Our mission is to REGENERATE culture, community, tradition, heath and our soils. Every product we make includes one or more Native Australian Ingredients.

We must develop a new co-culture approach to the future, drawing on the oldest continuous civilisation in the world and building to the resistance of a multicultural Australia.

Rebecca Sullivan

Rebecca Sullivan is a self-taught cook and has worked with some of the world’s best food producers, academics, activists, and chefs. As food curator, activist, food writer, urban farmer and entrepreneur, Rebecca has worked on many projects any food lover would envy. From launching the Real Food Festival in London to working on Slow Food Nation in San Francisco, farming coffee in Uganda to teaching scientists the art of communications in the Maldives for the United Nations.

Rebecca recently completed her Masters in International Rural Development and Sustainable Agriculture at the Royal Agricultural College in Gloucestershire, UK during which she focused on food security and a sustainable food future and is now undertaking another Masters in Food History at the University of Adelaide.

Rebecca’s obsession with food began in Italy, so it followed course that she would become interested in the Slow Food Movement in which she spent years working with them in the UK and US organising events, campaigns and of course, eating. She is extraordinarily passionate about heritage, tradition, sustainability and the things that we all love - good, clean and fair produce. 

After a decade working overseas, she has re-settled back in Australia and consults to organisations on education and strategy work in and around the food, environment and lifestyle sectors and sustainability. 

Wish Magazine in The Australian has called her "A veritable modern day Mrs Beeton.” 

Damien Coulthard

Damien's role for Warndu incorporates direct relationship building with communities and wild harvesters. This is a hugely important role for the company as it is its core goal to build long term relationships with communities around Australia.  

Damien is from Adnyamathanha country. He grew up in Quorn and Nepabunna South Australia, very connected to his heritage and culture. His passion for teaching and ability to lead started at a very early age when he first began playing sport.

This also lead him to become a High School Teacher, now in his seventh year at Le Fevre High School in Semaphore. He is the coordinator for the South Australian Aboriginal Sports Training Academy as well as sports coordinator for his school. The SAASTA academy focuses on academic learning, achievement and acceleration through sports which he takes great pride in. He is a valued part of his school and very well respected by the staff, students and local community.

As a leader in his community Damien takes on many positions and roles to empower youth and his peers, one of which includes being Captain of his football team, Port Districts. His love for health and wellbeing also inspired him to take on a part-time role as a personal trainer at Pushing Performance. Damien also sits on the SANTS South Australian Native Title Board as a Director. This role puts him directly in touch with local Aboriginal communities working on land rights.
