Two fishermen were frozen with fear as the 4m monster circled their boat off Altona for about 10 minutes.
"He came and touched the boat about three times," Ray Theuma said.

"He was going around and around and around for about 10 minutes. He was very hungry, mate."
Experts say conditions are perfect for a big shark season, with ideal water temperatures and an abundance of bait fish.
Melbourne Aquarium's Nick Kirby said an increase in fish populations after the tightening of fishing permits could attract more sharks into the bay.
"What you've got is a temperature in the bay which is a great temperature for a cold-water animal if it wants to speed up its metabolism and have a feed," he said.
"I would suggest it's going to be a long summer given how early the temperatures have peaked."
Mr Theuma, 56, was fishing with his nephew Brian Bell about 7km off shore when they were stalked by the great white shark.
"My boat is 4.6m and the great white was approximately the same size as the boat," he said.
Mr Bell, 47, from England, took some amazing photos of the shark as it circled.
Mr Theuma, who has fished in Port Phillip for 20 years, said he feared the shark would venture closer to shore.
He was also concerned about inexperienced young people taking boats out and swimming in deep water.
"There's a lot of young people who are new to boating," said Mr Theuma, who is a member of the Altona Boating and Angling Club.
Life Saving Victoria's Guy Britt said the Westpac rescue helicopter was already patrolling on weekends.
It will be on duty daily after Christmas until Australia Day, when beachgoer numbers peak and sightings are more likely.
Mr Britt urged swimmers to take care.
Surfwatch Australia founder Michael Brown said conditions were attracting many more bait fish along the east coast, which in turn brought sharks close to shore.
He said swimmers should avoid areas with schools of fish that could attract sharks, which often sat just behind breakers.
