The Society collects and maintains the history of the former Shire of Cranbourne, with an emphasis on the history of the towns of Cranbourne and Tooradin.

The Society was formed in 1968, its primary aim at the time was to save the "Sportsman Rest" fisherman's cottage,built c. 1873, on the Foreshore at Tooradin, from demolition. This campaign was successful and the building is now a Museum. The Museum Complex also contains the former Tooradin North State School. The Society meets on the fourth Thursday of the month at the Old Shire Offices in Cranbourne.
