Sutherland Shire · AS 3660.1
Collars, membrane and perimeter barriers fitted on Caringbah South rebuilds along the Port Hacking peninsula, between Burraneer Bay, Yowie Bay and the national camellia garden reserve.
Quick answer
Yes, a new or rebuilt home in Caringbah South needs a termite management system, since the peninsula sits within a termite-prone part of the Sutherland Shire regardless of which bay the block faces. AS 3660.1 governs the installation, with collars fitted before the pour or footings go in. Sutherland Shire needs a durable notice and matching installation certificate before it will grant occupation.
Termite barriers in Caringbah South
Caringbah South sits on a peninsula along the north shore of Port Hacking, about 22.1 km south of the Sydney CBD. It shares postcode 2229 with Caringbah, which borders it to the north, and it was declared a separate suburb in 2008. It is in the Sutherland Shire council area. The peninsula forms the eastern edge of Burraneer Bay and the western edge of Yowie Bay, with Lilli Pilli, Dolans Bay and Port Hacking to the south, and the suburb is mainly residential, with a small cluster of cafes and professional services on Port Hacking Road South. It also holds the E. G. Waterhouse National Camellia Garden and the heritage-listed Fernleigh house.
Established gardens, mature trees and water close by give Caringbah South a distinct mix of conditions for a new termite barrier to account for. Termites and possums are drawn to the mature tree cover found across many blocks, spiders shelter in the garden beds that come with such established plantings, and rodents and mosquitoes turn up more often near the bays after rain. A rebuild on this peninsula needs to consider what your particular property backs onto, whether that is bushland, a bay or simply another well-planted backyard, since each of these settings pulls a slightly different kind of pest pressure toward the new slab.

Local conditions
Three things drive termite and pest risk on a Caringbah South block, and each shapes how the barrier is planned.
Wattlebird Bushland Reserve is the kind of bushland where termites and funnel-web spiders are naturally at home, and blocks backing onto it need the perimeter treated as seriously as the street frontage. Foraging termites have little distance to travel from reserve bushland to a nearby slab.
Properties facing Burraneer Bay or Yowie Bay deal with damp gardens and mosquitoes that build up after rain, conditions that also keep soil near the slab edge wetter for longer. Waterfront rebuilds get closer attention to drainage as part of the barrier plan.
Long-established plantings across the peninsula, including around the camellia garden, give possums and spiders plenty of cover and can carry decades of buried timber in older garden beds. A rebuild here often needs soil treatment worked in alongside the standard slab-edge system.
What we install here
Knockdown rebuilds and renovations make up most of our work on the Caringbah South peninsula, priced from the plans to account for whichever bay, reserve or garden setting the property backs onto. Suspended floors are common on the sloping blocks closer to the water, with slab-on-ground further inland, and every penetration gets a fitted collar ahead of the pour or footing pour. One written quote covers the whole property, including any pool area or outbuilding.
Local knowledge
Castelnau Street Reserve, about 0.1 km away, has trees and leaf litter that shelter ants, spiders and rodents close to nearby homes. Wattlebird Bushland Reserve, roughly 1.0 km off, is the kind of bushland where termites and funnel-web spiders are naturally at home. Caringbah Shopping Village and Caringbah station, both about 1.0 to 1.3 km away, bring rats that feed around shops and rail drains, while homes on the bay sides deal with damp gardens and mosquitoes after rain.
Sutherland Shire certifies building work across Caringbah South, and occupation is not granted until two records are on file: a notice permanently displayed in the meter box, and a certificate naming the products, the areas treated and the licensed installer. Once the termite management system is complete we send both through without delay, whatever part of the peninsula the property sits on.

Systems we install
Every photo below is from one of our own Sydney jobs. We look at your slab design, site and budget, then recommend a system or a combination.
01A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
A termite barrier isn't a single visit. Each part goes in when the site is ready for it, and we fit around your plumber, concreter and bricklayer.
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.
Compare systems
Both can meet AS 3660.1. The best choice depends on your slab type, what surrounds the house and how much ongoing upkeep the owner wants.
Physical protection
Entry-point protection
Soil protection
Top-up protection
Most of the Sydney builds we work on use a combination: physical collars on every penetration plus a physical or chemical perimeter.
For builders & developers
Builders, developers and owner-builders get a fixed quote from plans, a technician who turns up when the site is ready, and paperwork that never holds up sign-off.
Consistent pricing across lots, one point of contact and a full document set for every dwelling.
Missing durable notices and unclear install records are a common reason Occupation Certificates get held up. We hand everything over together so your certifier has it all in one go.

Caringbah South questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes, bushland reserves like this hold established termite and funnel-web spider activity naturally, and blocks close by have less distance for that activity to travel before reaching a house. We give the perimeter on reserve-facing boundaries the same level of attention as the street frontage rather than treating it as a lesser concern.
Blocks facing Burraneer Bay or Yowie Bay tend to have damper gardens and soil, particularly after rain, and moisture like that tends to draw foraging termites closer to a new slab than they would otherwise travel. The AS 3660.1 system itself does not change, but a waterfront site gets more thought given to how the block drains before we finalise the plan.
Not necessarily, but established plantings and older garden beds can carry buried timber that has supported termite activity for years, so we check the soil around any trees or beds being kept before finalising the plan. That way the barrier accounts for what stays on the block, not just the new slab.
In most cases, yes. The National Construction Code requires a termite management system for new houses and outbuildings in termite-prone areas where the primary building elements can be damaged by termites. Sydney is termite-prone, so the system is installed to AS 3660.1 and your certifier asks for the installation certificate and durable notice before the Occupation Certificate is issued.
It depends on slab area, perimeter length, the number of pipe penetrations, the system chosen, site complexity and how many visits the build needs. Send us the plans and we return one fixed written quote covering every stage. Quoting is free.
