Hatheier was told about the trapped shark by her mother, who swims in the pool every morning.
"I just picked him up and off he went, ' she laughed, joking that she hoped the courageous stunt would be enough to get her a spot on next season's 'Survivor" TV show. I just thought I would try and catch him.
"Everyone was saying, 'What do we do?' Mum even rang triple zero and the police came".
"So I herded him into the shallows and then I just sort of got on my knees".
"I thought, as long as I keep my hand near its fins it couldn't bite me; I wouldn't have grabbed it by the tail though".
She added: "He wasn't that heavy but his skin was very rough, like sandpaper". She said the shark felt like sand paper.
