Australia's Min Woo Lee has his sights set on back-to-back wins on home soil, especially if it means getting to indulge in some "petty" sibling rivalry.

The ISPS Handa Australian Open brings together three separate competitions, with the men’s and women’s events and the Australian All Abilities Championship being contested at the same time.

That means Min Woo and his sister Minjee will be battling for the spotlight in Sydney, just days after the former won his third DP World Tour title in the Australian PGA Championship.

"It would be nice if I have the winning throne for the end of the year because we’ve got a few weeks off until the new season starts," Min Woo said.

"It would be nice for both of us, I guess, to win the same week. It would be pretty crazy. We’ve won back-to-back weeks, but on the same week would be something else.

"I get a little annoyed when she wins the week after, because I got the light on me for a little bit and then four days later or like a week later, she’s holding a trophy.

"We’re happy for each other. We want to only do well and inspire kids and keep playing good golf, so it’s not that bad of a sibling rivalry, but petty… a little petty from me usually."

Minjee Lee, who won twice on the LPGA Tour in 2023, added: "I am competitive, but I don’t outwardly say it to him, but inside I want to do better, a little bit better.

"It’s always nice to come back home and play in front of a home crowd. I’m really looking forward to getting the week started.

"I haven’t played a professional event in Sydney and I don’t think I played that many amateur events here, so it’s the first time I’m looking at both the courses [The Australian and The Lakes] and they look pretty good to me so far."

In the men’s event, Poland’s Adrian Meronk will defend the title he won last year, with Ryder Cup winner Robert MacIntyre and former world number one Adam Scott also in the field. Tom McKibbin, Conor Purcell and Mark Power provide Irish interest.

"It was an amazing win for me, a great start of the new season last year," Meronk said.

"I really enjoyed it, especially playing with my childhood hero Adam Scott on Sunday and the crowds were amazing in Melbourne. I have great, great memories from last year.

"It wasn’t easy, to be honest. Everyone was against me, except like five people maybe. But I thought I did a good job with my caddie just to stay focused on my game."
