PHOTOS: Surf's Up For Zac Efron Down Under

High School Musical hottie Zac Efron was photographed surfing on Australia's Bondi Beach on Monday, looking gorgeous in his clinging red Oakley wetsuit, and RadarOnline.com has the sexy shots.

The 17 Again star, 22, honed his surfing skills with champion Australian surfer Layne Beachley as part of Oakley's Learn to Ride surfing day, a charity event to benefit the One Sight Foundation.

Efron's girlfriend Vanessa Hudgens accompanied him on the trip, but was at a nearby restaurant during the event.
