It was his second marlin - the first was a 133.4kg striped marlin caught last year - and just 6kg off a world record in the small-fry class, he said.
The Riverview School pupil, who had been fishing since he was two, caught the marlin from his grandfather Keith Scott's boat Odyssey.
Proud dad Adam Scott said Saturday's fishing started slowly so at 2.30pm they decided to make their way back towards Cape Brett.
"Then just outside the area known as Queens Buoy our plans changed. A swirl behind the lure and it was gone, Hunter grabbed the rod, hopped in the chair, pushed the drag up and the fish took to the air," Mr Scott said. "At that point we all felt a little hollow inside, we knew it was a decent black and looking at the little frame in the chair our chances were slim. We agreed not to tell him what it was at first, we didn't want to freak him out."
After a three-hour battle the young angler hit crisis point, exhausted and in tears. Running out of ideas to keep him going Mr Scott got Hunter's mum on the phone.
"I don't know what she said to him but he had a new lease of life. Ten minutes after the call the swivel broke the surface and at full reach I could finally get a wrap," he said.
