So where is Kooragang Wetlands? Who looks after it?

You can see it here on Google Maps.
Access is by crossing the Hunter River using the concrete bridge at Hexham (opposite Shamrock Street and Hexham McDonald’s). Kooragang Wetlands is open to the public and is now part of Hunter Wetlands National Park, which is managed by the National Parks and Wildlife Service. Standard park regulations apply.

The Friends of the Schoolmasters House Inc. occupy the historic cottage once home to the headmaster of the local Ash Island school. Amongst the projects they are working on they are currently digitising a library of books, photos and other important material they have relating to the area’s history to make sure it is protected for the future.

Hunter Local Land Services have a works facility and volunteer program and are involved in supporting revegetation and natural resource management on and beyond Ash Island.
