A suburb in the middle of being rebuilt
Kirrawee's old brick pit site and the land around the station have driven a long run of redevelopment, and the flow-on through the surrounding streets has been steady knock-down rebuilds and duplex work on what were modest post-war blocks.
That makes the tree work here different to anywhere else in the Shire. Elsewhere the question is usually about an ageing tree and a worried owner. In Kirrawee it is frequently about a healthy tree that is now in the wrong place because the house is about to change shape.
Trees and building consent
The sequence that works is boring and it saves money. Identify the trees before the design is finalised. Have the ones you intend to remove shown on the plans so the consent covers them. Have the ones you intend to keep assessed, with a tree protection zone specified. Then build.
The sequence that goes wrong is a demolition contractor discovering a protected tree on the day. Sutherland Shire Council's tree controls do not pause for a build program, and removing a protected tree without approval is an offence with real penalties attached. The removal page explains how the approval question is assessed before quoting.
Retained trees die slowly
The damage that kills a retained tree rarely happens with a chainsaw. It happens when the excavator parks over the root zone for a fortnight, when a service trench cuts three structural roots on one side, or when the finished level is raised 300mm over the root plate with fill.
None of those show up immediately. The tree declines over two to four summers and fails in a storm after the builder has long gone. If you are keeping a tree through a build, keep machinery off the root zone and hand-dig anything inside it.
What is actually growing here
The older backyards carry the same mix as neighbouring Sutherland: camphor laurel, liquidambar, brush box and jacaranda from mid-century plantings, plus retained eucalypts on the blocks that were never fully cleared. Cocos palms in front gardens are a constant, and are usually straightforward to deal with — see the palm removal page.
Access is generally reasonable. Streets take a truck, most blocks have a usable side path, and the flat ground means stump grinding is limited by services rather than by rock, unlike the slopes at Gymea.

Frequently asked questions
The builder says the tree has to go — is that enough?
No. A builder's opinion is not an approval. If the tree is shown for removal on the approved plans, the consent covers it; if it is not shown, it is still protected and needs its own approval from Sutherland Shire Council. Check the consent conditions and the landscape plan before demolition starts, because retrospective applications are expensive and sometimes refused.
What is a tree protection zone on a building site?
It is the fenced area around a retained tree that machinery, materials and spoil must stay out of, usually specified in the consent conditions and set by an arborist. Compacting soil inside it or cutting roots for a trench can kill a tree years after the build finishes, and the consent can require a bond. Take it seriously even when it is inconvenient.
Who pays when a boundary tree is damaged during a build?
Whoever caused the damage, and that gets ugly quickly. Before excavation near a shared boundary, photograph the tree, know where the trunk centre sits relative to the boundary, and talk to the neighbour. A tree straddling the line is owned by both parties and neither can remove it unilaterally, regardless of whose side the mess falls on.
