"The three kayakers did all the right things to care for the man. They had him stabilised on the rocks with his head and neck supported. They had everything under control.
"This man is very lucky these men were on the spot and had the skills to save him."
The man had been submerged for a short period and suffered shoulder, spine and head injuries.
"I'd say he can thank these young men for saving his life today," Mr Squires said.
"If they hadn't been there, the outcome could have been very different."
He said the injured man, who was airlifted to hospital, was a visitor travelling in a camper van with one other person.
