Different rock, different trees
South of Minnamurra the geology changes. The Kiama district sits on basalt, weathered into deep red volcanic soil, and it is the reason this stretch became dairy country and the reason its trees are the size they are. The same species that grows to fifteen metres on a Corrimal sand profile will make twenty-five here with a trunk to match.
Saddleback Mountain behind the town, the Minnamurra rainforest to the west and the headlands around the Blowhole give the district an unusual mix — remnant subtropical rainforest, exposed coastal planting and rich pasture, sometimes within a kilometre of each other.
The trees that define the area
Moreton Bay and Port Jackson figs are the signature trees, both in the old streets and as remnant paddock specimens. They are enormous, long-lived, and almost always worth keeping. The problems they cause are root problems — lifted paths, cracked slabs, invaded stormwater — and those are rarely solved by removing the tree, which councils here will scrutinise closely in any case.
Illawarra flame trees are the other one people ring about, usually in November when the display makes them notice it. Cabbage tree palms, coachwood and jackwood in the gully remnants, blackbutt and turpentine on the slopes, and the usual camphor laurel where nothing has been managed.
Kiama Municipal Council
Kiama runs its own tree controls. Written approval is generally required before removing or substantially pruning a protected tree, with exemptions for listed weed species, small trees and emergencies. Given the number of significant trees in the district, applications for mature natives and large figs are commonly supported by an arborist report, and it is worth budgeting for that rather than being surprised by it.
The boundary with Shellharbour around Minnamurra catches people out. If you have neighbours who dealt with Shellharbour council last year, that does not mean your lot is in the same LGA.
Wind, exposure and access
The headlands and the coastal strip around Kiama and Gerringong take the full force of a southerly with nothing in front of them. Exposed specimens carry asymmetric crowns and accumulate deadwood on the windward side, so regular deadwooding does more for safety here than reduction work does.
Access varies. Town blocks around the old centre are tight, with narrow lanes and cottages close to the street, and often need a crane or a climb-and-carry approach. Rural blocks out toward Jamberoo have room for anything. Free-draining basalt also means the ground stays workable after rain far longer than the Dapto clay does, so weather delays are less of an issue.

Frequently asked questions
Which council do I apply to in Kiama?
Kiama Municipal Council, which is separate from both Wollongong and Shellharbour and runs its own tree management controls. The boundary sits around Minnamurra, so properties a few streets apart can fall under different councils. Confirm which one your lot is in before lodging anything, because the forms and thresholds differ.
Why do trees get so big around Kiama?
Basalt. The red volcanic soils through the Kiama and Jamberoo district are deep, fertile and free-draining, and they grow figs, flame trees and eucalypts to a size you rarely see on the sandstone-derived soils further north. It is the same soil that made the district dairy country, and it has the same effect on backyard trees.
Can a big fig be pruned instead of removed?
Usually yes, and usually it should be. A mature Moreton Bay or Port Jackson fig is a significant tree and councils treat it that way. Crown reduction, deadwooding and selective limb removal can resolve most conflicts with a roof or a driveway. Root problems in paths and drains are a separate issue and need engineering advice as much as arboricultural advice.
