More than a million people are expected to line the banks of Sydney Harbour later today to catch a glimpse of Prince Harry and commemorate 100 years since the Royal Australian Navy's (RAN) first modern warships sailed into Sydney.
The event will involve 8,000 naval personnel and Royal Australian Air Force aircraft, and will finish with a firework display over Sydney Harbour Bridge.
Britain has sent one of its latest and most advanced ships, Type 45 destroyer HMS Daring, to represent the Royal Navy.
Earlier Prince Harry embarked on survey ship HMAS Leeuwin at the city's Garden Island naval base before inspecting the flotilla at the International Fleet Review in Sydney, which features around 40 warships from 17 countries.
