New build termite protection on the Gold Coast.
The NCC mandates a termite management system for every new home built in the Gold Coast LGA. What goes in, who installs it, what the durable notice must say, and why the subtropical climate means one system is rarely enough.
NCC and AS 3660.1 obligations for new builds.
NCC Volume Two Part 3.1.3 — the mandatory requirement.
The National Construction Code (NCC) Volume Two — which governs Class 1 (houses, townhouses) and Class 10 (sheds, garages, carports) buildings — contains Part 3.1.3, the termite risk management provisions. The performance requirement is that the building must be designed and constructed so that termite entry is impeded and any termite activity can be detected. In practice, this means:
- A compliant termite management system must be installed before the frame is enclosed or the slab is poured, depending on the system type.
- The system must comply with AS 3660.1-2014 Termite management — New building work.
- The installer must be a QBCC-licensed pest management technician — not just the builder or slab contractor.
- A durable notice must be installed in the meter box (or permanently accessible location) at the time of building handover.
AS 3660.1-2014 — the technical standard.
AS 3660.1 specifies how each approved termite management system must be designed and installed. It covers: the gap tolerances permitted in physical barriers, the minimum dilution rates and application volumes for chemical treatments, the design of reticulation pipe networks, and the inspection access requirements that must be maintained post-construction.
The standard also requires that the system provide complete coverage — no untreated pathways. This is harder than it sounds on a complex slab design with multiple post-pour penetrations, step footings, and internal wall junctions. A builder who specs only a basic perimeter treatment and calls it done is commonly leaving gaps at service penetrations and expansion joints.
Builder duties vs owner duties.
The builder is responsible for ensuring a compliant system is installed before handover. Once you take possession, the ongoing management — annual inspections, barrier replenishment, durable notice preservation — is your responsibility as the owner. Many buyers assume the builder’s defects liability period covers termite damage; it does not unless the infestation resulted from a failure in the installed system itself.
Physical barriers, reticulation, and perimeter chemical.
Pre-pour chemical reticulation system.
The most common system on the Gold Coast for slab-on-ground construction. A network of perforated pipes is laid in the footprint of the slab and perimeter zone before the concrete is poured. The system is then charged with termiticide (typically Termidor or Premise) under the cured slab. The pipes remain permanently in place for future replenishment when the chemical service life expires.
- Advantages: Covers the full under-slab zone; replenishable without breaking concrete; suited to Gold Coast slab-on-ground standard construction.
- Limitations: Relies on chemical integrity over time; pipes can clog or be crimped during pour; the system must be connected to surface ports for replenishment access — these must not be covered by landscaping or paving.
- Cost: $1,800–$3,500 installed for a standard Gold Coast home footprint.
Physical barriers — stainless mesh, graded stone, and sheet membrane.
Physical barriers block termite penetration through or around the slab without relying on chemistry. Three main types are approved under AS 3660.1:
- Stainless steel mesh (Termi-Mesh): 316-grade stainless steel mesh with apertures smaller than the workers’ mandibles. Applied to slab edges, penetrations, and cavity walls. Highly durable — does not expire — but must be installed with zero gaps. Common on high-end Gold Coast builds.
- Graded granite stone (Granitgard): A bed of 2–5 mm granite particles installed in a continuous band around and under the slab. Particles are too heavy for termites to move and have no gaps large enough for worker passage. Low maintenance; does not expire. Requires correct grading and compaction.
- Sheet membrane (Kordon, Thermakraft): A treated polymer sheet installed under the slab and lapped up the slab edges. Includes termiticide impregnated into the sheet material. Low installed cost but relies on the sheet remaining intact — any penetration or tear is a vulnerability.
Physical barriers are often used in combination with a perimeter chemical treatment because no physical system covers 100% of penetration pathways in a complex build. See our AS 3660 barrier types guide for a full comparison.
Perimeter chemical soil treatment only.
A perimeter-only chemical treatment is the minimum-compliant option for some construction types. Termiticide is trenched-and-rodded into the soil around the external perimeter of the slab after construction. It does not cover under-slab pathways. On the Gold Coast, where Coptotermes pressure is high and construction details are complex (step footings, cavity walls, multiple penetrations), we advise against relying on a perimeter treatment alone. It is best used as a supplement to a physical or reticulation system.

The durable notice: what it must contain.
The durable notice is a legal requirement under both the NCC and AS 3660.1. It must be installed in the meter box or an equivalent permanently accessible location and must contain the following information:
- Type of termite management system. E.g. “pre-pour chemical reticulation system” or “stainless steel mesh physical barrier.”
- Product name and active constituent. E.g. “Termidor SC, active constituent: fipronil 100 g/L” or “Termi-Mesh 316-grade stainless steel.”
- Date of installation. This is the start point for the service life clock.
- Required maintenance interval. E.g. “Annual inspection required. Chemical replenishment required within 8 years of installation date.”
- Installer contact details. QBCC licence number and business name.
If you are buying a new build or a recently built home and there is no durable notice in the meter box, that is a building-compliance issue. The seller has an obligation to provide it. Request it in writing before settlement.
If you cannot locate the durable notice for your existing home and suspect a chemical system was installed, our post-construction protection service includes a system identification inspection — we locate the reticulation access ports and identify the system type where possible.
Subtropical climate and the case for a combined system.
Year-round termite activity.
Unlike Melbourne or Adelaide where soil temperature drops below 12°C in winter and termite foraging substantially slows, the Gold Coast’s subtropical climate means Coptotermes acinaciformis colonies are active and foraging every month of the year. This means a new-build barrier is exposed to termite pressure from day one, not just in summer. Systems that rely on a single mechanism — chemical only, or physical only — face sustained pressure across every construction detail.
High-set Queenslanders and timber-frame builds.
Older timber-framed high-set homes that pre-date NCC termite provisions have no built-in barrier at all. When these properties are renovated or extended, a new-build termite management system must be installed for the new work. On a high-set with a sub-floor, the protection strategy is different to slab-on-ground — typically a combination of soil treatment to the ground plane and physical barriers to the stumps or piers.
New build + annual inspection = the complete picture.
NCC-compliant protection at construction is the foundation. Annual AS 3660.2 inspections are the ongoing management layer. Neither replaces the other. A barrier without inspections means you won’t know when the chemical has expired or when a pathway has opened at a service penetration. Inspections without a barrier mean termites have an easy path in during the year between visits.
The Gold Coast’s subtropical pressure — H4 hazard zone, Coptotermes dominance, year-round activity — is why experienced builders and pest technicians here recommend a combined system: physical barrier at the slab plus perimeter chemical, supported by annual inspections and a baiting station perimeter where risk warrants it. This is not overselling. It is an honest response to the local environment.
What to confirm at new build handover.
- Durable notice is in the meter box. Confirm system type, product name, installation date, and maintenance interval are all legible.
- Certificate of installation provided. The QBCC-licensed installer must provide a written certificate. Builder’s completion certificate is not a substitute.
- Reticulation access ports identified and marked. You need to know where the recharge access points are before landscaping and paving covers them.
- Inspection access corridors maintained. AS 3660.1 requires that the perimeter be kept accessible for annual inspection — no permanent structures within 600 mm of the slab edge without a barrier. Confirm with your landscaper before they start.
- Annual inspection booked. First annual inspection should be 12 months from handover. Book it now — it confirms the system is performing and documents your cover start date.
- Baiting station option considered. For lake-edge, canal-adjacent, or high-risk sites, adding a perimeter baiting system (Sentricon Always Active) in the first year gives an additional layer of colony detection and elimination. See our baiting systems service for details.
Frequently asked questions.
Is termite protection mandatory for a new Gold Coast home?
Yes. The National Construction Code (NCC) Volume Two Part 3.1.3 requires that all new Class 1 and Class 10 buildings in termite-active areas — which includes the entire Gold Coast LGA — include a compliant termite management system. AS 3660.1 defines the technical requirements. It is a building permit condition, not optional.
What termite protection systems are approved under AS 3660.1?
AS 3660.1 approves three system categories: physical barriers (stainless steel mesh, graded stone, sheet membrane, or a combination), chemical soil treatment (applied pre-pour or perimeter), and reticulation systems designed for periodic chemical replenishment. A combined physical-plus-chemical approach is standard on the Gold Coast because a single system rarely covers all construction details comprehensively.
What is the durable notice in the meter box for new builds?
NCC and AS 3660.1 require a durable notice to be installed in the meter box (or another permanently accessible location) at handover. It must state: the type of termite management system installed, the product name and active constituent, the installation date, and the required maintenance interval. This notice is the homeowner’s reference for ongoing management and warranty conditions.
How much does new-build termite protection cost on the Gold Coast?
A pre-pour chemical reticulation system for a standard Gold Coast slab home costs $1,800–$3,500 installed. Physical barrier (stainless mesh or sheet membrane) for a standard footprint is $2,500–$5,000 depending on slab design complexity. Perimeter chemical treatment only is $1,200–$2,500. Most builders include a basic reticulation system in the build contract; the quality and completeness varies significantly.
Does a new build still need annual termite inspections?
Yes. AS 3660.2 requires annual inspections regardless of the construction date or the type of barrier installed. For a reticulation system, the annual inspection also determines when the chemical requires replenishment — typically every 5–10 years. For physical barriers, the inspection confirms the barrier has not been bridged by soil movement, landscaping, or construction changes.
