A Tree Preservation Order adopted by Ku-ring-gai Council in 2006 stipulates a tree, whether native or exotic, of 5m or more in height or with a trunk width of 150mm or more at ground level requires council approval for its removal or for any pruning work. Trees or branches that are dead, directly over roof lines, within half a metre of electricity wires or within 3m of an existing dwelling do not require council consent for their removal.
General Notes on Councils:
The pruning or removal of any trees on public land, parks, bushland or Heritage Items need special permission from ALL councils.
The Noxious Weeds Act 1993 lists trees not requiring permission to remove.
