Climate Defenders Australia (CDA) is the first dedicated legal service to protect, empower and advance the rights of frontline climate and environmental defenders in Australia. With roots in civil society, justice initiatives and the environmental movement, our team combines legal expertise with their own lived experience of climate advocacy.
What started over a decade ago as a plan to fill a critical gap in the climate justice movement has since developed into a bold and independent leader of its own - providing specialist legal education, advice and representation to climate defenders when they need it the most.
With Australia’s increasingly harsh anti-protest laws combined with the highest arrest rates for climate protestors in the world, CDA is meeting the escalating needs of defenders on the coalface of the climate crisis.
Working with the movement, backed by our supporters, together we are a force for nature.
Now more than ever, it is crucial that an independent legal service be created to advocate on behalf of climate and environmental defenders and meet the unmet needs of those calling for urgent action to save the planet.

Our history
Climate Defenders Australia is a new organisation with a long history.
We evolved from a small, state-based Program established by the Environmental Defenders Office NSW (EDO) over 15 years ago to uphold the democratic rights of environmental defenders.
In 2020, the Program expanded into a nationwide legal service, providing specialist legal representation to climate defenders facing harsh anti-protest laws and unprecedented penalties throughout Australia.
In 2022, we initiated a constitutional challenge on behalf of the Knitting Nannas, to newly introduced anti-protest laws that had been widely condemned by over 230 civil society groups. The case successfully argued parts of the laws impermissibly burdened the implied freedom of political communication.
There was no other program of its kind within the Australian environmental movement, and our work was recognised both domestically and internationally as an innovative model of best practice.
In 2024, in recognition of the increasing needs of environmental and climate defenders, the EDO and Greenpeace Australia Pacific worked together to support the establishment of a new, wholly independent, legal organisation.
On 1 May 2025, Climate Defenders Australia was reborn. We opened our doors to legal practice on 1 July 2025.
