A termite inspection is one of the most important maintenance investments an Australian homeowner can make. With termites causing an estimated $1.5 billion in damage to Australian properties each year — and most home insurance policies explicitly excluding termite damage — understanding what an inspection costs, what it covers, and how often you need one is essential. This 2026 guide provides real pricing, a breakdown of inspection types, and clear guidance on what to expect.
Termite Inspection Costs at a Glance (2026)
Termite inspection pricing varies by inspection type, property size, and whether thermal imaging is included:
| Inspection Type | Typical Cost Range | Duration |
|---|---|---|
| Standard visual inspection (AS 3660.2) | $250–$450 | 1–2 hours |
| With thermal imaging upgrade | $350–$600 | 1.5–2.5 hours |
| Pre-purchase inspection (AS 4349.3) | $400–$600 | 1.5–3 hours |
| Combined building + pest (AS 4349.0 + AS 4349.3) | $500–$900 | 2–3.5 hours |
| Annual monitoring visit (with existing system) | $150–$300 | 45–90 minutes |
What a Termite Inspection Covers: Complete Scope
A thorough termite inspection under Australian Standard AS 3660.2 covers all accessible areas of the property. Here's what a compliant inspection includes:
Interior of the Property
- All internal rooms: walls, floors, ceilings, architraves, and skirting boards
- Built-in cupboards, wardrobes, and storage areas
- Wet areas: bathrooms, laundries, and kitchens (moisture = termite risk)
- Internal door frames and window frames
Subfloor (if Accessible)
- Floor bearers, joists, and stumps
- Earth-to-timber contact points (a critical risk factor)
- Drainage and moisture levels (moisture meter readings)
- Evidence of mud leads, galleries, or frass
Roof Void (if Accessible)
- Roof rafters, purlins, and strutting beams
- Roof frame connections and fascia
- Evidence of past or active termite activity
Exterior and Garden Areas
- Full perimeter of the building
- Garden timbers: sleepers, edging, garden beds adjacent to the structure
- Timber fences and retaining walls
- Pergolas, decks, and outbuildings
- Tree stumps and dead wood (common termite harbourage)
- Sub-slab expansion joints and weepholes
Written Report
Every compliant inspection results in a written report that includes:
- Date of inspection and inspector's credentials
- Description of areas inspected and any inaccessible areas
- Evidence of termite activity (with photographs)
- Conditions conducive to termite attack
- Moisture meter readings at key locations
- Risk rating for the property
- Recommendations for treatment or monitoring
The Problem with Free Termite Inspections
Free termite inspections are a common marketing tool in the Australian pest control industry. Understanding their limitations protects you from wasted time and potentially misleading assessments.
What "Free" Often Means in Practice
- Limited scope: Free inspections may cover only accessible ground-floor areas — not roof voids, subfloor (if tight access), or all outbuildings.
- Sales focus: The inspector has a commercial interest in finding — or not finding — termites in ways that justify their product offering. A baiting system company may find evidence that justifies a $4,000–$8,000 system where an independent inspector might rate the risk as low.
- Not AS 3660.2 compliant: Many free inspections are not conducted to the Australian Standard. The resulting assessment carries no professional accountability.
- High-pressure sales: Free inspections frequently culminate in on-the-spot treatment quotes. The urgency pressure tactic is common and effective.
How Often Do You Need a Termite Inspection?
Australian Standard AS 3660.1 (termite management in new buildings) and industry guidance from the AEPMA both specify inspection frequency based on risk level:
Standard Frequency: Annual
Annual inspection is the minimum recommended frequency for all residential properties in Australia. Termite activity can establish and cause significant structural damage within 3–6 months in high-activity conditions. An annual inspection catches activity before it becomes a structural problem.
High-Risk Properties: 6-Monthly
Six-monthly inspections are recommended for:
- Properties in high-activity termite zones (coastal and tropical Queensland, Northern Territory, northern New South Wales, WA Kimberley and coastal zones)
- Properties adjacent to bushland, native vegetation, or large trees
- Properties with known conducive conditions (earth-to-timber contact, drainage issues, previous termite history)
- Properties with ageing or partial chemical barriers
Annual Monitoring Cost
If you have an existing baiting system or chemical barrier, annual monitoring visits typically cost $150–$300. This is significantly less than a full inspection and is conducted by the company that installed and guarantees your system. However, it should not replace periodic independent inspections.
Standard Visual Inspection vs. Thermal Imaging: Which Do You Need?
Thermal imaging is the most meaningful upgrade available for termite inspections. Here's a clear comparison:
Standard Visual Inspection ($250–$450)
An experienced inspector with a moisture meter and physical probing tools can detect:
- Visible mud leads, galleries, and frass
- Damaged and hollow-sounding timber
- Conducive conditions (moisture, earth contact, cracks)
- Visible evidence in accessible subfloor and roof void
With Thermal Imaging ($350–$600)
A thermal camera detects heat differentials — active termite colonies generate heat, and moisture trapped in walls shows as distinct thermal signatures. Thermal imaging adds detection capability for:
- Active colonies within wall cavities and behind linings
- Moisture accumulation indicating hidden leaks or termite activity
- Activity in areas with limited physical access
Thermal imaging does not eliminate the need for a standard visual inspection — it supplements it. The camera is not foolproof: an inactive colony at the time of inspection won't generate heat. Thermal imaging is most valuable in:
- High-risk zones where hidden activity is a realistic concern
- Older properties with extensive wall linings
- Pre-purchase inspections where stakes are highest
For pre-purchase inspections specifically, see our dedicated pre-purchase pest inspection cost guide.
What Happens After the Inspection
The inspection report drives one of three outcomes:
No Activity Found — Low Risk
You receive a clean report. The recommendation will be annual re-inspection and potentially a review of any conducive conditions. No treatment is required.
Conducive Conditions Found — Elevated Risk
No active termites, but conditions that invite attack are present. The inspector will recommend remediation (improve drainage, remove earth-to-timber contact, address moisture) and potentially a preventative barrier. Re-inspection in 6–12 months.
Active Activity Found
This triggers an immediate treatment recommendation. Do not disturb the activity — termites detect disturbance and will relocate the colony, making treatment harder. Get 2–3 independent quotes. See our termite treatment cost guide for full pricing on chemical barriers, baiting systems, and localised treatments.

Termite Risk by State: Where Inspections Matter Most
Termite risk in Australia is not uniform. The CSIRO's termite risk map divides Australia into four hazard zones. In practical terms:
High-Risk States and Territories
- Queensland: The highest-risk state. Tropical and subtropical climate supports year-round termite activity. Coastal and inland Queensland are both high-risk. Find inspectors via our QLD directory.
- Northern Territory: Extreme risk. All structures require comprehensive termite management.
- Western Australia (coastal): Moderate to high risk across the southwest. Find inspectors via our WA directory.
- New South Wales (northern and coastal): High risk, particularly in the Hunter, Central Coast, and Northern Rivers regions. Find inspectors via our NSW directory.
Moderate-Risk States
Victoria, South Australia, and Tasmania have lower termite pressure overall but are not immune — particularly in areas with wet conditions, proximity to bushland, or older housing stock. Annual inspections remain the recommended minimum.
Frequently Asked Questions
How much does a termite inspection cost in Australia?
A standard visual termite inspection costs $250–$450 in 2026. With thermal imaging, expect $350–$600. Pre-purchase inspections to AS 4349.3 run $400–$600. Combined building and pest inspections cost $500–$900. Annual monitoring visits with an existing system cost $150–$300.
How long does a termite inspection take?
Duration depends on property size and complexity. A standard inspection on a typical 3-bedroom house takes 1–2 hours. Larger properties, those with full subfloor access, or properties with roof void access may take 2–3 hours. Combined building and pest inspections typically take 2–3.5 hours.
How often should I get a termite inspection?
Annual inspection is the minimum recommended frequency for all Australian properties. High-risk properties — those in tropical or coastal zones, adjacent to bushland, with previous termite history, or with conducive conditions — should be inspected every 6 months.
What's included in a termite inspection?
A compliant inspection covers all accessible areas: subfloor, roof void, interior (all rooms, wet areas, built-ins), exterior perimeter, garden timbers, fences, retaining walls, pergolas, and outbuildings. The inspector uses moisture meters and produces a written report with findings, moisture readings, and recommendations.
Are free termite inspections reliable?
Free inspections offered as a marketing tool are typically limited in scope, not AS 3660.2 compliant, and conducted by staff with a commercial interest in selling treatments. They are not a substitute for a fee-for-service inspection by an independent, licensed inspector.
Is thermal imaging worth the extra cost for a termite inspection?
For most standard annual inspections on low-to-moderate-risk properties, standard visual inspection is sufficient. Thermal imaging ($100–$200 extra) adds meaningful value for pre-purchase inspections, high-risk zones, older properties with limited access, or where previous termite activity is documented.
What happens if my termite inspection finds active termites?
Do not disturb the activity — termites will relocate the colony when disturbed, making treatment harder. Get 2–3 independent treatment quotes. Treatment options include chemical barriers ($2,000–$6,000+), baiting systems ($3,000–$8,000+), and localised treatments depending on the extent of activity.
Does home insurance cover termite damage?
No. Australian home insurance policies universally exclude termite damage, classifying it as gradual deterioration rather than sudden damage. This makes regular inspections — and where warranted, active treatment systems — essential owner-funded protection.
Which states have the highest termite risk in Australia?
Queensland and the Northern Territory have the highest risk. Coastal Western Australia, northern New South Wales, and parts of Victoria and South Australia are moderate to high risk. The CSIRO termite hazard map divides Australia into four zones; ask your inspector to rate your property's specific risk.
Can I inspect for termites myself?
You can check for obvious signs — mud leads along foundations, hollow-sounding timber, damaged wood near moisture sources — but self-inspection does not replace a professional assessment. Termites operate inside wall cavities, subfloor voids, and roof spaces that require trained eyes, proper equipment, and a written AS 3660.2 compliant report.
