IT'S a hugely popular event that attracts thousands of people to Tannum Sands' Millennium Esplanade, but organisers are warning next month's Beach Arts Music could be the region's last.

Organisers say unless more volunteers step up to help, BAM will collapse.

Boyne Tannum Arts Business and Community Association president Jodie Luce has been helping organise BAM since it began three years ago.

"Either we get volunteers or the whole event is over," Ms Luce said. "We simply need manpower."

Ms Luce said Facebook appeals for monthly helpers had been unsuccessful, despite the growing popularity of the event.

"The first few months we ran, we'd get a few hundred people along - when we got to 1000 we thought, 'Wow'," she said.

Now, up to 4000 people gather on the first Saturday of the month.

"These days we have 60 stalls and a waiting list for stallholders," she said. "Our most recent was basically standing-room only."

But running an event of that scale needs many hands, Ms Luce said, and currently the BAM team only has eight volunteers.

"Apart from myself, everyone is over 50," she said. "We need to get people who are a bit younger."

She said the commitment would only be an hour or two every month, and could help newcomers to town make new connections.

"This is an event that people had been crying out for for years. It's somewhere family and friends can get together and enjoy local produce and local talent."

The next BAM is on Saturday, June 1. Willing volunteers should contact Jodie on 0403 087 727 or Maxine on 0448 882 609.
