City of Logan Councillors Natalie Willcocks and Jon Raven at the new koala conservation reserve in Greenbank. City of Logan has strengthened its reputation as a green and sustainable city by acquiring a key parcel of koala habitat for conservation. A 212-hectare property at Greenbank was chosen for its high ecological value and importance to the health of the Oxley Creek catchment. It adjoins Cockatiel Park and Platypus Reserve and is close to Spring Mountain Forest Park, Spring Mountain Reserve and the White Rock-Spring Mountain Conservation Estate in Ipswich. A small tributary to Oxley Creek runs through the property. Environment Chair, Deputy Mayor Jon Raven said the purchase of the property would benefit the city for generations to come.
