Sparked by the draft Wagona estuary management plan's suggestion that the bridge to the island be demolished, the residents will now form an incorporated "Friends of Lewis Island" group.

Likely to be involved are Lindsay Quonoey, Chris Young and Bob Bennett who met with councillor Lindsay Brown on the island on Monday morning.

Mr Brown said council would listen to the community and suggested a meeting with Eurobodalla Shire Council's roads and recreation manager Warren Sharpe in the next few weeks.

The draft estuary plan for Wagonga won't be finalised by the council for some months.

But more pressing than just preserving the bridge access was the future of the sandy island. Every year Lewis Island is becoming smaller with floods, shifting sands and perhaps most worryingly destruction from boat wash with the main channel directly off the islands banks.

"The bridge is okay for another six or eight months but unless we do something here, we won't have an island," said Mr Quonoey purveying a sense of urgency while pointing to the sandy bank that had retreated several metres from the remnants of the rock wall built by a local work for the dole program back in the '80s.

The group acknowledged that any shoring up of the island would have to be done in consultation with State Government agencies such as Fisheries, Environment and Maritime.

Riverview Drive resident Chris Young agreed to contact Maritime NSW to request an extension of the waterway speed limit along the channel from the bridge to past the island.

There was also mention of getting groups such as Greencorps involved while the NSW Recreational Fishing Trust could pay for a new jetty out onto the water to assist kids' fishing.

Council planners had recommended the demolition of the bridge as a cost saving measure, while the island would be set aside as a nature sanctuary.
