Streaky Bay's Josephine Williams will be one of the long-serving Meals on Wheels volunteers acknowledged at its upcoming Awardee Day lunch.
The event will recognise volunteers who have reached key milestones in their service.
Ms Williams is being acknowledged for 40 years with Meals on Wheels at Streaky Bay, although she is unable to attend the Adelaide event.
The day, to be led by South Australian Governor Hieu Van Le, will celebrate the achievements of Ms Williams and 30 other volunteers or branches ranging from 40 years of service to 65.
Mr Van Le and his wife will present the 40-plus years awards.
Ms Williams said she was happy to receive the award, but did not volunteer for the recognition.
"I've never really thought about it (the length of service) as it's a good organisation, it is good for the town and I am happy to be involved with it," she said.
"I do it for the fact the elderly have someone calling in every day, and it's such a good service - you meet lovely people and it's a good thing to do.
"It's good for us as carers as well as the older people, it benefits both."
Ms Williams is one of a number of Streaky Bay volunteers who operate on a six-week roster.
She said she started with the Streaky Bay branch the year after it opened and that a lot had changed in 40 years of delivering meals.
"It was always locally run back then, we had our own budget and own car and everything was done locally, and I thought it was sad when it went big-time to the city," she said.
"It was good to have it locally run.
"I've always been on a Friday and we used to collect money and write receipts, now everything is done online."
Ms Williams said her intention was to keep delivering meals for the organisation.
Meals on Wheels chief executive officer Sharyn Broer said the annual event was a chance to publicly thank and congratulate the volunteers.
She said volunteers selflessly provided a vital community health service.
"As well as preparing and delivering nutritious meals, our volunteers carry out highly valued welfare checks and social interactions with people in need right across the state," she said.
"They are incredible people who tirelessly and quietly go about their work.
"It's fitting they receive this much deserved recognition and our sincere thanks on behalf of the entire community."
