A man has been attacked by a shark in the Whitsundays at the Great Barrier Reef.
The man, in his 20s, was bitten on the thigh in waters at Hardy Reef, about 50km northeast of Hamilton Island about 12.30pm (AEST) on Monday.
Paramedics have winched the man to safety and will now take him to Mackay Hospital. He is in a stable condition.
It is unknown whether the man was snorkelling or diving from one of the reef's popular pontoons.
The Whitsundays region has been the site of a number of shark attacks in the last six months.
Victorian man Daniel Christidis, 33, died in November after being attacked at Cid Harbour at Whitsunday Island during a trip with friends and colleagues.
That incident followed separate attacks - also at Cid Harbour - on Tasmanian woman Justine Barwick and Victorian 12-year-old Hannah Papps within 24 hours in September.
