Nico Antic, the 12-year-old boy who was mauled by a shark in Sydney Harbour, has died in hospital.

He was swimming with his friends at Nielsen Park on Sunday when he was attacked by what is thought to be a bull shark around 4.20pm.

Nico suffered serious injuries to both of his legs, and was only able to survive after the other children bravely dragged him out of the water and onto some nearby rocks.
