Two men found clinging to their broken down jetski were rescued near Bellambi Harbour on Tuesday afternoon.
Surf Life Saving IIlawarra duty officer Anthony Turner was on a surveillance patrol when he found a jetski floating 200 metres south of the harbour shortly after 5.30pm.
Mr Turner could not see anyone on the jetski and investigated further after seeing it floating 150 metres away from rocks.
Mr Turner then noticed the men clinging to the back of the broken down jetski trying to swim it further away from the rock platform.
He raised the alarm by notifying the Surf Life Saving operations centre for immediate assistance.
A Wollongong council lifeguard on a rescue water craft responded and assisted with the rescue.
The men and jetski were returned safely to Bellambi Harbour.
Mr Turner stayed with the men to check on their welfare.
They did not require any medical assistance.
Mr Turner said the men were "very grateful" for the help and praised them for their actions.
"They did everything correctly," he said. "The men did not panic and phoned a friend to alert him of the mechanical issues with a jetski.
"They also stayed with the jetski, swam further out to stay away from the point and were wearing personal flotation devices."
