Thousands of people have gathered in central Sydney to commemorate Anzac Day as photos of diggers are being projected onto Charles House in Sydney's Martin Place.
In Sydney, AirCommander Australia, Air Vice Marshall Steven Roberton, delivered the address lauding the original Anzacs, members of the Australian and New Zealand Army Corps at Gallipoli on April 25, 1915.
"They changed that simple acronym of their Army Corps into a word that stands for unity and mateship, courage and determination," he said.

He said the legacy of Anzac day needed to be continued, more than 100 years since the tragic landing.
"Anzac day is not about glorifying war, but about celebrating the Australian spirit, which we share with the New Zealand counterparts," he said.
"Anzac signifies strength and quality of character, attitude and action that transcends time.
"The challenge for us here this morning is to ensure that the spirit of Anzac is passed on to our children and, in so doing, honour the fallen and their sacrifice."
He acknowledged Anzac Day caused pain for many.
"For some, it is a day of grief and tragedy, of immeasurable loss and deep mourning for loved ones and mates lost in battles. But for others, this is a day of pride and of mateship."

Foreign Minister Julie Bishop, Acting Opposition Leader Tanya Plibersek, NSW Governor David Hurley were among the thousands gathered for the service.
Families with young children are among those to have come to the Cenotaph for this year's Anzac Day dawn service in the city.
Later on Wednesday, female veterans will lead the march in Sydney for the first time to mark 103 years since Anzac troops landed on the Gallipoli peninsula in 1915.
Steel bollards have been positioned along the Sydney CBD march route while CCTV and airport-style bag checks will be utilised. Uniformed and plainclothes police will patrol the streets.
In another first, RSL NSW will fundraise for the 2018 Invictus Games after president James Brown announced in 2017 the charity would stop fundraising for itself following a scandal over the misuse of funds.
The games are a Paralympic-style sporting event for wounded, injured and sick servicemen and women.
