Lake Eyre Basin Rivers xvi Garry Hall and his wife, Leanne, run a cattle property in the Macquarie Marshes which depends on the Macquarie River, part of the Murray–Darling Basin. His family has owned their property, The Mole, for four generations, relying on the floods in the Macquarie Marshes to produce beef cattle for the feedlot industry. Garry has lived in the Marshes all his life and carries the striking childhood memory of a Marshes much wetter than today. Dry periods have become more and more frequent. The causes are clear, requiring Garry to become increasingly engaged in how the river is managed. He is the current Chair of the Macquarie Marshes Environmental Landholders Association and is also a member of the Environmental Flows Reference Group, which advises the New South Wales and Australian governments about management of environmental flows to the Macquarie Marshes.

His primary area of research interest is the rivers and springs of central and inland Australia, and most particularly western Queensland and western New South Wales. Adam is the author of many peer-reviewed scientific papers and conference papers. In 2011 his natural history book, Desert Fishing Lessons: Adventures in Australia’s Rivers, was published by University of Western Australia Publishing and in 2012 the book received a certificate of commendation at the Whitley Awards as an outstanding publication on Australian fauna. Adam is an Adjunct Research Fellow at Griffith University (Queensland) and Charles Sturt University (New South Wales). Bob Morrish lived in the natural landscapes of the Lake Eyre Basin in Western Queensland for 38 years, mostly on a small pastoral holding on Kyabra Creek south-east of Windorah, part of the Cooper Creek Channel Country. Bob has long been entranced by the natural beauty of the Channel Country, the deserts and the wetlands through to Lake Eyre. For 19 years, he has been Chair of the Cooper’s Creek Protection Group, a local group who remain committed to preserving the landscapes, ecosystems and biodiversity of the unique Lake Eyre Basin. Bob has qualifications from the University of Queensland in psychophysiological research, but left the academic life to live in the outback landscapes that are dear to his heart.
