Eastern Suburbs · AS 3660.1
Collars and a continuous perimeter system planned across whole developments on Hillsdale townhouse and duplex infill builds, from the streets near Southpoint Shopping Centre toward Heffron Park.
Quick answer
New construction in Hillsdale does need a termite management system, since Bayside Council sits within a termite-prone area recognised by the NCC. This applies to infill townhouses, duplexes and any new slab, with every penetration collared and the whole system built to AS 3660.1 before concrete closes it in. Your certifier then wants the durable meter box notice and a signed record of the work before approving occupation.
Termite barriers in Hillsdale
Hillsdale was carved out of Matraville in the 1960s and remains a small suburb dominated by units and flats, with relatively few detached houses, centred on Southpoint Shopping Centre's high-rise mixed-use complex on Bunnerong Road. New construction here tends toward infill townhouses and small unit developments on the limited detached blocks that remain, rather than the broad-acre rebuilds seen further out in Sydney, though the odd duplex or secondary dwelling still appears on a larger corner lot. Every one of those projects still needs its own compliant termite management system, checked and certified before the certifier will sign off occupation.
A suburb built mostly on unit and townhouse living changes how a termite barrier gets planned. Shared walls, common driveways and a single large slab footprint mean the perimeter has to be treated as one continuous system across a development rather than lot by lot, since a weak point on one unit can let activity travel into the next. On the smaller number of standalone or duplex sites nearby, established gardens close to Heffron Park bring more typical garden moisture and root growth into play, calling for the usual attention to slab edges and service penetrations.

Local conditions
Three things shape how we plan a termite barrier for Hillsdale's mostly medium-density building stock.
Because so much of Hillsdale is units and townhouses, one unit's weak point in the barrier can become the way termites reach the unit next door through a shared wall or driveway. We plan the perimeter for the whole development rather than treating each unit separately.
The high-rise mixed-use development around Southpoint means some new slabs are large, single-footprint builds with many service penetrations. Collar counts and coordination with the plumber across the whole floor plate matter more here than on a standard house block.
Properties nearer Heffron Park's sports grounds sit close to irrigated turf and mature trees, which can keep soil damper than the surrounding streets. That moisture is exactly what subterranean termites look for when foraging toward a new slab.
What we install here
We work on Hillsdale's infill townhouse rows, duplexes and the occasional unit block slab, and on a shared-wall development the barrier is designed as one system spanning every lot rather than unit by unit. A collar is fitted to every penetration once the plumber has finished the rough-in, and our visit slots in ahead of the pour. A single fixed quote from the plans covers the full job, through to the certificate your certifier requires.
Local knowledge
Our Hillsdale work concentrates around Southpoint Shopping Centre and the surrounding townhouse streets, extending out toward Heffron Park, the Des Renford Aquatic Centre and Bonnie Doon Golf Course. Sites nearest the park's irrigated grounds get closer attention to slab-edge moisture, while the more common townhouse and unit developments near Southpoint are planned around a full, continuous perimeter across the whole site rather than lot by lot.
Bayside Council is the certifying authority for Hillsdale. Before it will issue an Occupation Certificate, it wants a durable notice fixed inside the meter box, plus a signed installation certificate recording the products, the areas protected and the installer. We provide both once our work is complete, along with maintenance guidance suited to whichever building type, unit, townhouse or house, the system was fitted to.

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.

Hillsdale questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. With units in a row sharing walls, driveways and often roof space, we plan the whole development as a single protected footprint rather than a set of separate barriers per lot. That coordination happens with the builder before any work starts on site, so there is no weak point where activity could cross between neighbouring homes.
Yes, a duplex needs its own compliant termite management system, with a collar fitted to every plumbing and service penetration and either a perimeter or an under-slab approach chosen to suit. The certifier still wants the meter box notice and a signed installation record before granting occupation, regardless of how many dwellings share the one site.
Irrigated sports fields and established trees can keep soil in the surrounding streets wetter than average, and a colony foraging for a new food source is naturally drawn toward that kind of ground. Blocks close to the park boundary generally get closer attention to slab-edge detailing, though we still assess every site against its own plans.
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.
