Veterans marched around Australia marking Anzac Day with a sombre display of pride and remembrance for those who gave their lives in the major wars that convulsed the 20th century and other conflicts.

More than 1000 veterans started their march at the top of Anzac Parade against the backdrop of the Australian War Memorial in Canberra, after 32,000 people attended the dawn service in front of the national landmark.

There were more than 40,000 people at Melbourne’s dawn service, with over 10,000 others expected to take part in a march there.

In excess of 10,000 people bowed their heads at the early morning Sydney service, where 8000 serving members and veterans are expected to march.

A RAAF flyover in the nation’s capital came as onlookers cheered on the veterans who marched.

Army chaplain Phil Riley commemorated the Anzac legend on Thursday ahead of Governor-General David Hurley and New Zealand’s High Commissioner to Australia Andrew Needs laying wreaths at the Stone of Remembrance.

“At this hour, on this day, 109 years ago, the Australian and New Zealand Army Corps, at Gallipoli, made immortal the name of Anzac and established an imperishable tradition of selfless service,” the chaplain said at the dawn service.

Vice Australian Defence Force chief David Johnston asked all Australians to remember the families who mourned on Anzac Day.

“I ask you all to hold in your hearts those who mourn on Anzac Day and remember those whose service left them wounded in body, mind, or spirit,” he said.

Navy Commander Kylie Schulstad, who will reach 20 years of service this year, paid tribute to those she served with and those who came before her.

“Very proud,” her 10-year-old daughter Daisy said.

James Fry, who wore the medals of his late great grandfather who fought in New Guinea in World War II, expressed the importance of remembering the sacrifices of the men and women who served their nation.

“I always like to be here in his name,” he said.

About 3000km north of Canberra, Prime Minister Anthony Albanese finished walking the Kokoda Track with his Papua New Guinean counterpart James Marape.

Mr Albanese honoured the sacrifice of those who served along the mountainous trail, as well as those who served in other conflicts.

“Anzac Day has never asked us to exalt in the glories of war,” he said at a dawn service at the Isuvara Memorial.

“Anzac Day asks us to stand against the erosion of time and to hold on to their names, to hold on to their deeds.”

Services have also been held across the world to mark the Anzac legend borne out of two world wars.

Defence Minister Richard Marles commemorated fallen Anzacs on the shores of Gallipoli.

“When we think about the Gallipoli campaign, we think of mateship and sacrifice, and we admire the extraordinary actions of the Anzac soldiers,” he said.

Ceremonies were also held in PNG, the Solomon Islands, Thailand, Malaysia and France where Australians fought and died.

Assistant Defence Minister Matt Thistlethwaite paid tribute to the more than 2400 Australian and British servicemen killed at Sandakan and on the death marches to Ranau at a dawn service in Malaysia.

“Each Australian commemorated here served our nation during our darkest hour,” he said.

Opposition Leader Peter Dutton also paid tribute, saying Australian and New Zealand soldiers exemplified bravery, mateship and endurance.

“On this sacred day, we honour the memories of the more than 103,000 Australians who made the ultimate sacrifice,” he said.

Australia’s freedom and prosperity came off the back of what the Anzacs fought for, opposition defence spokesman and former soldier Andrew Hastie said.

“This Anzac Day, we remember and honour the brave soldiers, sailors and airmen who have defended Australia in war and peace, and those who continue to do so,” he said.
