Termite-prone area
A termite-prone area is a site where subterranean termites are a risk. It triggers mandatory AS 3660.1 termite management. How councils declare it and what it means.
Ask Chalkline about this →A termite-prone area is a site where subterranean termites present a risk of attack, which is the trigger that makes a termite management system mandatory under the NCC. It is the threshold question for any new build: if the site is termite-prone, AS 3660.1 termite management is required for the termite-susceptible primary building elements; if it is not, the requirement does not apply.
The NCC trigger
Under NCC 2022 Housing Provisions Part 3.4.1, a termite management system is required where subterranean termites are a risk (verified 2026-05-25, ABCB NCC 2022 Housing Provisions). The Code does not require termite protection everywhere; it requires it where the hazard exists. The practical reality is that most of Australia outside the alpine and very arid regions is treated as termite-prone, so for the great majority of residential sites the answer is yes.
How a site is declared termite-prone
It is not the builder’s call. Local councils declare termite-prone areas through their development control instruments. To confirm whether a specific site triggers AS 3660.1, check:
- the development control plan (DCP) for the area, and
- the conditions of consent on the development approval.
If either declares the area termite-prone (and they almost always do across mainland Australia), the build needs a compliant termite management system.
What it triggers
In a declared termite-prone area, Class 1 and Class 10 buildings with termite-susceptible primary elements must have a termite management system to AS 3660.1. The “termite-susceptible primary elements” qualifier matters:
- A timber-framed house is squarely caught, the structural elements are susceptible.
- A building whose primary structural elements are non-susceptible (for example certain steel-framed or concrete construction) may face reduced requirements, because the elements the rule is protecting are not at risk.
The management system itself can be a physical barrier (graded stone like Granitgard, stainless mesh), a chemical barrier, treated timber, or a combination, all detailed under AS 3660 and explained in termite barriers.
State specifics
Two jurisdictions go further than the baseline:
- Queensland: the termite management system must have a minimum 50-year design life.
- Northern Territory: protection must cover Mastotermes darwiniensis, the giant northern termite, in addition to ordinary subterranean species. This limits the acceptable product list to systems certified against that species.
For a builder
- Check before you price. Confirm the site’s termite-prone status from the DCP and the conditions of consent at the start, not after the slab is poured; the management system is a real line item.
- Assume termite-prone on the mainland. Outside alpine and arid zones, plan for AS 3660.1 by default and confirm rather than assume you are exempt.
- Mind the state rule. A Queensland job needs a 50-year system; a Northern Territory job needs Mastotermes-rated protection. A southern-states spec does not automatically satisfy either.
- It drives a durable notice. Whatever system is installed in a termite-prone area is recorded on the durable notice fixed in the building, and the home still needs ongoing inspections.
Also known as: termite-prone declaration, designated termite area.
