There is an excellent guide written by the Mosman Historical Society in 2010, about the Bradleys Head area, which encompasses Sirius Cove, Athol Bay, Bradleys Head itself and around the point to Taylors Bay.
The Bradley Sisters developed their famous techniques for bushland regeneration while fighting the many invading species of imported exotic flora that were dominating the native flora in that area.
The community group formed in 1964 that became closely identified with their work was originally called Ashton Park Association, after the regeneration work done in Ashton Park on Bradleys Head.
The Ashton Society morphed into the Mosman Parks & Bushland Association in 1982. (check date with Kate Eccles)
