At the free event on Sorry Day, Aboriginal and non-Aboriginal people can wander through the garden of fruit trees, bush tucker, vegetable beds, herbs, and native plants developed by locals, for locals.
Mr Olive, star of TV series The Outback Cafe, will perform a live demonstration and prepare a lunch featuring native herbs and spices.
There will also be a Welcome to Country, cultural performance, koala petting, snake holding and community art and a Hunters and Gatherers Scavenger Hunt will begin at 10am, with a $500 cash prize to the winning team (register by 5pm May 23).
Health resources will be available.
The Beat It! Live Longer program, which aims to promote lifestyle change to reduce the prevalence of chronic disease, has built the garden to help Aboriginal people to access, and prepare healthy foods with support from the State Government and the City of Gosnells.
