Residents had grown tired of a perceived lack of action to save the section of beach from encroaching rice grass, and were planning to turn it into a community space to add to the nearby Rose Bay Park.

One of the first steps was to clear away excess rocks and debris.

Gravelly Beach resident Russell Hogarth said the beach had potential, and it looked like it was up to the community to carry out the work.

"We need to bring the 'gravelly' back to Gravelly Beach. Why even call it Gravelly Beach if there's none of it left?" he said.

"It's Sunday morning, you could have 100 people on the beach here or picnicking on the grass, more out on the water, with canoes, kayaks, rowing races.

"We just need a clean area to enjoy the river bank.

"We could have the best regatta area in Tasmania."

The area had become unusable due to its boggy state, made worse by impurities in the Tamar River.

Bringing in a layer of sand and pebbles to the small beach was one part of a broader plan developed by the community to enhance the town's foreshore.

The Gravelly Beach Foreshore Committee also had plans to turn another rice grass-infested area alongside the small beach into a park with a playground and more barbecue facilities.

They were against removing the rice grass, believing the removal at another section had eroded the concrete boundary and caused further problems.

Instead they want to add clean-fill to the rice grass and border it with rocks - a similar method the community used to create Rose Bay Park.

Recreating the beach and another public park would help Gravelly Beach's foreshore to be entirely made up of usable parks and beach areas, volunteers at the beach on Sunday said.

Maria Oldman said an improved foreshore would have benefits for residents, businesses and tourism on the Tamar River.

"Rose Bay Park has a lot of patronage and the community worked so hard to make that happen," she said.

"Imagine how many more people would come and use Gravelly Beach if we had parks and beaches right around."
