Warships from 17 nations including the United States and China have been welcomed in Sydney Harbor as the city celebrates the centenary of the fledgling Australian navy fleet's first visit.

Thousands of spectators lined the harbor shores under blue skies on Friday to watch the warships power into Australia's largest city.

Seven Australian warships entered the harbor in line as the first Australian navy fleet of seven cruisers and destroyers did for the first time on Oct. 4, 1913.

Around 40 warships plus 16 tall ships will participate in the International Fleet Review on Saturday which is the main event commemorating the arrival of the original Royal Australian Navy fleet a century ago.
