National Media Spokesperson

The Hon. Kelvin Thomson

The Hon. Kelvin Thomson served as an Australian Labor Party Councillor for the City of Coburg from 1981 to 1988, Member of the Victorian Parliament for Pascoe Vale from 1988 to 1996, and Federal Labor Member for Wills for over 20 years from 1996 until the 2016 Election.

Kelvin has extensive knowledge of all three levels of government. His campaign experience - he stood for public office 12 times in his career and was successful on each occasion - and his policy development expertise, having been a Shadow Minister for the Environment and Shadow Attorney General amongst other Shadow Ministries and parliamentary roles, make him an accomplished media spokesperson.

Kelvin is currently the Chief of Staff to Sustainable Australia Party's Victorian Upper House MP Clifford Hayes.

Kelvin Thomson played a key role in kick-starting the population debate in Australia 10 years ago, with a speech he gave in Parliament in August 2009, and with a media release he put out in September 2009, in response to Treasury figures showing that Australia's population would be 35 million by 2049, a massive jump from the previous projection of 28 million by 2049, made just a couple of years earlier. He described this as a recipe for environmental disaster and called for population reform.

2018/19 National Committee

On 15/12/18 the following committee was appointed:

William Bourke
President and Treasurer

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.

John Haydon
Vice President


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 has held leadership positions in community education organisations at the ACT and national levels where he advocated to government for effective and efficient public schooling in the ACT and nationally. When he is not asking for the vote for Sustainable Australia, John enjoys riding his bike through the countryside, and life with his wife and their daughter who attends the local high school.

Mark Ferris

Mark has a broad background in media production. He initially worked in the film industry on a variety of productions from short films through to Hollywood backed feature films. Since then, Mark started his own business providing media content services for a variety of businesses and organisations. He also has a Bachelor of Arts - Psychology. In his spare time Mark enjoys volunteering with several community organisations as well as running, camping and travelling.
