For former chairman Doug Prosser and executive officer Brian Dooley, giving the public access to 85 per cent of Lake Illawarra's foreshore ranks among the highlights.

The production of a new booklet documenting the shareways around Lake Illawarra will be one of the final acts of the Lake Illawarra Authority.

The LIA board was disbanded by the NSW government in July. However, the authority still exists under the umbrella of the Department of Trade and Investment until the NSW government repeals the LIA legislation.

Mr Dooley said the 32-page booklet includes a series of maps to guide the community on ways to get to the foreshore of the lake and how the community can get around the perimeter of the lake using shareways or walking paths.

"You can get around 85 per cent close to the lake edge, but you get around the entirety of the lake by using adjoining roads," Mr Dooley said.

"The booklet also shows all the park assets, lookout areas, picnic areas, toilets and fishing platforms - it is a great document."

Two pages in the booklet are reserved to identify birds and plants people may encounter as they make their way around the lake.

The booklet and a smaller pamphlet are available free of charge at tourist centres in the Illawarra.
