Martin has been working to safeguard the natural environment for over 20 years, protecting endangered species, rivers, threatened ecosystems and Ramsar-listed wetlands in South West WA and the Kimberley. In partnership with Traditional Owners and other conservation organisations he has led EK’s efforts to have 30,000 km² of the Kimberley coast secured in marine parks, to stop a coal mine from being built on the Martuwarra Fitzroy River and a copper mine at the Horizontal Falls, as well as to prevent James Price Point from being destroyed by one of the world’s biggest gas factories which would've led to the wholesale industrialisation of the Kimberley. He advocated, with the leadership of Traditional Owners, for the National Heritage listing of 19 million hectares of the West Kimberley and new National Parks along the Martuwarra, as well as against its surface water from being taken for irrigation. Martin was the Executive Director of EK from 2008 to 2023, recently stepping into the role of Director of Strategy.
