Paris Hilton wowed onlookers on an Australian beach as she frolicked in a white string bikini to promote beer.

The blonde socialite attracted a large crowd of admirers when she took a dip in Sydney’s Bondi Beach to promote a new low-carb beer Bondi Blonde.

The 25-year-old told her fans: "Hey Australia, I’m really excited to be here!"

The socialite will celebrate the New Year in the sunny city and will choose the new face of Bondi Blonde from 40 Australian hopefuls on New Year’s Day.

It has not been disclosed how much Paris is being paid for her appearances, but Bondi Blonde owner Jack Singleton revealed hiring the socialite proved costly.

He said: "She doesn’t come cheap."

Paris’ trip from Los Angeles to Sydney reportedly got off on a bumpy start, when she forgot to bring her passport.

As a result, the blonde beauty was forced to take another flight and touched down several hours later than expected.
