In the dark chill of an Anzac Day dawn service, young men stand in neat suits, solemn and reflective with rosemary pinned to their chests.
Attending their local RSL service is a tradition for the group of friends, an event repeated since they were 18.
But new traditions have also taken hold in recent years.
After the ceremony the gen Yers get out their phones to check social media and `share'.
While thousands of Australians continue to get up in the dark to gather at war memorials, others will just turn to social media to mark the occasion.
On Snapchat, they'll swipe through the app's customised Anzac Day filters - a frame of red poppies, an italicised Lest We Forget caption, the outline of a digger against a hill - to decorate the photo they send out into the online ether.
Scroll through Instagram and it's a stream of poppies and Lest We Forget illustrations.
On Facebook, users share more personal tributes such as photos of grandkids next to digger grandparents at a parade or recollections of war tales told by vet relatives.
Hashtags such as #grateful, #gratitude, #heroes, #proudtobeaustralian and #thankyou sum up the online mood.
Officials also reach out through their online channels and the #anzacday16 hashtag.
At dawn the navy posted a video of the sun creeping over the horizon on Facebook that's been viewed more than 17,000 times, while Defence shared video messages from troops in the Middle East.
Prime Minister Turnbull posted an Instagram shot of the crowds at his North Bondi service with the caption #lestweforget.
On the 100th anniversary of the first Anzac Day, social media has become the go-to outlet for remembrance.
