The annual Remembrance Day service was held Monday to commemorate 101 years since the end of World War I and to remember the service of men and women in all wars.
At the service Reverend Dr Robert Dunn read from Psalm 23 and also Romans 5:1-8, before RSL president Peter Linn made the address and spoke of leadership and helping others.
"The Defence Force protects our country and helps others in need...we as individuals can adopt their ethos ourselves," he said.
"I believe we need to develop in our leaders gravitas...I believe this trait in most leaders of today is missing.
"We need to encourage gravitas in our emerging leaders."
RSL vice president and mayor Brad Flaherty also spoke before announcing those laying the wreaths.
"I've never met a successful negative leader," he said.
"We need to aspire to be positive and encourage others to be leaders and aspirational."
Mr Linn said Les Kropinyeri was invited this year to place the first wreath for the RSL, as he would soon be moving away from Port Lincoln.
Following the laying of the wreaths by former servicemen and women, emergency service personnel and schoolchildren, bugle player Doug Monks performed the Last Post before a minute's silence was observed.
The Port Lincoln City Band also played hymns and the national anthem.
