The 10-year-old St Marys fisher caught a 97-kilogram mako shark on a 15-kilogram line off the St Helens shelf in last Saturday's St Helens Game Fishing Club shark competition.

The catch was so big, it is a pending Tasmanian and Australian record for a small fry female.

It took Zara 55 minutes to land the mako and she already holds two small fry national records - a 5.2kg albacore on 4kg line and 24.5kg bluefin tuna on 24kg line.

Club vice-president Jason McGiveron said Zara had been game fishing for the past three years.

"Last year they actually separated the male and female record categories, so a lot of the records were opened up," Mr McGiveron said.

"It has really promoted the sport a lot."

Two other junior records are also pending from the competition, where 20 sharks were tagged and released.

Northern Game Fishing Club fisher Chloe Hamesley, 12, caught a 106kg mako on 37kg line to set a new state record and Jaiden Walker caught a 44kg blue shark on 8kg line to create a Tasmanian and Australian record.

Simon Clifford reeled in the heaviest fished of the competition - a 107kg mako shark.
