Australia's newest elite junior golf tournament teed off at Cronulla Golf Club on Monday.

A strong field took part on day one of the inaugural Junior 6s Invitational featuring 72 of Australia's best young male and female players.

Tyler Duncan led the boys event after round one, shooting a blistering five under par 64.

Local hopes Jeffrey Guan (67) and Harrison Crowe (71) were in the hunt to make the cut early on in the second round on Tuesday morning.

Reigning Australian junior boys champion Elvis Smylie was also in contention after shooting 66.

Reigning Australian junior girls champion Hyejun Park led the girls event thanks to her two under par 70. Cronulla's Charlotte Perkins was inside the cut line early in the second round.

Cassie Porter, one of Queensland's brightest young talents, was tied seventh alongside Perkins at +5.

Players are vying for multiple PGA Tour of Australasia and ALPG Tour exemptions. The 36-hole winners will be presented with the Norm Porter Memorial Trophy, with overall tournament champions earning automatic entry into the 2019 men's and women's NSW Open. The boys winner will also be eligible to play the Gippsland Super 6 Tour event.

The unique format will saw competitors play 36 holes of strokeplay on the Monday and Tuesday before the top eight girls and boys advance to 6s matchplay on Tuesday afternoon. The tournament is a hybrid of the Victorian Open and World Super 6 Perth formats.

Cronulla junior and former PGA Tour player-turned broadcaster Ewan Porter came up with the concept and is the tournament's ambassador.
