The boardwalk is over 30 years old and according to a spokesperson from council, "is in desperate need of a makeover".

The project will also include the construction of walking paths from the Jervis Bay Maritime Museum to the Woollamia boat ramp.

A spokesperson from Shoalhaven city council said the boardwalk required a refurbishment because the current narrowness was not conducive to easy pedestrian passing and had become uneven as the timbers had warped.

"It is proposed to refurbish the structure to create a durable boardwalk with a wider pathway, improved accessibility features, educational bays, intermittent seating and interpretative signage," the spokesperson said.

"The upgrade is important to provide greater accessibility to everyone that would like to visit the area."

Secretary of Huskisson Woollamia Community Voice Penny Davidson congratulated Shoalhaven council for securing the funding.

"As long as there is no environmental destruction in it's construction because that would be like robbing Peter to pay Paul.

"And hopefully more footpaths are built in the future to make our streets more accessible."

Shoalhaven council is undertaking the acceptance of the grant and will then enter into a contract with the NSW and federal government. There will need to be a design and approvals stage and signoff. It is expected that construction may start in late 2021 and take the whole of 2022 to complete the project.

Council staff identified that the structure was "growing old" and needed to be brought to today's accessibility standards.

"It performs a great educational asset for schools but was restrictive in how it could be used for school groups," the Shoalhaven spokesperson said.

The grant which secured the funding was submitted by Council's Economic Development Office as a project that supports tourism infrastructure and education. Prepared in late 2020 and lodged in late January 2021, this grant was approved in early July.

"To support tourism as an economic driver in Shoalhaven, the provision of tourism infrastructure is critical," the spokesperson said.

"Built around linkages to nature, be it the fish in the Lady Denman Lagoon, hermit crabs and mangroves in Currambene Creek mudflats or stingrays that float around the boat ramp at Woollamia, it all adds to the Shoalhaven and Jervis Bay experience."
