This report contains the five Invited Plenary Session papers presented to the Second National Social Policy Conference held at the University of New South Wales on 3-5 July 1991. The theme of the Conference, Social Policy in Australia: Options for the 1990s forms the title of the report. The Social Policy Research Centre is also publishing two volumes of selected contributed papers in the SPRC Reports and Proceedings series as well as editing a Special Issue of The Australian Quarterly (No. 3, 1991) containing a further selection of contributed papers. The five papers included in this report address issues at the heart of the contemporary social policy debate, including the relationships between the Welfare State and the labour market, between economic and social policy, between broader international forces and national developments, and between the balance of forces impinging on the future of social policy.
