The Eurobodalla Shire Council says it is giving the Moruya Apex Park a "facelift", with a focus on creating picnic opportunities and summer shade using pest and disease-resistant plants and trees with low-water needs.
A council spokesperson said there would be a tree-lined avenue, new shade trees and a feature garden.
Work would begin on the week starting September 9.
The spokesperson said a mistletoe-infested pin oak growing next to the amenities block was assessed as a public risk and would be replaced by a shade-giving blueberry ash tree.
The park, adjacent to the Princes Highway, was the only park visible to drivers passing directly through town. It had a bus stop and amenities block.
The amenities block garden would be replanted with low-maintenance natives and would include a feature rock to complement the plaque, recognising the role of granite in the town's development.
The path running diagonally across the park would be planted out with fast-growing brush box to create a tree-lined avenue.
Most of the park - including the toilets, picnic tables and bus stop - would remain open when work began, with some areas restricted and the public reminded to care when passing through the area.
