The attack occurred off Shelly and Emerald beaches in Coffs Harbour, about 530 kilometers (330 miles) north of Sydney.
Witness Aaron Armstrong said Emerald Beach was very popular and many locals were in the water enjoying and celebrating Fatherâs Day. âYeah, it will change the fabric a little bit for a little while in EB, thatâs for sure,â Armstrong told Australian Broadcasting Corp.
He said it was the first shark attack in the community that he and other locals knew of.
New South Wales state is under a coronavirus lockdown but people can leave their homes for exercise, including swimming. People from the same family can go to the beach for Fatherâs Day.
Before Sunday, the most recent fatal shark attack in Australia was in May off the coast of Forster, 220 kilometers (137 miles) north of Sydney.
