The Thin Green Line Foundation


Every day, park rangers risk their lives to protect wildlife and habitats from poaching and other threats. Sadly, it’s estimated that over 1,000 park rangers have been killed in the line of duty over the past 10 years, 75% by commercial poachers and armed militia groups. Park rangers are generally under-equipped, underpaid, and often under-appreciated. We think they are heroes and work to provide them with the support they need to continue to protect threatened species around the world.



The Thin Green Line Foundation Protects Nature’s Protectors by providing vital support to park rangers and their communities who are the front-line of conservation. We work predominantly in developing nations and conflict zones, and with Indigenous park rangers within Australia and abroad.

We provide rangers on the front-line of conservation with essential anti-poaching equipment and training, and financial support to the widows and orphans of park rangers killed in the line of duty.

Through our work we aim to ensure that:

  • Park rangers are valued for their vital role at the front line of conservation
  • Park rangers when in contact situations with poachers have the ability to defend themselves
  • Park rangers are provided with decent working conditions and a living wage
  • Park rangers are provided with the skills and tools they need
  • Park rangers families and communities have on-going support when rangers are injured or killed in the line of duty



The Thin Green Line Foundation was founded by award-winning conservationist, documentary filmmaker and Park Ranger, Sean Willmore.

In 2004, Sean set off around the world to make a documentary about the stories of park rangers. Taking almost 12 months to travel through 23 countries, he uncovered  many inspiring stories along the way.

The Thin Green Line documentary premiered in 2007, capturing people’s hearts in over 50 countries. The film has since become an international success story, offering a sense of hope and pride for park rangers around the world.

The documentary became the catalyst for Sean to set up The Thin Green Line Foundation, to support park rangers in danger.



Sean Willmore and the Thin Green Line Foundation have been recognised globally for their conservation efforts, including:

  • Banksia International Award (2014)
  • Pride of Australia medal (2013)
  • Melbourne Award for Contribution to Sustainability (2013)
  • United Nations Association of Australia Environment Award (2009)
