Surf's Up: Zac talks to a youg female surfer in a wetsuit and shorts after flying in for a charity event sponsored by Oakley sunglasses
But perhaps the thought of hundreds of people watching in action left the actor feeling a bit of stage fright.
The Californian actor and girlfriend Vanessa Hudgens were flown Down Under by Oakley sunglasses to raise awareness for their OneSight Foundation's Learn-To-Surf programme.
While Hugdens kept a low-profile in the nearby North Bondi Italian restaurant, Efron was driven on to the beach in a golf buggy.
Stage fright: Efron leaves the surfboarding up to others
Dressed in a red Oakley wetsuit, Efron was overwhelmed by the crowds of screaming girls clambering for a photo or autograph with the heart-throb.
While Efron was happy to wade into the sea, he declined to demonstrate his surfing skills.
He was flanked by pro-surfers Layne Beachley and Tom Whitaker and a few hand-picked youngsters who were learning to surf.

Instead of 'hanging 10', Efron was happy to play teacher as he helped some of the teenagers onto the surf boards.
Sydney local Craig Gill said his four-year-old daughter Petal was smitten with the teen idol.
He told MSN Australia: 'She's the only one that got a kiss. We just happened to come down, and she's the biggest fan of Zac.'
