Manager of Opposition Business in the House (Australia)

The Manager of Opposition Business in the House, sometimes called Opposition Leader of the House, is the member of the Australian Official Opposition Shadow Ministry responsible for negotiating with the Leader of the House regarding proceedings in the Australian House of Representatives. Among other things, the topics of negotiation are the order in which Government bills and other items of business are taken, the time allotted for debate, and the timing of Opposition business.

The Manager of Opposition Business in the House and the Deputy Manager are appointed by the Opposition leader. The duties of the Deputy Manager of Opposition Business are largely contingent, coming into play only when the Manager of Opposition Business is absent from the House or is on leave, when he or she is referred to as Acting Manager of Opposition Business.
