Britain's Prince Harry has glided through Sydney's harbor on board a navy ship to help celebrate the centenary of the fledgling Australian navy fleet's first visit to the waterway.

Thousands of people crowded the shoreline on Saturday to catch a glimpse of royalty and celebrate the International Fleet Review. The event commemorates the arrival of the original Royal Australian Navy fleet a century ago.

Dozens of warships from 17 nations are in Sydney this weekend for the fleet review.

Harry is in Australia's largest city for just one day as part of a quick trip Down Under. He flies to the Western Australia state capital, Perth, on Sunday before leaving the country.
