Political career
Dr Cornwall served for more than six years in the State Cabinet, first as Minister for Environment and Lands in 1979, and then as Minister of Health and Community Services in two John Bannon governments, from 1982 to the end of 1988.
In the 1980s state health Ministers faced a number of challenges, among them Commonwealth-State financial arrangements under a new Medicare agreement, the structure of the State's health care delivery system, and questions about social justice and equity in public health. Dr Cornwall tightened central government control on hospital administration to improve public accountability and allow hospital services to be shared across the system to better meet patient needs and reduce waiting times.
Dr Cornwall fostered a new approach to health care in Australia that was inspired by the Health For All agenda of the World Health Organization in the 1970s. It championed people increasing control over and improving their health, and viewed health status as inextricably linked to social well-being and economic conditions.
Dr Cornwall championed the development of health and community services for disadvantaged groups, such as women's health services, Aboriginal health services, child and adolescent mental health services, and child protection services. He developed a community-based system of health care that linked health care services to specific population or geographic areas, with funding granted on the basis of the needs of those areas. As part of these reforms a proportion of health care funds were reallocated from hospitals into areas of social disadvantage, resulting in better access to health services for people in social need.
Between 1983 and 1987, Dr Cornwall led the effort to clear environmental lead pollutants in Port Pirie, a town in South Australia whose economy is based on a major lead smelter. The project is widely regarded as one of the most significant public health projects among developed countries.
Dr Cornwall ran an anti-smoking program and introduced Australia's first comprehensive legislative package to restrict tobacco advertising in cinemas, prohibit tobacco sponsorship of sporting events, and establish an independent trust to provide replacement funding for sponsorship of sport and cultural activities (Foundation South Australia). The legislation was significant in paving the way for reforms in other states and the Commonwealth. It set a standard that eventually most of the world followed.
Dr Cornwall introduced legislation decriminalising possession of small quantities of cannabis. He introduced the legislation as a private members bill, having secured support for the policy at the Labor Party convention. He was motivated by a strong belief that decriminalisation would break the nexus between soft and hard drugs, which cause much greater harm to individuals and society.
Cornwall's ministerial career came to an end on 4 August 1988 following a highly controversial defamation case in which he was sued by an orthopaedic surgeon over comments made at the height of public debate over the introduction of Medicare in 1984. Cornwall was advised by Cabinet to resign from his ministerial post, which he subsequently did. In his most recent political memoir 'After Work, After Play, After All', John Cornwall writes of the political and personal pressures at play behind the scenes at the time. Cornwall then resigned from parliament on 31 January 1989.
