Management Committee

Darling Downs Environment Council is managed by a committee, which is elected each year at our Annual General Meeting.

The Committee meets monthly at the DDEC's office in Australia Arcade, 461 Ruthven St, Toowoomba.

Current Committee members are listed below. For more information please contact us.

Leon Surawski


Leon Surawski is a Civil Engineer with an understanding of the complexity of human society’s dependence on the natural world for its existence and resilience. He has a long association with environmental issues from being involved with Griffith University’s instream fauna survey of Barker and Barambah Creeks, Mt Isa Landcare Group, mine rehabilitation in Western Australia and Nauru, road project environmental approvals and studying for a Masters in Sustainability Studies.

Leon comes to the presidency of DDEC with an understanding that life on earth is now dependent on the actions of humans who have created a new geological epoch called the Anthropocene. He is an advocate of resilience thinking for a better understanding of how to survive in a rapidly changing planetary ecosystem: “Anyone who believes exponential growth can go on forever in a finite world is either a madman or an economist” (Quote from speech by Kenneth Boulding to the U.S. Senate in 1973. Boulding was an economist, educator, political activist and interdisciplinary philosopher).

Lee Mason


Lee Mason is the father of DDEC. After the collapse of The Toowoomba Regional Environment Council (TREC) in 2013, Lee conferred with community groups and individuals to reformulate a strategy to protect, preserve and enhance our precious environment. 

The result was the Darling Downs Environment Council, which was incorporated in October 2014.

Lee is Secretary of DDEC and takes a leading role in liaising with Government and promoting effective environmental regulation. In his day job as a High School teacher he
has taught generations of Toowoomba students the curriculum, but also the highest humanitarian and social values. Lee’s partner Christine nurses at Toowoomba General Hospital.

David Tutty


David Tutty is New Zealand born with a background in science and theology. He worked for many years as the Catholic Social Justice advocate in Auckland before moving to Pretoria to pursue a doctorate in theology. In his research he focused on social change and conversion to justice.

Environmental issues, and particularly climate change, are a key focus of the Commission.
