Rachel Kernaghan
ecologist AND educator


Rachel Kernaghan is a keen educator and trained teacher who has been working and volunteering in environmental education for the last 10 years. She is a local Northern Beaches mum who has been teaching about ecology and sustainability, locally with OzGREEN, Auseco, Manly Vale Community Garden and local schools.

Over the last 10 years, Rachel has dedicated her teaching energy to students of all ages exploring how to grow their own food, compost their food waste and understand more about their relationship with their natural environment and the bigger sustainability picture. Rachel has also been educating members of the local community about the various ways to reduce the use of chemicals in homes including household chemicals, personal care products and pesticides/fertilisers in family food.

Rachel’s passion and energy for reducing waste and educating others about these issues, especially her work with local schools, allows us to expand our reach even further into the community.



Adam Tilley spent most of his late teens and 20s pursuing a career in journalism and media, but 3 years ago his passion for ecology and the environment was awoken after attending a local Permaculture course. Adam began volunteering at Kimbriki Resource Recovery Centre, devoting as much time as he could to maintaining the magnificent gardens that Peter and the team at Kimbriki had created, to educate and inspire the residents of the Northern Beaches Council, and beyond.

After almost 2 years, Adam was given the opportunity to join the Eco House and Garden team at Kimbriki. The knowledge he had gained while volunteering enabled him to further his desire to share what he had learned with others. Adam began working alongside Peter in the Kimbriki pilot school program where they worked closely with Terrey Hills and Mona Vale Public Schools to educate and ultimately inspire children to embrace the principles of Permaculture and sustainable living, through in-school composting and veggie garden projects.

Recently Adam has also been conducting tours of the Kimbriki site which gives him even more opportunity to share his passion for the environment and ecological living.
