Termite Inspection Adelaide: The AS 3660 and AS 4349.3 Guide

A termite inspection in Adelaide is a structural-risk assessment of the building, guided by AS 3660.2-2017 and reported following AS 4349.3-2010. AS 3660.2 calls for regular inspections no more than 12 months apart, with shorter intervals on higher-risk sites. A standard residential inspection takes 60–90 minutes, costs $180–$350, and produces a written report covering subfloor, internal timbers, roof void, external surrounds and outbuildings within 30 metres of the building.

That is the answer in one paragraph. The rest of this guide is the long version — what each of the three governing standards actually says, when each one applies to your home, what the inspection physically covers, what a thermal-only inspection misses, and what to do with the report once it lands.

Why this guide exists

Most Adelaide pest control sites cite “the Australian Standards” without naming the parts, the editions, or the scope of each. That makes the inspection look generic — and a generic inspection is what a homeowner gets when nobody is checking which standard the inspector is actually working to.

The three documents that govern termite work in South Australia are not interchangeable:

• AS 3660.1-2014 — Termite management — Part 1: New building work. The construction-stage standard.
• AS 3660.2-2017 — Termite management — Part 2: In and around existing buildings and structures. The standard that covers every existing home.
• AS 4349.3-2010 — Inspection of buildings — Part 3: Timber pest inspections. The standard that governs the report itself.

A competent inspection on an existing Adelaide home cites Part 2 of AS 3660 for the methodology and AS 4349.3 for the report form. A new-build sign-off cites Part 1 of AS 3660. A pre-purchase report cites AS 4349.3 with the additional pre-purchase scope. If a quote you’ve been sent doesn’t say which standard applies — that’s the first question to ask.

AS 3660.1-2014: the standard for new building work

AS 3660.1-2014 sets the requirements for the design and construction of subterranean termite management systems for new buildings and new building work in Australia. The 2014 edition is current, and the National Construction Code references AS 3660.1 for termite management in new buildings.

What Part 1 governs:

• The chemical barrier systems acceptable at slab construction (perimeter sprays, soil reticulation pipework, treated zones)
• The physical barriers acceptable at slab construction (stainless steel mesh products, graded stone, ant capping over piers)
• Integration with slab design under AS 2870 (Residential slabs and footings) and AS 3600 (Concrete structures)
• The durable notice that must be installed in the meter box recording the system installed, the installer, the chemical (where used), and the next inspection date
• Site management precautions to reduce termite risk during and immediately after construction

When Part 1 applies to you:

• You are building a new home in Adelaide
• You are extending or substantially renovating an existing home (the new work falls under Part 1, even if the existing house is much older)
• You are settling on a brand-new home and the durable notice should already be in the meter box
• You are signing off a builder’s defect-liability period and the termite system is part of the practical-completion checklist

Part 1 does not apply to inspections of existing buildings. That is what Part 2 is for.

AS 3660.2-2017: the standard for existing buildings

AS 3660.2-2017 is the companion standard for buildings already standing. The Standards Australia revision (May 2017, replacing the 2000 edition) tightened the inspection methodology, the documentation requirements, and the recommended inspection-frequency wording.

What Part 2 governs:

• The methodology for inspecting an existing building for termite activity, conducive conditions, and structural risk
• The chemical retrofit options acceptable on existing buildings (soil treatments, foam, dust, baiting)
• The physical retrofit options acceptable on existing buildings (chemical reticulation pipework retrofitted around the slab, stainless steel mesh applied during partial reconstruction)
• The documentation the inspector must produce (severity grading, photographs, recommended treatment, recommended re-inspection interval)
• The recommended inspection frequency — at intervals of not more than 12 months for most properties, with the inspector authorised to recommend shorter intervals on high-risk sites

That 12-month interval is not a marketing line. AS 3660.2-2017 calls for regular inspections no more than 12 months apart (AEPMA’s notes on the 2017 revision summarise this).

When Part 2 applies to you:

• Your home was built before modern termite-management standards and has no termite management system from construction
• Your home is newer and has an existing termite management system that needs ongoing inspection
• You have had a previous termite treatment that needs regular follow-up inspection (and any product warranty may depend on it)
• You have seen a sign of termite activity (mud tube, frass, alate swarm, hollow timber) and need a positive ID before treating

Most of inner Adelaide’s housing stock — Norwood villas, Unley bungalows, Prospect Californians, Walkerville and Semaphore character homes — was built long before modern termite-management standards. AS 3660.2 is the relevant standard for those homes today. (More on that under “Older Adelaide homes” below.)

AS 4349.3-2010: the standard for the report

AS 4349.3-2010 — Inspection of buildings — Part 3: Timber pest inspections — sets the form and scope of the report itself. AS 3660.2 says how to inspect; AS 4349.3 says what the report has to contain. The two work together. A termite inspection in Adelaide is conducted to AS 3660.2-2017 and reported to AS 4349.3-2010.

What AS 4349.3-2010 requires the report to include:

• Scope of the inspection (what was checked)
• Areas inspected (subfloor, internal, roof void, external, outbuildings)
• Areas not accessible (a clean report on a half-inspected property isn’t worth much)
• Findings, with severity grading
• Photographs of every finding
• Plain-English summary
• Recommendations (treatment, re-inspection, monitoring)
• Susceptibility assessment of the building to timber pests
• Further investigations required, where the inspector cannot reach a finding

What AS 4349.3-2010 does not cover:

• Drywood termites (rare in southern Australia — outside scope)
• Mould (separate scope, not a timber pest)
• Rodents (separate inspection)
• Underground inspection — house stumps below ground level, tree roots, parts of fence posts below grade

If a report is sold to you as covering “everything,” that is wrong by the standard. AS 4349.3 is a defined scope; an honest inspector will tell you what’s in it and what isn’t.

Older Adelaide homes — what it really means

There is no formal “exemption” for older Adelaide homes. What there is — and what many homeowners haven’t been told — is the construction-era reality: much of inner Adelaide was built long before modern termite-management standards.

A home built in 1922 (Norwood villa), 1947 (post-war Prospect bungalow) or 1958 (Mitcham brick-and-tile) almost certainly had no termite management system installed to today’s standards at construction.

This is not a get-out clause. It is the reason AS 3660.2-2017 matters.

What it means in practice:

• Older homes usually have no original termite management system. Whatever protection exists today (if any) was retrofitted later — or doesn’t exist at all.
• The Norwood, Unley, Prospect, Walkerville, Semaphore, Port Adelaide and Gawler character areas sit in this category by default. Heritage construction (suspended timber floors, mature gardens, no slab edge to inspect) is a high-risk termite profile.
• For these homes, AS 3660.2-2017 is the relevant guidance. Part 1 doesn’t apply unless there’s new building work. Part 2 covers inspection, management options if termites are found, and regular inspections no more than 12 months apart.
• If you’re selling, buyers and their conveyancers will often want a written AS 4349.3-2010 timber pest inspection on a heritage property, regardless of “no termites visible.”

If you own an older home in Adelaide and you have never had a termite inspection, you are not non-compliant — you are uninspected. Different problem, different fix.

What a competent inspection includes

AS 3660.2-2017, working with AS 4349.3-2010, sets the scope. A competent Adelaide termite inspection includes the following — every job, regardless of property age.

Subfloor

The single highest-yield zone in pre-1970s Adelaide stock. The inspector examines:

• Bearers, joists and piers — visual + acoustic sounding for hollow timber
• Ant caps over piers — present, intact, undisturbed
• Ventilation — blocked vents = elevated moisture = termite-favourable subfloor
• Moisture levels in timber — checked with a calibrated moisture meter
• Mud tubes on piers, slab edges, internal foundation faces

Subfloors with restricted crawl access are noted explicitly in the report under AS 4349.3 — the inspector does not skip them silently.

Internal timbers

• Skirtings, architraves, door jambs, window reveals — tapped and probed
• Cornices and exposed structural posts
• Wet-area timbers (bathroom, laundry, kitchen) — moisture meter on every timber edge
• Plasterboard surfaces — checked for blistered paint, pin-holes with brown staining, surface deflection

Roof void

• Rafters, ridge beams, hanging beams — visual and tapped
• Valleys, sarking, flashings — moisture-related decay risk
• Insulation — lifted at random points to check the timber underneath
• Heat anomalies — thermal imaging where an active gallery is suspected

External surrounds

• Fascias, eaves, deck framing — accessible at ladder height
• Retaining sleepers within slab proximity
• Garden beds against the slab edge — soil heaped against the slab is the single most common conducive condition in suburban Adelaide
• Weep-hole obstruction — bricks below DPC need air circulation; mulch and pavers covering them is a flag
• Trees and stumps near the house — subterranean termites forage underground, often well away from the nest

Outbuildings within 30 metres

Sheds, carports, granny flats, separate workshops. A termite colony does not respect the property’s main-house boundary. AS 4349.3 includes outbuildings within 30 metres in the standard inspection scope.

Conducive conditions

The inspector documents every site condition that elevates termite risk, even if no active workings are visible:

• Slab-edge soil contact
• Untreated softwood landscaping (sleepers, garden borders)
• Drainage failures and pooling water near the building
• Plumbing leaks (mains, hot water, irrigation)
• Tree stumps within 50 metres
• Mulch and bark layered against the slab

The conducive-conditions list often runs to a page on its own. It is the basis of the inspector’s recommendations for the next 12 months.

What a thermal-only inspection misses

Thermal imaging cameras are useful. They do not see termites. They see temperature anomalies in walls and timbers that indicate possible active galleries — water sources, heat from active foraging, moisture differentials. Used correctly alongside a physical inspection, thermal imaging converts a visual sweep into a structural assessment.

Used as the only inspection method, a thermal camera misses:

• Inactive galleries in dry timber (no thermal signal, plenty of structural damage)
• Termite damage to hidden subfloor timbers (the camera can’t see through the floor)
• Conducive conditions in the soil and external surrounds (no thermal cue)
• Borer activity (lyctus, anobium — not termites, also inside AS 4349.3 scope)
• Timber decay (wet rot — moisture is detectable, but the structural damage from rot needs a physical sounding)

A thermal-only inspection at $99 is not cheap. It is incomplete. AS 3660.2-2017 and AS 4349.3-2010 require a physical inspection of every accessible area, supplemented by — not replaced by — non-invasive technology.

The kit a competent Adelaide inspector carries:

• Thermal imaging camera (Termatrac, FLIR class) — heat signatures
• Moisture meter — moisture-content readings on accessible timbers
• Borescope — into wall cavities and inaccessible voids
• Acoustic sounding tool / probe — hollow-timber confirmation
• Termatrac T3i (radar-based) — movement detection inside walls
• Torch + headlamp — subfloor and roof-void illumination

No single instrument is the inspection. The inspector is.

Which standard applies to your home

A simple decision tree.

• You’re building or extending in 2026. AS 3660.1-2014 governs the system installed at slab stage. The builder’s termite installer issues the durable notice for the meter box. AS 3660.2 takes over from year one onward.
• You bought a 1985 home with an existing barrier. AS 3660.2-2017 guides your regular inspections. The barrier may be original or a later retrofit, and it may not meet current standards. The inspector confirms what’s in place and reports following AS 4349.3.
• You own a 1922 Norwood villa. AS 3660.2-2017 alone. No original barrier was installed. Annual inspection at the recommended 12-month interval. AS 4349.3-2010 governs the report form.
• You’re about to buy a property. AS 4349.3-2010 with the additional pre-purchase scope. The inspection finds what’s there before settlement. See the pre-purchase termite inspection guide.
• You found mud tubes yesterday. Stop disturbing them. AS 3660.2-2017 inspection inside the week — book one at our termite inspection service page. Treatment options follow positive ID. The cost ranges sit in the termite treatment cost guide.

Book a termite inspection in Adelaide

If you’re reading this because you need an inspection rather than a lesson in the standards, that’s exactly what our termite inspection service in Adelaide is for. We inspect to AS 3660.2-2017 and report to AS 4349.3-2010, covering the subfloor, internal timbers, roof void, external surrounds and outbuildings, and you get a written report with photos and a clear recommendation.

The risk looks different across town. Heritage villas with suspended timber floors dominate termite control in the eastern suburbs; sandy coastal blocks change the treatment options in the western suburbs; and post-war slab homes from Marion to Morphett Vale are the core of our southern suburbs termite work. Whichever side of Adelaide you’re on, the inspection standard is the same.

Request a termite inspection quote — tell us the suburb, the age of the house and whether you’ve seen any signs, and we’ll get back to you within 24–48 hours.

What to expect on the day

A standard residential AS 3660.2-2017 inspection in Adelaide looks like this.

1. Arrival and brief. The inspector confirms property scope (storeys, outbuildings, subfloor access, roof-void access), introduces the kit, and asks about any signs the homeowner has noticed.
2. External walk. Slab perimeter, weep-holes, drainage, garden beds, retaining sleepers, trees and stumps within 50 metres.
3. Subfloor. Crawl access where available; visual + sounding on bearers, joists, piers; moisture meter on suspect points; thermal camera on wet zones.
4. Internal sweep. Wet rooms first (bathroom, laundry, kitchen); skirtings, architraves, door jambs, window reveals; moisture meter on every wet-area timber edge; sounding on accessible structural timbers.
5. Roof void. Rafters, ridge beams, hanging beams; insulation lifted at random points; thermal camera on suspect zones.
6. Outbuildings. Sheds, carports, granny flats — same scope as the main building, scaled.
7. Debrief on site. Plain-English summary of findings before the inspector leaves. No surprises in the written report.
8. Written report within 24–48 hours. AS 4349.3-2010 form and content. Severity grading. Photographs. Recommendations.

If you’ve never had a termite inspection, expect 60–90 minutes on a single-storey home with reasonable access. Larger homes, two-storey, or restricted subfloor access can take 2 hours or more.

Licences to check

Pest control licensing in South Australia sits under the Controlled Substances Act 1984 and the Controlled Substances (Pesticides) Regulations 2017, administered by SA Health’s Controlled Substances Licensing. Two licences are relevant:

• Pest Controller’s licence — the business licence. Any business offering pest control for fee or reward needs one.
• Full Pest Management Technician (FPMT) licence — the technician licence for unsupervised work. FPMTs carry a photo ID card showing their endorsements — check it covers termite work.

A Limited Pest Management Technician (LPMT) works under an FPMT’s supervision. SA Health runs an online licence look-up, so you can check any business and technician before booking.

Some operators also belong to industry associations such as AEPMA. Membership is voluntary; the SA Health licence is the legal requirement, so check that first.

Frequency and cost in Adelaide

AS 3660.2-2017 recommends inspections at intervals of not more than 12 months for most properties. Shorter intervals — 6-monthly — are recommended for high-risk sites. High-risk in Adelaide context means:

• Pre-1960 housing stock (Norwood, Unley, Prospect, Walkerville, Semaphore)
• Reactive clay soils with established gardens (Prospect/Sefton Park calcarosol band; Mitcham foothills clay)
• Properties on bushland fringes (Belair, Stirling, Aldgate, Mount Barker)
• Properties under active treatment or monitoring
• A previous infestation, even if treated and cleared

Cost guidance for a standard residential inspection in Adelaide sits at $180–$350. The drivers (size, storeys, subfloor and roof-void access, outbuildings, pre-purchase scope) are explained on the termite inspection service page and broken down further in the termite treatment cost article.

What the inspection won’t tell you

Worth saying explicitly because every inspection question follows from it.

• The inspection is a snapshot — it tells you the building’s status on the day. A clean report does not mean a clean house in 18 months. The 12-month re-inspection is how status stays current.
• The inspection does not include destructive investigation. AS 4349.3 is a non-invasive standard. If a finding requires opening up a wall, lifting a floorboard, or removing cladding, the inspector recommends further investigation — and quotes for it.
• The inspection does not value the property. It does not determine whether to buy, sell or renovate. It tells you what’s there. Decisions are yours.
• The inspection does not certify a barrier. Part 1 systems are documented at construction (including the durable notice). The inspector checks what is in place and whether it appears to be doing its job — they do not re-certify it.

FAQ

How often should I get a termite inspection in Adelaide? AS 3660.2-2017 calls for regular inspections no more than 12 months apart. Higher-risk sites — older homes, reactive clay soils, established gardens, bushland fringes, properties under active treatment — may benefit from 6-monthly intervals.

Which Australian Standard applies to my termite inspection? The inspection methodology is governed by AS 3660.2-2017 (existing buildings) or AS 3660.1-2014 (new building work). The report itself is governed by AS 4349.3-2010. For an older Adelaide home, Part 2 is the relevant part — Part 1 covers new building work.

My home is from the 1920s — does AS 3660 apply? AS 3660.1-2014 (new building work) doesn’t, because your home was built long before it. AS 3660.2-2017 covers termite management in and around existing buildings, and AS 4349.3-2010 covers timber pest inspections. Both are relevant to a 1920s villa.

What’s the difference between AS 3660.1 and AS 3660.2? AS 3660.1-2014 covers termite management for new building work (the system installed at slab stage). AS 3660.2-2017 covers termite management in and around existing buildings (the inspection and retrofit regime for buildings already standing). They are companion parts of the same standard, written for different stages of a building’s life.

Is a thermal-only inspection acceptable under AS 3660.2-2017? No. AS 3660.2-2017 requires a physical inspection of every accessible area (subfloor, internal, roof void, external, outbuildings). Thermal imaging is a supplement to the physical inspection, not a replacement. A thermal-only inspection misses inactive galleries, hidden subfloor damage, conducive conditions, borers and timber decay.

How long does a termite inspection take in Adelaide? 60–90 minutes on a standard single-storey home with reasonable subfloor and roof-void access. Two-storey homes, restricted access, or properties with multiple outbuildings can run 2 hours or more.

What licence does my termite inspector need in SA? In SA, the business needs a Pest Controller’s licence and technicians applying pesticides need a Full or Limited Pest Management Technician licence, under the Controlled Substances (Pesticides) Regulations 2017. Both are issued by SA Health, and you can check them with SA Health’s online licence look-up.

Does AEPMA membership matter? It’s voluntary. Industry associations like AEPMA have their own codes and requirements, but the legal requirement in SA is the SA Health licence — check that first.
