of his career at the moment, as far as we can tell," Scott said ahead of his own 22nd Masters tilt that will also mark 10 years since he became the first Australian to win the famous green jacket.

"His confidence has to be high, he's the reigning Open champion and coming off the year he had last year, even with if you want to call it limited preparation, it takes a lot more than that for the confidence to fade.

"So if he gets any kind of good feeling going next week, absolutely (he can win).

"And he's played great there the last few years."

Smith will round out his Masters preparation this weekend at the three-round LIV Golf International Orlando in Florida.

"Even with if you want to call it limited preparation, it takes a lot more than that for the confidence to fade." - Adam Scott. 

Former Tour pro turned analyst Brandel Chamblee says that's no way to prepare for the Masters, and also doubts the likes of former World No.1 Dustin Johnson and fellow major winners and LIV members Bryson DeChambeau and Brooks Koepka will be sufficiently ready.

"You cannot convince me that week in and week out playing against the very best players in the very best competitions doesn't make you sharper," Chamblee said earlier this month.

"Think where they are going to be a week before the Masters, typically the best players in the world in the week before the Masters go in, get a sense of how the golf course is playing and then maybe go home and practise on like conditions with like grasses.

"(The LIV players are) going to be in Orlando at Crooked Cat, putting on grainy Bermuda (grass).

"It's no way to prepare for a major championship."

But with Smith boasting ties for second, third, fifth and 10th in four of his five Masters starts, Scott believes his fellow Queenslander can rise to the occasion once again at Augusta National.

"He's got a great short game. It's so helpful there," Scott said.

"For the few times that you may find yourself out of position, when you can pitch and putt like Cam Smith, you're never out of it."
