Two of Australia's most promising golfing talents have arrived on the sport's biggest tours, earning promotion on the same day.

Karl Vilips completed a rapid-fire rise to the PGA Tour for 2025 while Cassie Porter earned a card to play the LPGA Tour next year.

Both Vilips and Porter clinched promotion on Monday via their respective US secondary tours following the season-ending tour championships, having shot up the rankings with mid-year victories.

Vilips, a 23-year-old Stanford University graduate and former child prodigy, has played only 10 events on the men's secondary tour since turning pro in June.

Porter, 22, graduated in her second season on the LPGA Futures Tour, having turned pro at age 18.

"I am really struggling to believe it," Porter said after securing the 10th of 15 available LPGA Tour cards.

"I have dreamed about this since I was a little girl."

Vilips emerged from the men's tour championship in Indiana with the 19th of the PGA Tour cards given to the top 30 on the season's points list.

Most of his work was done well beforehand as he finished runner-up in his third tour event and then won the Utah Championship the next week after shooting 25 under par.

Vilips's rounds of 75-70-71-70 left him tied for 20th in the championship.

Vilips studied in the US on scholarships since age 11 while building his golf game and, in a successful junior career, he won the 2017 Southern Amateur Championship aged 15, and the 2018 Summer Youth Olympics gold medal.

He capped a strong college golf career by winning the Pac-12 Championship in May, a result which helped earn him the partial tour status he quickly parlayed into much more.

Vilips's Australian coach for the last four years has been Col Swatton, the mentor who helped Jason Day rise to world number one.

Porter claimed a win and three top-10 finishes on the tour this season.

She finished tied 17th in the Tour Championship at Indian Wells, enough to climb one spot in the standings and crack the top 10 on the points list.
