The National Capital Authority (NCA) is established under the Australian Capital Territory (Planning and Land Management) Act 1988 (the Act).

The Act establishes the NCA, prescribes its powers and functions and makes it subject to general ministerial direction. The Minister for Home Affairs, the Hon. Brendan O'Connor MP administers the Act.

The statutory functions of the NCA comprehensively establish the Australian Government's continuing interest in the strategic planning, promotion, development and enhancement of Canberra as the National Capital.

The functions of the NCA provide an enduring framework to secure the planning and development of Canberra as the capital; to accommodate the Seat of Government and associated national and cultural requirements; to provide national public places for all Australians to visit and enjoy; to enhance the unique character and symbolic meaning of the capital; and to develop appreciation of the capital as a reflection of our democracy and national life.

The Authority consists of a Chairman, a Chief Executive and three other members, all of whom are appointed by the Governor-General. The Chief Executive is full-time while the other four members serve on a part-time basis. The Chief Executive manages the affairs of the NCA under the general directions of the Authority and has the responsibility of a Secretary under the Financial Management and Accountability Act 1997 and as an Agency Head under the Public Service Act 1999.

The current members of the Authority are:

• Chairman, Don Aitkin AO;
• Chief Executive, Mr Gary Rake;
• Mr Peter Core;
• Ms Shelley Penn, and
• Ms Christine Storry
