Beaches reopen after NSW shark attack

Beaches around Ballina on the NSW north coast have reopened following a fatal shark attack and shark sightings.

The beaches have been closed for six days since Tadashi Nakahara, 41, was bitten and killed by a 3-4m great white while surfing at Shelly Beach on Monday.

Since then, shark sightings and a large number of baitfish in the area have kept beaches closed.

It's believed the last shark sighting was at Lighthouse Beach on Friday.

Police and local lifesavers have reassessed the situation and opened the beaches between South Ballina and Lennox Heads.
