Prince Harry has paid a surprise visit to an SAS base in Perth to honour special forces soldiers killed in the line of duty.
As part of his 36-hour whistle-stop tour, the 29-year-old royal joined the families of fallen members of the Special Air Service Regiment to lay wreaths in the Garden of Reflection at the unit's Campbell Barracks in Perth.
The SASR's commanding officer, whose identity was only given as "Lieutenant Colonel G", said: "It has been 10 years since Prince Harry last visited Australia and we are humbled and grateful that he has made the time to join us.
"Prince Harry knows what it means to serve his nation on operations and most importantly what it means to the families of those serving."
Prince Harry was a hit with the younger generation as he arrived in Australia for his first official visit to represent the Queen at the International Fleet Review, which features around 40 warships from 17 countries.
Prince Harry was greeted by thousands of well-wishers in Sydney as he represented the Queen at the International Fleet Review. The younger prince proved especially popular with the assembled young women in the crowd.
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.
