Parliament, Administration and Services is one name given to the agency which assists the activities of the Parliament by maintaining the necessary administrative and other practical services required by Parliament. The agency has also been known as the Department of Parliamentary Services.

Its responsibilities include reporting on parliamentary debates, staffing the Parliamentary Library, managing infrastructure, information technology support, ground maintenance, human resources, finance, training and development, and catering.

Some records held by Parliament which are not able to be clearly attributed to other Parliamentary agencies (eg the Legislative Assembly or Legislative Council) have been attributed to Parliament, Administration and Services as the agency which captured the records.
