Held in Sydney Australia to commemorate 100 years of Navy.

On 4th October 1913, a fleet of 5 ships entered Sydney Harbour to show to the Australian public the new fleet built to Australian requirements by British boat builders.

An estimated 1.7Million people attended the event around the harbour foreshores. Pretty decent attendance figures for a city of 4.5Million.
