In Our Nature

Costa Georgiadis is a landscape architect. His work in media began when SBS commissioned the show he co-created Costa's Garden Odyssey in 2009 and has been growing ever since as host of ABC TV's flagship Gardening Australia which he joined in 2012.

Costa Georgiadis is a landscape architect who chartered a course into gardening and growing through his grandfather's market garden, his godfather's farm in Bylong N.S.W. and then studies at the University of N.S.W. This was followed by close to a decade living and working in Europe building rooftop gardens, natural swimming ponds and community composting systems.

In 2019 Gardening Australia won a Logie for Most Popular Lifestyle Show and Costa won the Silver Logie for Most Popular Presenter. He is also known nationally as Costa The Garden Gnome from the successful Get Grubby TV program for children alongside Dirtgirl and Scrapboy.

Costa travels the country in his capacity as an environmental educator visiting schools and communities from Thursday Island in the north to Tasmania in the south, immersing them in the joys of nature's details and how living sustainably and responsibly towards the environment is a fun and engaging process for all generations.

Costa is a story teller who connects the big planetary picture of science and life by accessing the little dots of day to day action and habit. 'Earth Care, People Care and Fair Share’ are the permaculture ethics he threads through his outlook and in a world of great and constant change, the need for adaptability, resilience and flexibility is a current that runs through all of his work everyday. He loves connecting people through plants and the environment.
