The Thevy Festival and Market Day will hopefully become an annual community event after the weekend's "excellent turn out" and the positive feedback organisers have received.
Ceduna mayor Perry Will said the festival and market day, hosted in conjunction with the Thevenard Botanical Park and half court mosaic wall opening, saw several hundred people attend and hopes the event can happen again.
"From all comments that I'm hearing, it might be an annual event," Mr Will said.
"It really hasn't cost us much money and we had a hell of a lot of people turn up, I saw many people walking away with armfuls of goodies."
Peter Treloar replaced Attorney-General Vickie Chapman at the opening of the Botanical Park and mosaic, who also believes the festival and markets will become a regular event.
"It's a really good space now, right in the middle of Thevenard, and I'm thinking it will be very utilised now that it's open," Mr Treloar said.
"The council are certainly talking about making it a regular event."
Mr Will said the event was held for locals.
"We didn't have Oysterfest this year and there seems to be a lot of things that haven't happened, so we wanted to have an event for the community," he said.
There were almost 30 stalls at the event, as well as car and bike displays, with a bouncing castle and educational entertainment for children.
The mosaic wall was designed by Michael Tye with input from the Ceduna Aboriginal Arts and Culture Centre and other local volunteers, and tells a story about the Indigenous fish traps among a local seascape and other sea life.
The federal government's Regional Art Fund contributed to the mosaic through Country Arts SA.
Between 700 and 900 new native trees have been planted in the Botanical Park, as well as an orchard.
Mr Will and Mr Treloar thanked the organisers and contributors for the event, the Ceduna District Council, the Ceduna Aboriginal Corporation, the Thevenard Rate Payers and Residents Association and Buzzy's Enterprises.
