Volunteers marched to Memorial Oval on Tuesday morning to celebrate National Volunteer Week.
This was the fourth consecutive march and it is held in conjunction with the walk held in Adelaide.
Kylie Crouch, chair of the Community Volunteers Working Group, said this year the group asked community organisations to record their volunteers for the month of April.
She said while they didn't get the amount of responses they would've liked, the result still blew them away.
"Volunteering plays a valuable role in sustaining healthy, resilient communities and contributes significantly to the quality and vibrancy of our society," she told the gathering.
Mrs Crouch said there were 31 different types of sport played just in Port Pirie and there are 51 committees that run those sports.
She also explained that the city was home to 23 service organisations, eight community organisations and 14 educational options.
Between some community organisations and sporting groups volunteer hours were almost 6000, and that was just from the few that submitted their time.
"If we had to rely on paying everyone to undertake these activities it would leave an enormous gap and society would be poorer for it," Mrs Crouch said.
"Who would fight our bushfires, who would coach the under 9s, care for our parks, run our op shops and deliver meals to the elderly. Who would tutor our children, help out with breakfast clubs, help the disadvantaged with mental illness and remove debris from roads when there's strong winds."
"Who would bring our Christmas pageants, Masters Games and not to mention the AFL game that was played at our magnificent oval."
Cr Joby Connor and Member for Frome Geoff Brock, who attended the morning's festivities, praised the work of volunteers in the community.
