Leach worked for many years in the Australian Tax Office after completion of a degree in Economics.
Leach's work has been exhibited in several museum shows including "Optimism" at the Queensland Art Gallery[2] and "Neo Goth" at the University of Queensland Art Museum[3] in 2008, in 2009 "the Shilo Project" at the Ian Potter Museum of Art [4] and "Horror Come Darkness" at the Macquarie University Art Gallery [5] and "Still" at Hawkesbury Regional Gallery in 2010.
[6] His work is held in public collections of regional galleries of Geelong, Gold Coast, Coffs Harbour, Newcastle and Gippsland and the collections of La Trobe University and the University of Queensland.
The award has generated some controversy [9] due to the similarities, acknowledged by Leach, between his work [10] and one by seventeenth-century Dutch artist Adam Pynacker.
Leach's work has been featured in numerous group exhibitions.
