Dilan Fernando


Originally from Australia, Dilan is a versatile organiser with 6 years’ experience in various movements across the UK, Australia and the USA. After a period of deep reflection in 2019, Dilan left his corporate career to devote himself to animal justice work. He is now focused on Animal Think Tank’s Culture and Governance workstreams. Drawing from ideas like Teal management, Sociocracy and Swarm organising, Dilan seeks to understand how we might build resilient, agile, and truly democratic social movements that unite people from all walks of life.        

Previously, Dilan coordinated the Media team at Animal Rebellion. Working with various campaigners, Dilan helped the idea of a plant-based food system reach deep into the mainstream, with Animal Rebellion garnering 350+ press appearances across national TV, radio, online and print media. Dilan was also instrumental in planning initiatives like Animal Rebellion’s landmark nonviolent occupation of Smithfield Meat Market

Dilan’s animal justice journey began in 2015, after an experience that saw him befriend an injured puppy in rural Cambodia. He soon discovered the idea of speciesism, promptly took up veganism, and while studying in North America he was introduced to nonviolent direct action. Dilan then joined the vibrant animal justice community in Melbourne, Australia, where founded the Monash University Vegan Society, co-organised the 2017 March to Close All Slaughterhouses, and presented at conferences held by Animal Activists Forum and the Institute for Critical Animal Studies

In 2017 Dilan co-founded the non-profit group Young Voices for Animals with fellow ATT member Harley McDonald-Eckersall. With YVA, he pioneered Catalyst, a youth leadership program, and co-organised Australia’s first Youth Animal Rights Conference. 

Years earlier, Dilan’s social change journey started in the anti-poverty movement when he was asked to be a volunteer leader on Oaktree’s Roadtrip to End Poverty, and later took on a key coordinator role at Monash SEED. He has also campaigned with the environmental movement, having coordinated election calling parties with the Australian Conservation Foundation.  

Dilan holds double Bachelor’s degrees in Commerce and Economics from Monash University, Australia. His business experience includes a Marketing role at National Australia Bank, an internship at Pitcher Partners, and a stint volunteering in the Fijian microfinance industry with Good Return

Outside of work, Dilan loves hot chocolates, reading, exploring new places and immersing himself in video game worlds. He is an avid cinema-goer and cricket fanatic.

Esther Salomon


Esther delved into animal justice work early in her life and holds a love for natural intuition and wisdom that’s gained from real world experiences. Feeling disillusioned with chasing academic success, Esther turned down an offer to study Politics at Edinburgh University. During this time she realised that building people-powered organisations into a political force was needed to bring about the sweeping changes that she had wanted to help shape through the degree. 

She turned vegan early in College after spending three months as a vegetarian, it was during these years when her understanding of animal oppression and speciesism began to grow into a desire for meaningful action. Esther spent the first portion of her life surrounded by politically minded people from diverse backgrounds which led her to explore issues of justice from different perspectives.

From the need to connect to the natural world Esther trekked across the Annapurna mountains and came away with a deep respect and awe for the planet and all its animals. While there, she developed a curiosity around parts of Eastern philosophy that touched on the value of all forms of life. Her interest in the significance of human-animal relationships in our culture and history was sparked here. But after visiting several major cities around the world the reality of economic inequality and social injustice became clearer than ever. The experiences, conversations and people that she came across acts as an anchor in her day to day work. 

Esther became a full-time member of Animal Rebellion, moved to London and helped kick-start the organisation in June 2019. In her time there Esther learned the value of building bridges between movements through shared values and experience as well as building foundational skills in facilitating training, leading workshops and speaking at conferences and events. Reaching back to her time visiting her family in Kerala, she witnessed the potential of truly empowered communities who are able to act on their local concerns and work to find solutions together. This enabled her to grasp how to inspire, mobilize and coordinate volunteers to take action. She played a part in designing the tone and events of Animal Rebellion’s occupation of Smithfields market in October 2019. A few months earlier she had led a call to action and declared the demand for a plant-based food system to thousands of people at the Official Animal Rights March in London. 

Now in Animal Think Tank, and drawing from social movement theory, Esther is keen to explore how to create strategies that have the power to work within our current society, engage and inspire the public and make lasting change possible.
