The Gallery has four major functional divisions:

• Curatorial Services
• Finance and Management Services
• Exhibitions and Building Services
• Marketing and Business Development

Each of these divisions is managed by a general manager, who is a member of the Gallery's senior management team. Within these divisions, activities are divided into departments which are the responsibility of the relevant department head. The general managers all report to the Director of the Gallery. Also reporting to the Director are the staff employed within the Directorate and the Benefaction Services Manager.
