Since its creation in 1987, the Port Arthur Historic Site Management Authority (PAHSMA) has been responsible for preserving and maintaining one of Australia’s most important heritage sites and major tourism destinations.
In 2004 the Authority was also given responsibility for the Coal Mines Historic Site, located near Saltwater River, about a half hour drive from Port Arthur on the Tasman Peninsula.
For this reason, reference is often made to the Port Arthur Historic Sites.
