St George & Bayside · AS 3660.1
Perimeter and under-slab termite protection installed to AS 3660.1 for new homes and knockdown rebuilds around Connells Bay and Duggan Park, postcode 2221, in the Georges River Council area.
Quick answer
Yes. Connells Point sits within a termite-prone area of the Georges River Council district, so the National Construction Code requires new homes and rebuilds to carry a termite management system. Installation follows AS 3660.1, finished before the slab is poured. We then supply the certifier with a durable notice for the meter box and a matching installation certificate, both needed ahead of the Occupation Certificate.
Termite barriers in Connells Point
Connells Point takes its name from the headland beside Connells Bay on the Georges River, a small residential pocket in postcode 2221 about 16.2 km south-west of the Sydney CBD, inside the Georges River Council area. Connells Point Road runs through the centre, and the suburb sits close to Hurstville Grove, South Hurstville, Blakehurst and Kyle Bay. There is no railway station or major shopping strip here, just streets of established houses running down toward the water. Most building activity is knockdown rebuild work on older blocks, along with granny flats and the occasional duplex split, rather than large new-estate subdivisions, so barrier work is almost always tied to a single custom slab rather than a repeated house-and-land design.
Water is close on several sides of Connells Point, with Connells Bay, Poulton Park and Connells Point Reserve all within the suburb and Donnelly Park sitting right on the Connells Bay shoreline. That waterside setting keeps sub-floor spaces and retaining walls damp for long stretches of the year, which is exactly the kind of ground subterranean termites move through easily. A rebuild on a block that has carried decades of garden beds, paths and old timber near the soil needs the same close attention to slab edges, pipe penetrations and step-downs as a fresh estate lot, because none of that history disappears once the new slab goes in. Getting the barrier detailed before the pour is the only practical time to close those routes.

Local conditions
Three local factors shape how we detail a barrier on a Connells Point block.
Connells Bay, Poulton Park and Connells Point Reserve keep the water table high on much of the peninsula. Damp sub-floors and retaining walls near the shoreline are the conditions subterranean termites favour, so waterside blocks get a full perimeter system rather than a partial edge strip.
Most new work here replaces older full-brick houses on blocks with mature gardens near Duggan Park and Young Place Reserve. Decades of buried timber and garden beds can already be feeding termite activity before the old house comes down, so soil and under-slab treatment matter as much as the edge.
With no station or major shopping centre in the suburb itself, most colony pressure comes from the bushland pockets and reserves between streets rather than a commercial strip. We plan collar counts and the perimeter around each block's own trees and garden beds, not a generic suburb-wide pattern.
What we install here
We work on Connells Point knockdown rebuilds, granny flats added behind existing houses and the occasional duplex split, since the suburb has little room left for new-estate subdivisions. Waffle pod and raft slabs are common on the flatter blocks, with suspended floors and additional piers where a block steps down toward Connells Bay or Poulton Park. Collars go on every pipe penetration before the pour, and the perimeter and any under-slab system are scheduled around your plumber and concreter so the barrier visit never holds up the pour date.
Local knowledge
Duggan Park sits about 0.1 km from the suburb centre and Young Place Reserve about 0.3 km away, both treed pockets close to rebuild sites where garden beds and old timber can already be harbouring termite activity. Donnelly Park, on the Connells Bay shoreline near the sailing club, marks how close the water sits to many blocks. Westfield Hurstville, about 1.9 km off, is outside the suburb itself and has little bearing on barrier work, which is driven far more by the bay-edge ground than by anything commercial.
Georges River Council is the certifying authority for Connells Point. Before signing off the Occupation Certificate, the certifier wants proof the termite work was done: a durable notice fixed inside the meter box, and an installation certificate setting out the products, the protected areas and the installer's details. We prepare both against the approved plans and pass them on with product data and maintenance guidance, so a rebuild or granny flat approval is not left waiting on paperwork.

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.

Connells Point questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. A secondary dwelling, duplex or rebuilt house is treated as a new building under the National Construction Code, so it needs a termite management system installed to AS 3660.1 regardless of how established the block is. If anything, an older garden with buried timber near Duggan Park or Young Place Reserve needs closer attention to soil treatment than a cleared estate lot would.
After the plumber has set out the services and before the concrete pour, which is also when we schedule around waterside blocks that need extra step-downs or retaining near Connells Bay. Book us in as soon as you have a rough slab date so the visit lines up with your plumber and concreter rather than causing a delay.
Sometimes. Where the existing home already has a documented system, we can tie the new slab into it if the detailing and access allow. Where there is no record of the original system, or the two structures are not directly connected, the granny flat gets its own collars, perimeter and certificate so Georges River Council has a complete record for the new dwelling.
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.
