A 33-year-old man was taken to hospital with hypothermia this afternoon after coming off his jetski at Blacksmiths Beach.
The man was riding his jetski over waves about 500 metres north of the surf club when he unexpectedly come of the watercraft.
Witnesses said he was in the water for more than an hour when nearby surfers went to his aid.
Some said it was unclear he was in distress because he appeared to be swimming around.
Surf Club members from nearby Redhead and Swansea Belmont surf clubs helped rescue the man with rescue boats and paddle boards.
The man was taken up the beach by quad bike and then in an ambulance to hospital.
He was reported to be in a stable condition.
The Westpac Rescue Helicopter Service was also called to help with the rescue.
The helicopter was then called to Elizabeth Beach near Forster to help an ocean swimmer in distress.
The Westpac Rescue Helicopter Service has now been called to Nambucca Heads where there are reports a board rider has gone missing in the surf.
Emergency services have found the board rider’s surf board in the water but there is no sight of them.
The chopper was earlier called to Elizabeth Beach Forster where it was to help a woman participating in an ocean swim who suffered a heart attack.
