Thousands of people lined the streets of Albany on Saturday for a series of events marking 100 years since the departure of the Anzac fleet to to fight in World War One.
Twitter and other social media outlets lit up with pictures of the Troop March which got under way at 9am.
Among those taking part in the parade were representatives of the Australian and New Zealand Defence Forces and veterans.
The Prime Ministers of Australia and New Zealand, Tony Abbott and John Key, Governor-General Sir Peter Cosgrove and West Australian Premier Colin Barnett were among the dignitaries looking on.
The Premier told 6PR Radio "there are huge crowds and a wonderful atmosphere and it is a wonderful tribute to the first Anzacs who departed Albany in a 40 ship convoy 100 years ago to the day."
Following the Troop March a commemorative service was held in Anzac Park on the edge of the harbour.
Prime Minister Tony Abbott addressed the crowd of 40,000 people saying the Anzacs sacrifice "had been on a stupendous scale - a sacrifice shared by New Zealand."
He told the crowd that while the WWI Anzacs were all gone now they would not be forgotten by the nation they shaped.
A re-enactment of the WWI fleet leaving Albany will take place around 1pm. At the same time the new National Anzac Centre on Forts Road overlooking King George Sound will be officially opened.
Security was tight for the commemorations and the town was packed. Its normal population of around 36,000 swollen by an estimated 70,000 visitors.
