Flinders Island Marketing & Development Group chairwoman Liz Frankham said the event, which happened between Thursday and Sunday last week, was "extraordinary".

"We had a few days of community events and then our major event - the long lunch - on Saturday," Ms Frankham said.

"People were flying in from Sydney, Western Australia, South Australia and all ports in between.

"Everyone wants to buy a property here now," she laughed.

Flinders Island Marketing & Development Group established the festival as a "destination awareness program" and it has been very successful in that respect, but has also brought the community together too.

Residents were involved in the sausage sizzle at the showground on Thursday night to welcome visitors and voted on their favourite sausage flavour combination.

"We had lamb and mutton bird, flathead and octopus, vegetarian and beef sausages. I voted for the lamb and mutton bird - it was absolutely sensational," Ms Frankham said

"We had about 200 to 300 people there. It was 60 per cent from off island and 40 per cent locals, and they were fantastic with their hospitality."

Community members also held an art walk on Friday night, where 12 pop-up art venues hosted displays of island artists' work and school pupils told the Moon Bird Story through a film they helped to produce.

A community market finished the festival on Sunday, supported by visitors and residents alike.

"All the accommodation places were full and car hires taken. We had a full island over the weekend," Ms Frankham said.

"The airport was the busiest place yesterday [Sunday]. Hopefully we'll have great ambassadors for Flinders Island now."
