A teenager has been attacked by a shark while spearfishing off the Northern Territory coast.

The 17-year-old was bitten on his arm and leg about 30km offshore from Nhulunbuy in Arnhem Land on Sunday morning, NT police said.

He was treated by paramedics who reached his vessel with police, before being taken to hospital in Gove.

The boy was later airlifted to Royal Darwin hospital suffering "deep lacerations", a Careflight spokesman said.

The ABC reported that authorities believe the teenager was bitten by a reef shark.

Sunday's attack comes after a man was airlifted to hospital after a shark bit him at a beach south of Wollongong on Saturday.

The 24-year-old from Sydney was attacked about 1pm on Saturday at Seven Mile beach at Gerroa while learning how to surf.

He was treated at the scene before being airlifted to St George hospital for wounds to his hand and calf.

The beach was closed on Saturday while police investigated the incident along with Surf Life Saving and the Department of Primary Industries.
