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, the Port Arthur Historic Site on the Tasman Peninsula, approximately 100km south east of Hobart, Tasmania.

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. During 2011, the Authority was also given management responsibility for Cascades Female Factory Historic Site, in South Hobart.

All three sites under PAHSMA’s management are included on the World Heritage List as three of the eleven sites that constitute the Australian Convict Sites World Heritage Property, inscribed in 2010.

Due to its responsibility for multiple sites, reference is often made to the Port Arthur Historic Sites.

PAHSMA is a Government Business Enterprise and operates under the provisions of the following principle acts of Tasmania’s State Parliament:

PAHSMA is committed to the aims and objectives of the Public Interest Disclosures Act 2002 (the Act). It does not tolerate improper conduct by its employees, officers or members, or the taking of detrimental action against those who come forward to disclose such conduct.

To connect people with a complex history to inspire, engage and shape the future.

To be the leader in conserving, creating and sharing our extraordinary Australian convict places, experiences and stories.

To enrich the lives of our communities by providing cultural, social, environmental and economic benefit.

Members of the Port Arthur Historic Site Management Authority’s Board are appointed by the Tasmanian Government.
