There has been much debate in the literature about the impact of globalisation on the Australian economy, but few studies focus on the domestic determinants of Australia’s negotiating position in international trade negotiations. In order to close this gap, this article analyses the impact of organised interest groups in the Australian trade policy under the Howard government in the different World Trade Organization (WTO) ministerial meetings from 1999 to 2006. In particular, the article explores the link between parties and interest groups in the Australian political system. It suggests that the Australian negotiating position reflects the demands put forward by interest groups closely linked to the government parties and the change of the international environment towards bilateral and regional trade agreements.
