Jennifer Marohasy
Director, Environment Unit, IPA

Biographical Details

Dr Jennifer Marohasy joined the IPA on 1 July 2003 as Director of the newly formed Environment Unit. The Unit has been established to provide market-based, science-driven solutions to environmental problems.

Jennifer started life on a cattle station in the Northern Territory before attending boarding school in Brisbane. After completing a science degree at the University of Queensland she worked for seven years in remote parts of Africa in search of biological control agents for some of Queensland worst rangeland weed species. She was awarded the Australian Cattlemen's Union Research Medal in 2001 in recognition of her contribution towards the biological control of rubbervine (Cryptostegia grandiflora).

During the 1990s, Jennifer published 12 papers in international and Australian scientific journals and 2 book chapters. Her PhD research challenged the theoretical basis for the protocols then used to test host specificity in potential biological control agents and is recognised as contributing to a paradigm shift in biological control research. In 1998, she was invited by the United States Department of Agriculture to give the keynote address at the annual general meeting of biological control scientists in Hawaii.

In 1997, Jennifer started with the Queensland Canegrowers Organisation as Environment Manager overseeing the development of an industry-wide best management programme, endorsement of the first commodity-specific code of practice under the Environment Protection Act 1994 (Queensland), development of submissions to government enquiries and also assisted regionally-based officers develop plans and strategies particularly in the areas of environmental management and pest management.

Over the last 2 years, Jennifer has developed an interest in anomalies between fact and perception regarding the health of the Great Barrier Reef. She co-authored a critique of WWF's reef campaign (WWF Says 'Jump!' Governments Ask 'How High'? [65k PDF file]) and has more recently challenged perceptions regarding water quality in the River Murray (Received Evidence for Deteriorating Water Quality in the Murray River).

As Director of the Institute's recently formed Environment Unit, Jennifer hopes to work with a network of committed individuals to inject some real science and economics into public policy decision-making on environmental issues.
