More than 101 years since Australian and New Zealand soldiers landed on the beaches of Gallipoli, their sacrifices have been remembered in parades across the nation.
Parades have drawn thousands in Australia's major cities.
Canberra
Prime Minister Malcolm Turnbull says Australia, New Zealand and Turkey remain joined in a new battle against terrorism more than a century after the Gallipoli landings.
Mr Turnbul past and present at the national Anzac Day service in Canberra.
"Today we offer our solidarity to the Turkish people as we and our allies battle together a new war against terrorism," he told the gathering at the Australian War Memorial on Monday," he said.
"This day does not commemorate a triumph of arms.
"It commemorates the triumph of the human spirit, the courage and resolve of those women who 100 years ago and ever since, and today put their lives on the line."
The prime minister also used the speech to touch on a family service record, including wife Lucy's pilot grandfather and his own grandfather Fred Turnbull who served on the Western Front.

Sydney
Feather headdresses and marching bands have attracted plenty of attention at the Anzac Day parade in Sydney but it was often the oldest gentlemen walking alone or pushed in a wheelchair who received the loudest applause.
Sydney locals and visitors have turned out by their thousands to honour past and present servicemen and servicewomen on Monday, which marks the 101st anniversary of the Australian soldiers' first landing at Gallipoli.
Onlookers lined Elizabeth Street in the CBD, waving hands and flags while dozens of military, family and community groups marched.
When elderly veterans passed by, members of the crowd could be heard shouting, "thank you".
Among the veterans was Jack Brightwell, an artillery surveyor during World War II.
Asked why he thought it important to participate in the parade he said: "I think solidarity within the community is necessary.
There's plenty of evil things out there."
Cadets have marched with the Australian flag at the start of the Anzac commemoration ceremony at Sydney's Hyde Park.
The service, held at the park's Anzac memorial, is one of numerous events around the city today.
RSL NSW state president Rod White urged those attending to mourn with pride, and remember with equal pride, those who served and still live.
Melbourne
Shunned when they returned home from the war, Vietnam veterans will lead Melbourne's Anzac Day parade.
Proudly donning their medals, veterans will march with their South Vietnamese counterparts at the front of the parade.
Waiting for their marching orders, veterans are catching up with old friends and remembering those who've died.
But they are proud and happy that feelings towards their time on the frontline have changed.
Alexander Roy Gunning was moved to tears as he lined up with other Vietnam War veterans and their South Vietnamese counterparts to lead the Anzac Day parade for the first time.
He served in Vietnam on three occasions working in the engine room on HMAS Yarra and well remembers enemy divers, and seamen dropping scare charges over the side of the ship.
It could "frighten the living hell out of you", he said.

Marching this year was particularly important after burying one of his navy friends just three weeks ago, he said, fighting back tears.
"It means a lot today ... it all just sinks in," he said.
About 45,000 people braved a chilly morning to pay their respects at the Dawn Service, filling the forecourt of the Shine of Remembrance and spilled out onto the lawns of the Botanic Gardens.
There was a noticeable police presence again this year, following boosted numbers last year in the wake of a foiled terror plot on the Anzac event that failed to daunt the Victorian crowds.
The march through Melbourne also drew tens of thousands who waved flags as the Vietnam and other veterans proudly marched behind their regiment banners, marking the 50th anniversary of the Battle of Long Tan.
A key chapter of Australia's military history, 108 Australian troops defeated a Viet Cong force of more than 1500 soldiers during that battle.

Brisbane
Generations of families have turned out in force for Brisbane's Anzac Day commemorations.
Children of all ages have lined the CBD streets with their families to pay tribute to soldiers past and present.
Australian Defence Force personnel have taken their position for the official start of the parade, which will continue through the city towards the Shrine of Remembrance.
Grahame Bernard Tweedale may be 94, but that has not wearied him.
The World War II veteran refused to use his wheelchair on Monday morning when he took part in the Brisbane Anzac Day parade for the 44th year in a row.
Mr Tweedale's eyes filled with tears when he spoke about what the day meant to him.
"It is about pride of unit," he said.
Mr Tweedale was one of many veterans who marched alongside serving members at the 100th consecutive Anzac Day commemorations in Queensland's capital city.
Thousands flocked to George, Adelaide and Creek streets in the CBD, with the overpasses also packed, to pay their respects to those who dedicated their life to their country.
Some brought chairs and ladders to sit on, while most stood for three hours to honour the men and women who walked past them in the breezy conditions.
A brief shower did not dampen their spirits, with the sunshine soon returning.
Official attendance figures are yet to be finalised, but most of the parade was cheered on by a crowd of three deep with many yelling "thank you" as the veterans passed by.

Adelaide
About 6000 military veterans and current servicemen and women will take part in this year's Anzac Day parade in Adelaide.
The journey will take them from the War Memorial on North Terrace to the Cross of Sacrifice in warm and sunny weather this year.
A large crowd is expected to watch them pass after more than 8000 attended the traditional dawn service to kick off the Anzac Day services.
After last year's centenary of the Gallipoli campaign, this year marks the 50th anniversary of the battle of Long Tan during the Vietnam War where Australian forces won a significant victory despite being heavily outnumbered.
A number of Vietnam veterans will take part in the Adelaide parade including former members of the signals corp who played a key role in the Long Tan campaign.
Perth
Maureen Hepburn has a good reason for attending the Anzac Day parade in Perth every year - her 86-year-old husband is always marching.
"It's wonderful to remember people who have served after all this time," she told AAP.
Colin Hepburn fought in the Korean War and kept his grandson and 10-year-old great-grandson by his side during the parade, while Ms Hepburn watched on as the rain poured down heavily at times.
Sydney couple, Bill and Nicole, are visiting Perth with their children, four-year-old Madison and almost two-year-old Ethan.
With Madison perched on his shoulders trying to see over all the umbrellas, Bill says simply: "Anzac Day celebrates all the services - it is the day for them when they don't have to worry about what they do every other day."

Both Bill and Nicole had grandfathers who served in WWII, and her brother is currently with the army.
Craig Bullas brings his four children, aged 10 to 16, to the dawn service and parade every year.
The family had relatives who fought for the British and German sides during WWII.
Everyone at the parade seemed to agree that the rain - which lasted more than half an hour at the start of the parade - could not dampen their spirits and standing under an umbrella or in raincoats was the least they could do to honour the Anzac spirit.
About 6500 people took part in the parade, including a group of veterans from East Timor after they and former prime minister
Xanana Gusmao were invited by RSL WA president Graham Edwards.
There is a strong connection between WA veterans and their Timorese counterparts going back to WWII when the Timorese supported Australian troops deployed in the rugged high country of Timor in 1942.
Among the oldest people in the parade were 106-year-old Eric Roediger, who was a prisoner of war and worked on the Burma-Thailand Railway, and 102-year-old Anne Leach, who was a WWII nurse.
