Launceston's Kiara Mills, 15, and Charlie Sebastian, 16, fly out for the international competition on Wednesday with fighters from Germany, New Zealand and Papua New Guinea set to be a part of the 450-strong fleet.

Experienced boxing coach and mentor of the young duo, Graeme George, said the opportunity is one unlike anything they've encountered before.

"Just to be selected to go is a big thing in itself and these two girls have won the right to represent Tasmania," he said.

"It's the biggest tournament they've been involved in for sure. We've had club tournaments and they've both gone really well, to be involved in an international tournament - that's a few steps up.

"We are going up with an open mind and I think they will do us proud."

The ground-breaking experience for both girls will be extra special for Kiara with boxing idol Daniel Geale set to feature in the corner for the pair, having taken a keen interest in their progress.

"Daniel has taken a really big interest in the girls and their fighting and after this he's keen to have them go up and train in Sydney with him which I'm absolutely fine with."

Kiara, who will be fighting at 48kgs, has a golden opportunity at her fingertips with the crown of international Golden Gloves champion within her reach if she can taste victory twice in Queensland.

Described by George as an "elusive boxer", Kiara is undefeated within local competition and has already been identified as a future prospect by Boxing Australia - featured in their 'futures' squad.

"I went with a school to a boxing thing and Graeme picked me up from there. Ever since I've been loving it," Kiara said.

"Every night we are in the ring and I love everything about it. Mainly the adrenaline rush it gives me."

Kiara's team-mate, Charlie, has been thrown into the deep-end with several fights against more-experienced campaigners at the 52kg mark, but is still seen as Tasmania's leading fighter in the division.

George described Charlie's style as remarkably different to Kiara's in that she is a "come forward on the front foot kind of fighter" as her team-mate prefers a more defensive approach.

"Charlie loves to get in there and have a go. At the end of the day, she's a very feared opponent."

The tournament runs from Thursday until Sunday with daily weigh-ins.
