And across the Tasman, rain could not deter thousands from gathering at the cenotaph in Auckland Domain for New Zealand's biggest dawn service.
In Canberra, Victoria Cross winner Corporal Ben Roberts-Smith made a moving tribute to one of his fallen mates, reciting the words of the teenaged son of Matthew Locke, killed in action in Afghanistan's Chora Valley in 2007.
"Whenever something challenges me and I think of giving up I can feel dad looking down on me cheering me on. His death left a hole in my heart but his spirit has given me the motivation to push myself further than ever before," wrote Keegan Locke.
Like many dawn services around the country, the service at the Australian War Memorial featured some innovations, among them readings of accounts of Afghanistan by Australian servicemen and their families.
The names of iconic Australian battles were flashed onto the side of the Memorial building, and images of Australian men and women taken in more than a century of conflict.
A video featuring Australian diggers fighting at the Somme in France during World War I was played in Adelaide, marking a departure from the traditional service that has been attended by growing crowds in recent years.
Tim Barrett, Commander Australian Fleet, told the thousands packed into Martin Place in Sydney the Anzac spirit continued to inspire Australian servicemen and women in current conflicts across the world.
"It is this Anzac spirit that shows us not who we are intrinsically as Australians but who we want to be as a nation," he said.
Vietnam veteran Col Kelson has attended the dawn service in Sydney for 28 years.
"Why wouldn't you come," the 64-year-old said.
"Let's face it, there's lots of blokes that aren't; never had the opportunity to be here today.
"It's all about them."
