A development plan for the largest component of the complex, the Queensland Performing Arts Centre (QPAC), built as Stage Two, was released in 1976. The project architect for the Centre was Allan Kirkwood from Robin Gibson and Partners and contributors to the development and design of the Centre were theatre consultants, Tom Brown and Peter Knowland, the Performing Arts Trust and user committees. Completed in November 1984 by contractors Barclay Bros Pty Ltd, a concert for workers and the first public performance were held in December ahead of the official opening by the Duke and Duchess of Kent on 20 April 1985.
