More than 1000 people gathered by the Port Lincoln War Memorial for this year's Anzac Day dawn service to mark the anniversary of the Gallipoli campaign of World War I and commemorate those who have served in the defence force.
Royal Australian Air Force squadron leader Lauren Flaherty flew from interstate to stand beside her father, Port Lincoln mayor Brad Flaherty and to give the Anzac address.
She said the roll of honour at the Australian War Memorial held the names of more than 102,000 Australians that had died in operations across the globe, with more than 23,000 having no known graves.
"We are the beneficiaries of the actions of our first Anzac's and those who have fought for Australia since," she said.
"We demonstrate our gratitude by remembering their sacrifice and by honouring the values they first fought for over 100 years ago and continue to fight for today.
"This is the payment we make against a debt we can never full repay."
Squadron leader Flaherty said April 25 gave us the opportunity to consider the broader purpose of Anzac Day.
"Today...we can not appreciate firsthand the relief and grief our ancestors felt, but we can still take pride in the contribution our defence force continues to make on the world stage," she said.
