Info from Licensor: "My dad and I were fishing 1-mile off Semaphore Beach. While fishing, I made a joke to my dad about how it'd be cool to see a shark in open waters. About 10-20 minutes later, a big great white popped up and luckily I managed to get my camera out in time. The footage is good but doesn't compensate the monsters real size. When it swam under our boat, the head was at the front and the tail of the shark came back to the end of the boat which was 5.5m long. That makes the shark 5.5 meter - 6 meters long. We had to quickly get the crab nets in and our burley to make sure it didn't get our equipment tangled. We waited for it to leave and continued fishing and crabbing. We then bagged out on blue swimmer crabs."
