Eastern Suburbs · AS 3660.1
Perimeter termite barriers installed to AS 3660.1 for Malabar rebuilds near Long Bay, between the Randwick Golf Course fairways and the Malabar Headland National Park coastal scrub.
Quick answer
Yes, a rebuild or new home in Malabar needs a termite management system, since the suburb sits in a termite-prone part of the City of Randwick with salt air and sandy soil that suit timber pests generally. The system 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 before the Occupation Certificate.
Termite barriers in Malabar
Malabar sits around Long Bay in the City of Randwick, about 11 km south of the Sydney CBD in postcode 2036, taking its name from the cargo ship MV Malabar, wrecked nearby in 1931. It is mostly residential, but large parcels of land are taken up by the Randwick Golf Course, the ANZAC Rifle Range and the Long Bay Correctional Centre, with a small group of shops trading along Prince Edward Street and Malabar Headland, with its wartime fortifications, forming the northern side of the bay. Most of our work in Malabar is a knockdown rebuild on an established block close to one of these large open landholdings.
Streets in Malabar run close to the beach, the headland scrub and the fairways, so a rebuild here sits within reach of several different moisture sources at once. Sea air and sandy soil keep sub-floors and bathrooms damp, conditions that suit subterranean termites as much as cockroaches and silverfish, and the coastal heath along Malabar Headland holds established colonies with a fairly direct path toward nearby houses. Streets backing onto the headland or the rifle range land get the most attention in our quotes, because that is where termite and timber-decay risk in Malabar is highest.

Local conditions
Three conditions push termite and timber-decay risk higher on some Malabar streets than others.
Malabar Headland National Park holds established termite colonies in its coastal heath, and streets backing onto that boundary or the adjoining rifle range land sit closest to that pressure. Those blocks usually need a full perimeter rather than a minimal strip.
Sea air and sandy soil across Malabar keep sub-floors and bathrooms damper than an inland Randwick block, and that moisture is favourable to subterranean termites as well as timber decay generally. We factor sub-floor ventilation into every rebuild we quote.
Randwick Golf Course borders parts of the suburb, and its irrigated fairways keep the ground damper near several boundaries. Blocks close to the golf course get the same attention to moisture and perimeter detail as those nearer the headland.
What we install here
We work on Malabar knockdown rebuilds, extensions and granny flats on established blocks near the golf course, the headland and the beach. We install physical or chemical perimeter systems and under-slab membrane suited to sandy, salt-affected ground, with particular care at sub-floor ventilation given the local moisture. One fixed quote from your plans covers every stage, scheduled around your builder's pour date so the barrier visit does not hold things up.
Local knowledge
Our Malabar work concentrates around Boulevarde Reserve and Malabar Beach, where sea air and sandy dunes sit close to many homes, and along the edge of Malabar Headland National Park, where coastal heath brings termites and other bush pests closer to nearby streets. Blocks near the Randwick Golf Course boundary get similar attention, since irrigated fairways add moisture of their own close to the perimeter.
Malabar is certified through the City of Randwick, which requires the standard termite documentation before it will issue the Occupation Certificate: an installation certificate lists the products used, the installer's licence and the protected areas, while a durable notice goes up inside the meter box. We provide both, along with maintenance advice suited to a salt-affected, sandy-soil property.

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.
Paperwork

Malabar questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Often, yes. Coastal heath along the headland holds established termite colonies, so streets backing onto that boundary or the adjoining rifle range land usually get a full physical perimeter rather than a minimal treated strip, with attention to the specific side of the block facing the bush. That keeps the whole process simple for you and your builder.
It affects sub-floor ventilation more than the barrier product itself. Salt air and sandy ground keep sub-floors and cavities damper than an inland suburb, so we pay close attention to ventilation and drainage detailing alongside the standard collars, membrane and perimeter. It also keeps your certifier's paperwork straightforward and complete.
It can mean slightly damper ground near that boundary, from irrigated fairways rather than natural bushland. We assess the actual distance and exposure on your plans and recommend a physical or chemical perimeter based on what we find, not a blanket rule. Feel free to ask us anything else not covered here.
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.
