Use the following formula to calculate the diameter of the tree trunk: Diameter = Tree Circumference divided by 3.14159. For example, if your tree, at a height of 1500mm, is 1256mm around (the circumference) then it is approximately 400mm in diameter (1256mm divided by 3.14159 = approximately 400mm).
If a tree overhangs into a neighbouring property, the owner or resident of the neighbouring property is allowed to prune the tree, as long as they do not kill or destabilise the tree.
A permit is required from Council to remove or lop branches from a tree listed on the Significant Tree Register and deemed significant under the Local Law.
