Avril Lavigne has been brushing up on her surfing skills in Australia.

The 'What The Hell' singer - who is currently dating 'The Hills' hunk Brody Jenner - is promoting her latest album 'Goodbye Lullaby' in the country but has managed to find time for surfing and visiting Sydney's famous Taronga Zoo.

She wrote on her twitter page: "Omg just went to the zoo and got to touch koala bears and kangaroos!!!!! Now about to go surfing in Australia!!!!! Wow! (sic)"

She later added: "Just surfed on a 4 ft wave on a 7ft board in manly OZ. My smallest board and biggest wave to date !!! I'm tired now haha. Gonna upload WTH.TV soon of me surfing :) (sic)"

Avril has even had time to sample some of the local food, tweeting Brody's stepsister Kim Kardashian a picture of Tim Tams - an Australian chocolate biscuit snack - and writing: "I actually had some waiting for me in my hotel room.... Ur right.. Pretty good (sic)."

Avril has previously revealed she became interested in surfing because it is similar to her first love, skateboarding, which she practises in her garage.

The 'Sk8er Boi' singer said: "I sometimes skateboard at my house. This might sound really strange and bizarre, but I skateboard in my garage.

"I've started surfboarding a little bit. Surfboarding is like skateboarding, only there's a longer board."
