SURF Life Saving Queensland lifeguards were put through a series of fitness proficiency tests at North Stradbroke Island on Friday.
About 20 lifeguards and trainees from across south-east Queensland completed the testing at Main Beach.
All Surf Live Saving Queensland lifeguard employees are required to complete the testing, which ranges from water-based rescues to first aid and advanced resuscitation.
Surf Life Saving Queensland lifeguard supervisor Tim Wilson said the testing ensured all members of the service maintained high standards.
"Our beaches may be a little quieter this time of year, but it is essential that our lifeguards remain focussed ahead of what will no doubt be another busy season across the region's beaches," he said.
"A range of complex rescue scenarios, including board and tube rescues, tested guards' physical and mental capabilities, ensuring each maintains a high level of fitness and emergency care skills."
Mr Wilson said annual fitness proficiency testing also encouraged improvement within the service.
"Many of our lifeguards have strong affiliations with surf lifesaving clubs, having begun as nippers, junior or senior surf lifesavers," he said.
"While SLSQ boasts around 50 permanent lifeguards across the state, we also employ part-time and casual guards, each dedicated to saving lives and protecting beachgoers along the state's coastline."
Surf Life Saving Queensland lifeguards saved 2,513 people through in-water rescues and administered 42,159 first aid treatments in 2018/19.
