St Joseph's School students have sent out more than 100 letters to organisations and services who helped the community during the Duck Ponds bushfire on November 11.
Students wrote letters of thanks to the many people who helped fight the fires, ensure safety or help those who had been affected.
This includes to the CFS, MFS, SAPOL, SES, SA Power Networks, Salvation Army, Vinnies Port Lincoln. Aerotech, Department for Environment and Water and Port Lincoln Hotel among others.
Year 6 teacher Lisa Kuerschner came up with the idea in the week following the Duck Ponds fire and said it was something she wanted to do with her students.
"I mentioned it at a weekly staff meeting and aksed if any other teachers were interested in adding to the pile," she said.
About seven classes across the primary and middle school joined in with more than 100 letters written, with many still yet to be delivered.
Miss Kuerschner said even though the community was always grateful for these services and organisations when an emergency happened, it was important for the children to be able to provide messages of thanks to people who helped keep people safe and secure.
"Making a small gesture of thanks has had a bigger impact than I would've expected," she said.
"After having a fairly traumatic event in the community (the students) were quite excited for the opportunity to thank these people."
Student Abbie Price was one of the students who wrote letters and said "it makes you feel safe to know there's people that will help when needed."
SES Port Lincoln unit manager Max Coulson said the unit's letters were received about a week ago and reiterated why the volunteers did the work they did.
In addressing the students Mr Coulson said having the support of some of the community's youngest members meant a lot.
"Our job is we've got the community's back so it's great to know you've got our back in saying thanks," he said.
