Rising before the sun, a crowd of hundreds turned out to remember those Australians who have served and fallen in armed combat throughout the years.
This year's dawn service in Gladstone Square, like many around the country, marked the 104th anniversary of the landing of Australian and New Zealand troops on Gallipoli.
Port Augusta RSL Treasurer Bruce Henderson said it's important the Australian public play a role in remembering those who served.
"It is a day to remember those men and women who have paid the supreme sacrifice in the Defence of our Nation, those who have been scared physically or mentally, and others who have served and continue to serve in the Australia Defence Force," Mr Henderson said.
"The landing at Gallipoli has traditionally been the focus of the day. However, those campaigns that followed in France and Belgium would prove to be far more costly in terms of casualties and raw courage by the Australian Forces."
Shortly after the dawn service, a traditional gun fire breakfast was held at the Port Augsta RSL Branch.
The Anzac Day March was melding pot of young and old, as a large group walked from Tassie Street, through Commercial Road before turning left on Jervois Street as they congregated at Gladstone Square.
The commemorative service commenced immediately after their arrival around 11am at Gladstone Square, where the Port Augusta Army and Navy Cadets impressed with another perfect performance.
Port Augusta Mayor Brett Benbow was impressed with the large turn out.
"We have had a good attendance, a good mixed crowd," he said.
"We need to recognise the women and men who served our country and gave their lives for what we have today.
"The most important part to me is ensuring our youth remember this moment and attend on these days. I encourage them to support the services that give them the life they have."
After the service the Port Augusta RSL Branch held a wonderful crowd of more than 50 people, supplying supper, lunch and drinks throughout the day.
