OzGREEN programs connect youth with communities to become leaders of innovative sustainable social change

About Us


We believe that when informed and connected, people have the skill and ingenuity to solve the biggest challenges the world faces for a safe and equitable future.



OzGREEN engages, equips and enables people to become leaders of positive social change. OzGREEN educates people around the world, enabling them to take action to improve their environment.

OzGREEN is an independent not-for-profit that was founded in 1992. Our unique approach incorporates citizen science, transformative sustainability education, participatory leadership and community development; all centred on enabling community driven sustainability solutions. OzGREEN is one of the leading citizen science organisations in Australia and has a long history of working in the Murray-Darling region, India and East Timor. 

Under the leadership of Sue Lennox, Co-Founder and former CEO, OzGREEN has worked with over 1,600 communities globally and trained 50,000 environmental leaders. Over past 2 years since Co-Founder Col Lennox died, the organisation has had major setbacks. In 2019, OzGREEN is delighted to introduce Anton Juodvalkis as CEO. Anton has been a member of the OzGREEN Board for over 2 years. Read More


 It is now more than ever we need OzGREEN in the world. There is a very small window of opportunity to tackle big challenges like climate change and the Murray-Darling. Youth have a key role to play. It is great to have Anton bring new energy and commitment to help OzGREEN achieve even greater impact. There are enormous opportunities at this time.

Our Vision

A society that is actively engaged in building ecologically sustainable, socially just and equitable ways of living. 


Our Mission

Our Mission is to build sustainable, resilient communities by enabling people to tackle the ecological and social challenges of our times and accelerate the transition to sustainability. 


Our Programs


OzGREEN offers award winning, transformative learning and leadership programs that inspire people to tackle sustainability challenges and become leaders of positive social change. 


Youth Leading the World

Our flagship program, Youth Leading the World (YLTW) prepares young people to succeed in tackling the massive environmental challenges the world is facing. YLTW equips youth to strengthen their wellbeing, create resilient communities and nurture the environment, allowing them to drive positive social and environmental change in their communities.


Our MYRiveR program enables young people to become citizen scientists, test the health of the environment, identify key environmental threats and values, develop their own vision and implement their own action plans to sustain the health of their local waterways.

YOUth LEAD Development Program


"OzGREEN’s Youth Leading the World educational and leadership program is revolutionary in that it engages youth and applies the concept of exponential growth to solve the urgent environmental problems that confront us.  No-one else is doing this."
