The Mosman Parks and Bushland Association Inc, originally The Ashton Park Association, was formed in 1964 by a group of residents who objected to the bulldozing of bushland in Ashton Park, now part of Sydney Harbour National Park.

The Association has since played a major role in preserving Mosman’s individual character and landscape. The fight for bushland was also fought literally ‘at the grassroots’: members actively supported Eileen and Joan Bradley in developing bush regeneration here in the 1960s-70s. The Association published Joan Bradley’s seminal Bush Regeneration in 1971. Members continue to work in this area as volunteers.

In the 1960s the Association with other groups such as the National Parks Association developed the concept of bushland management, a novel idea then, and lobbied with the NPA for a system of national parks in NSW.

Former Mayor of Mosman, the late Barry O’Keefe, told some wonderful stories about working with the Bradley Sisters in a video clip he recorded for Mosman Library.
