A relieved Lee only secured his ticket back to the Masters at last week's WGC-Dell Technologies Match Play in Texas, where he needed to win at least one group match.
He did just that with a thrilling comeback victory over Sahith Theegala, before taking to social media to express his delight at being able to head back to "Heaven on earth" for the season's first major starting on April 6.
But while he is again taking his family along for the ride, including dual women's major winner Minjee and his golf-teaching mother Clara, Lee won't have his superstar sibling carry his bag during the traditional Masters par-three contest on tournament eve next Wednesday.
"It's either my mum or my girlfriend," Lee told AAP during a Zoom call from his Dallas base on Thursday.
"They're coming over, so it will be one of them, but not my sister this year. She got her chance to shine last year and she showed off too much, so not this time."
Lee was only half-joking, with the 24-year-old readily acknowledging Minjee as his idol, while always hungry to seize family bragging rights from the reigning US Open champ.
He briefly stole the spotlight from the world No.5 with a front-nine 30 at Augusta during last year's final round to soar to third spot, before ultimately finishing equal 14th on debut.
That breakout US performance, followed by his sixth-place finish at this month's Players Championship, has the Perth prodigy believing he can seriously contend for the green jacket.
"I knew it was going to be tough to beat him, but the first few holes I was there," Lee said of his last-round, last-group duel with world No.1 Scottie Scheffler at TPC Sawgrass.
"It's a special experience being up there in America and having a chance to win or being up there.
"For the first experiences I've had at the Players and the Masters, it was an incredible result.
"To shoot six-under on the first nine at Augusta, it was a great debut and not many people have done that, and having the equal record for the lowest nine.
"It gives me a lot of confidence knowing I can go out and shoot that number.
"Hopefully I can do it again this year."
While Lee will lean on Minjee for moral support, he also plans to tap into the vast Augusta experience of major-winning countrymen Jason Day and Adam Scott, who is celebrating the 10th anniversary of his watershed 2013 win.
"I'll probably play (a practice round) with Jason and Scotty," Lee said.
"We played at the Players. They'd won there before and it was nice to play with them - not just because I want to pick their brains, but they're great golfers and awesome guys."
Lee credits Scott's landmark triumph - which broke Australia'79-year Augusta title drought - for inspiring his own career.
"It was a fond memory and hopefully we can make another one this year," Lee said.
"It was amazing for Aussie golf and you look up and you want to be that player, I want to be Scotty.
"He's got an amazing swing and amazing demeanour, the nicest guy. It's awesome to be friends with him the last few years after looking up to him as a kid."
