2017/18 National Committee

On 9/12/17 the following committee was appointed:

William Bourke
President and Secretary


William is the founder of Sustainable Australia (est. 2010).

In 2009, after hearing Kevin Rudd declare his support for "a big Australia" population of 40 million - and being shocked to discover that the Liberal and Greens parties also support very high immigration and rapid population growth - he decided it was time to get involved in politics and start a new mainstream political party.

William has completed a bachelor of business (accounting and finance) and master of business (marketing). He has extensive business experience including as a partner in a marketing small business for over 10 years, and previous experience in accounting and government communications. He has travelled widely including in Asia, North America and Europe, and lived in a number of places in Australia including Sydney, Melbourne, Canberra and North Queensland.

William believes that rapid population growth is causing or exacerbating most of our local, national and global problems. He is equally concerned about economic, environmental and social issues. Particular concerns include the decline of Australian manufacturing and economic diversity, the destruction of our natural and built environments, and the housing affordability crisis locking many out of the great Australian dream.

William enjoys nature, bushwalking, beaches, running and travelling. He grew up on the urban fringe with bushland as his extended backyard and weekend recreation. He wants to ensure that we fulfil our primary moral responsibility to pass on an economically, environmentally and socially sustainable Australia to our children and grandchildren.

Brad Harris
Vice President


Brad is the Co-Founder and Director of the multi venue restaurant chain The Sporting Globe Bar & Grill, his areas of corporate expertise are in Operations, Systems, Structures and HR.

He also sits on the Epworth Medical Foundation Board of Trustees overseeing governance and financial guidance for Victorias largest not for profit healthcare provider.

Brad is passionate about improving the quality of life for all Australians by addressing key causative factors such as rapid population growth. He believes this will be best achieved through the election of Sustainable Australia candidates into State and Federal parliaments. 

Susan Bowes
Committee Member


Susan is based in Hobart and works in the public education and training sector. She firmly believes politicians and media need to accept there is a problem and include population stabilisation at the top of their agenda. She is convinced that Sustainable Australia has the vision, policies and practical solutions to help implement a better future. Susan can often be found bushwalking, is a keen recreational cyclist and volunteers as a wildlife rescuer.

John Haydon


John has held senior positions during his 25 years with the federal Department of Immigration, and as well as the Bureau of Statistics. He holds three university degrees including a Bachelor of Economics, and a Masters of Business Administration from Adelaide University.

As someone trained in economics, John is concerned at the waste that results from unsustainable population growth and property speculation. John suggests if Australians weren’t paying high property prices, savings could be better spent on starting new businesses, generating jobs, including in manufacturing which he believes has been given away by the Big Parties.

John also holds a leadership position in a community education organisation where he is an advocate to government for effective and efficient public schooling in the ACT. When he is not asking for the vote for a Sustainable Australia, John enjoys riding his bike through the countryside, and life with his wife and daughter.
