Earlier on the same day at noon, an 11-year-old boy was also attacked by a shark, with his surfboard being damaged, fortunately the boy escaped unharmed. The day before on the 18th in the afternoon, a 12-year-old boy jumped from rocks into the sea outside the shark net and was bitten on both legs by a shark, he is currently in critical condition in the intensive care unit at the Sydney Children's Hospital. The beaches involved have all been closed.
