A beloved NSW lifeguard has drowned during a team exercise, despite his devastated colleagues' efforts revive him.
Dale Laverty was participating in a professional exercise at Nobbys Beach in Newcastle about 8am on Friday when he experienced a medical episode in the water, Newcastle City chief executive Jeremy Bath told AAP.
His colleagues pulled him from the water and worked to revive him until paramedics arrived.
The 57-year-old was taken to John Hunter Hospital but later died.
Mr Laverty was a popular member of the both the Newcastle and Lake Macquarie lifeguard teams, Mr Bath said.
"Both Councils are working with their teams who understandably devastated by Dale's death," Mr Bath said.
"We extend our deepest sympathies to Dale's family and are offering support to employees."
NSW Police in a statement on Friday also said they would look into the circumstances surrounding Mr Laverty's death.
