The following year, the Treasury Department initiated a formal investigation into a suitable site for an art gallery, led by Treasurer, Deputy Premier and Liberal Party Leader, Gordon Chalk. An expert committee, including Coordinator-General Charles Barton as chair, Under-Secretary of Works David Mercer and Assistant Under-Secretary Roman Pavlyshyn, considered 12 sites, including those from previous proposals. Three sites were shortlisted: The Holy Name Cathedral site in Fortitude Valley; upstream of the Victoria Bridge at South Brisbane; and the BCC Transport Depot in Coronation Drive. The South Brisbane site was preferred, considered to be the most advantageous for the city and the most architecturally suitable. The recommendation was accepted and work on progressing a design commenced.
