A woman has been captured on film picking up a one-metre shark in a Cronulla rock pool and throwing it back into the ocean.

The video of real estate agent Melissa Hatheier was posted on the Cronulla Real Estate Facebook page on Tuesday.

"Our in-house Shark Wrangler Melissa Hatheier wrestling a shark out of Oak Park Rock Pool yesterday morning! Nice work Mel!" the post read.

Ms Hatheier's daughter Shannon, 19, a law student at the University of Sydney, filmed the encounter from the side of the pool, while her sister Lani, a year 8 student, watched on.
