Eastern Suburbs · AS 3660.1
Termite barriers installed to AS 3660.1 for Little Bay's remaining new-build stages and heritage conversions on the former Prince Henry Hospital site, backing onto Botany Bay National Park.
Quick answer
Yes, a new home or townhouse in Little Bay needs a termite management system, because the suburb sits in a termite-prone part of the City of Randwick and the NCC requires a compliant system regardless of how recently the area was developed. It is installed to AS 3660.1, with collars and under-slab work completed before the pour, and the durable notice plus installation certificate supplied to your certifier.
Termite barriers in Little Bay
Little Bay is a small suburb in the City of Randwick, about 13 km south of the Sydney CBD in postcode 2036, built mainly on the former Prince Henry Hospital site, which closed in 2001 and was redeveloped for housing. Nineteen heritage hospital buildings were retained and now sit among newer townhouses, apartments and detached houses, and the suburb has its own sheltered beach, two golf clubs and a border with Botany Bay National Park. Our work here covers both remaining new-build stages within the estate and conversions of the older heritage buildings into residential use.
That mix is unusual for a coastal Randwick suburb, because most of Little Bay's housing is recent, yet it sits directly against coastal heath, headland and irrigated fairways rather than other streets. New homes still need a termite management system checked and kept intact as owners landscape, and the converted heritage buildings bring older roof spaces and brickwork that need their own attention. Coastal heath and headland vegetation along the national park boundary hold termite activity close to some blocks, while golf course irrigation keeps other parts of the estate damper than a typical infill site.

Local conditions
Three things set termite risk in Little Bay apart from an older, established Randwick suburb.
Little Bay borders Botany Bay National Park, and the coastal heath and headland vegetation along that edge hold termite activity in ways an older, fully built-out suburb usually does not. Blocks closest to the park boundary get a full perimeter rather than a minimal strip.
Two golf clubs sit close to Little Bay's housing, and their irrigated fairways keep nearby ground damper than the rest of the estate. That moisture is favourable to subterranean termites foraging toward a new or converted slab.
Nineteen retained Prince Henry Hospital buildings sit among newer housing, and any conversion or extension of those older structures needs its own termite check, since aged roof spaces and brickwork can already carry activity that a purely new build would not have.
What we install here
We work on remaining new-home and townhouse stages within the Little Bay estate, as well as extensions and conversions of the retained heritage hospital buildings. New slabs get under-slab membrane, collars and a physical or chemical perimeter to AS 3660.1, while heritage conversions are assessed on their existing sub-floor and roof space before we recommend a system. One fixed quote from your plans covers every stage, scheduled around your builder's pour date.
Local knowledge
Our Little Bay work concentrates around Macartney Reserve and Chifley Sports Reserve, where turf and open ground sit close to several new-build boundaries, and along the edge toward Cape Banks Aquatic Reserve, where the coastline turns into national park. Blocks nearest that bushland and headland get the most attention at the perimeter. Closer to the retained heritage buildings, our focus shifts to the existing roof space and sub-floor rather than a fresh slab.
Little Bay is certified through the City of Randwick, which requires the same termite documentation on a new build or heritage conversion as anywhere else: a durable notice fixed in the meter box, and an installation certificate naming the products used, the areas protected and the installer's licence, both needed before the Occupation Certificate is issued. We provide both as soon as the barrier work is complete.

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.

Little Bay questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. Age of the estate does not change the requirement, since the NCC applies to any new home on termite-prone land. Little Bay also backs onto coastal heath and national park, so we do not treat it as lower risk simply because most of the housing is recent. We are glad to answer further questions once we are on site.
We start by inspecting the existing roof space, brickwork and any timber sub-floor for signs of established activity, since these buildings are decades older than the surrounding housing. From there we recommend a system suited to what the structure actually needs rather than a standard new-build package. This keeps everything properly documented for future reference too.
It usually means a full physical perimeter rather than a minimal strip, since coastal heath and headland vegetation along that boundary can carry termite activity closer to a new slab than housing further inside the estate. We assess your actual boundary as part of the quote. Just get in touch and we will talk through the details.
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.
