This thesis is the first systematic history of the Geelong Regional Commission (GRC), and only the second history of a regional development organisation formed as a result of the growth centres policy of the Commonwealth Labor Government in the first half of the 1970s. In particular, the thesis examines the historical performance of the GRC from the time of its establishment in August 1977 to its abolition in May 1993. The GRC Commissioners were subject to ongoing criticism by some elements of the region's political, business, rural and local government sectors. This criticism focused on the Commissioners' policies on land-use planning, their interventionist stance on industrial land development, major projects and industry protection and their activities in revitalising the Geelong central business district. This thesis examines these criticisms in the light of the Commission's overall performance. This thesis found that, as a statutory authority of the Victorian Government, the GRC was successful over its lifetime, when measured against the requirements of the Geelong Regional Commission Act, the Commission's corporate planning objectives and performance indicators, the corporate performance standards of private enterprise in the late 1990s, and the performance indicator standards of today's regional economic development organisations in the United States of America, parts of the United Kingdom and Australia. With the change of Government in Victoria in October 1992 came a new approach to regional development. The new Government enacted legislation to amalgamate six of the nine local government councils of the Geelong region and returned regional planning responsibilities to the newly formed City of Greater Geelong Council. The new Government also made economic development a major objective of local government. As a result, the raison d'etre for the GRC came to an end and the organisation was abolished.
