The footage, posted on Cronulla Real Estate's Facebook page, shows Melissa Hatheier picking the young shark up and tossing it back into the ocean. "I then grabbed him around the neck so he couldn't swing around and bite me", she explained.
"I jumped in and I thought, 'I reckon I can probably get him out.' And Mum, god love her, called 000 so the police came down as well", Hatheier recalled.
The crowd of onlookers cheered after she tossed the shark into the ocean, to which she raised her arms in triumph. And they didn't know what to do.
Her intervention, filmed by her daughter on a mobile phone, has turned Ms Hatheier into an internet sensation after video of the shark's removal went viral.
Sydney resident Melissa Hatheier was swimming in a bay near Melbourne, when she stumbled upon a shark.
"As a real estate agent I'm used to relocating people and this was similar". I started to swim around him and he became a bit stressed and started to knock his head on the rocks.
She added, "I was thinking I just need to put him back where he is meant to be". "With his fins, I picked him up and helped him back".
