Termites cost Australian homeowners more than $1.5 billion in damage each year. CSIRO estimates that one in three Australian homes will experience a termite encounter during their lifetime. You open a wall cavity during a renovation and find hollowed-out timber. Or your floor starts sagging near the bathroom. You call the insurer expecting a payout, and they decline the claim.
This happens to thousands of Australians each year because standard home insurance policies do not cover termite damage. The insurance industry classifies termite infestation as a maintenance issue, not a sudden or accidental event. That distinction determines whether your insurer pays.
Why Insurers Exclude Termite Damage
Home insurance covers events that are sudden and unforeseen: storms, fires, burst pipes, theft. Termite damage builds over months or years. Insurers treat it the same way they treat rust, mould, and gradual deterioration. The policy wording in most Product Disclosure Statements (PDS) lists pest damage under general exclusions.
AAMI's home building policy states the exclusion in Section 4: damage caused by insects, vermin, or animals. NRMA uses similar language. Allianz excludes damage from "birds, vermin, insects, or animals" across all tiers. RAC in Western Australia excludes "gradual deterioration" and "damage by animals or insects" as separate clauses.
The logic from the insurer's perspective: you can prevent termite damage through regular inspections and chemical barriers. You cannot prevent a hailstorm. Insurance exists for risks you cannot control, not maintenance you choose to skip. Rental property owners should understand property management fees too, since many agents handle pest inspection scheduling.
What Major Insurers Cover and Exclude
Every major Australian home insurer excludes termite and pest damage from standard building and contents policies. The specific wording varies, but the outcome is the same.
| Insurer | Termite Damage Covered? | PDS Exclusion Reference |
|---|---|---|
| NRMA | No | General Exclusion: insects, vermin, animals |
| AAMI | No | Section 4: damage by insects or vermin |
| Allianz | No | General Exclusion: birds, vermin, insects, animals |
| Suncorp/GIO | No | General Exclusion: gradual pest damage |
| RAC (WA) | No | Exclusion: animals or insects |
| Budget Direct | No | General Exclusion: pest or vermin damage |
| QBE | No | General Exclusion: insects and vermin |
No Australian home insurer offers termite damage as a standard inclusion or optional add-on at the time of writing. Some overseas markets (parts of the United States, for example) offer termite bonds or endorsements. The Australian market does not.
The One Exception: Resultant Damage
Some policies cover damage that results from a covered event, even if the underlying cause is excluded. Here is the scenario: termites weaken a structural beam. A storm hits, and the weakened beam collapses, bringing down part of the roof. The storm damage itself is a covered event. Your insurer may pay for the roof repair caused by the storm, but will not pay to replace the termite-damaged beam.
This distinction matters. If termites chew through wiring and cause an electrical fire, the fire damage may be covered. The wiring repair will not be. Read your PDS for the specific "resultant damage" clause. NRMA and Suncorp include language that separates the insured event from the excluded cause.
Filing a resultant damage claim requires you to prove the covered event (storm, fire) was the proximate cause of the loss. Your insurer will send an assessor who will identify the termite damage as the root cause. Expect pushback. Document the covered event with photos, emergency service reports, and independent building assessments.
Disputing a Declined Termite Claim
If your insurer declines a claim that involves termite damage, you have recourse through the Australian Financial Complaints Authority (AFCA). AFCA handles disputes between consumers and insurers at no cost to you. Before lodging with AFCA, file a formal complaint through your insurer's Internal Dispute Resolution (IDR) process. The insurer has 30 calendar days to respond.
If the IDR response is unsatisfactory, lodge with AFCA within two years of the insurer's final decision. AFCA reviews the policy wording, the claim circumstances, and the insurer's conduct. For resultant damage disputes, AFCA has sided with consumers in cases where the insurer failed to distinguish between the excluded cause (termites) and the insured event (fire, storm collapse). Keep every document: the original claim, the insurer's written decline, the IDR correspondence, and all building or pest inspection reports.
A public loss assessor can also strengthen your claim. Loss assessors work for you (not the insurer) and charge a fee or a percentage of the payout. They review the policy wording, gather evidence, and present the claim in the strongest terms. For claims above $20,000, the assessor's fee can be worth the investment.
How Much Termite Damage Costs to Fix
Repair costs depend on how long the colony has been active and which structural elements they've reached. A minor infestation caught within the first few months might cost $2,000 to $5,000 to treat and patch. A major structural compromise can run $50,000 to $100,000 or more.
| Damage Severity | Typical Repair Cost | Timeframe of Infestation |
|---|---|---|
| Minor (cosmetic timber damage) | $2,000 - $5,000 | Under 6 months |
| Moderate (floor or wall framing) | $10,000 - $30,000 | 6 - 18 months |
| Major (structural beams, subfloor) | $30,000 - $80,000 | 18 months - 3 years |
| Severe (full restumping or rebuild) | $80,000 - $150,000+ | 3+ years undetected |
Treatment alone (chemical soil barrier or baiting system) costs $2,000 to $5,000 for an average-sized home. That figure covers eliminating the active colony and installing protection against reinfestation. The repair cost sits on top of that.
Protecting Your Home Without Insurance
Since insurance won't help, prevention is your entire strategy. Australian Standard AS 3660 sets the framework for termite management in new and existing buildings.
Annual termite inspections run $250 to $400 for a standard residential property. A licensed pest inspector checks subfloor areas, roof voids, wall cavities, and the perimeter. They use moisture meters, thermal imaging cameras, and sometimes radar to detect colonies behind walls. The Building Code of Australia recommends annual inspections for all homes in termite-prone areas, which covers most of the continent except Tasmania.
Chemical soil barriers last five to eight years. A licensed technician trenches around the foundation and applies termiticide (bifenthrin or fipronil) to create a treated zone. Cost: $2,000 to $4,000 depending on soil type and house footprint. Reticulation systems allow retreatment without re-trenching.
Baiting systems use in-ground stations around the perimeter. Termites feed on the bait and carry the active ingredient back to the colony. Brands like Sentricon, Exterra, and Nemesis cost $2,500 to $4,500 installed, with annual monitoring fees of $300 to $500. These systems work well for homes where trenching is impractical.
Physical barriers (stainless steel mesh, granite particles, or sheet membranes) go in during construction. Retrofitting them is expensive and disruptive. If you're building new, specify a compliant physical barrier system. Granitgard and Termimesh are the two most common brands in Australia.
Reduce conditions that attract termites. Store firewood away from the house, not against the external wall. Fix leaking taps and downpipes because termites need moisture. Clear garden beds from direct contact with the foundation. Remove tree stumps within five metres of the house. These steps don't eliminate risk, but they remove the easy entry points.
Pre-purchase pest inspections are mandatory common sense when buying a home, even though they're not a legal requirement in most states. A timber pest inspection under AS 4349.3 costs $250 to $400 and identifies active termite activity, old damage, and conditions conducive to infestation. If the report flags issues, negotiate the price down or walk away. Buying a house with existing termite damage and no barrier system will cost you tens of thousands in repairs within five years. Our guide on building vs buying a house covers how to evaluate properties for long-term value.
What to Do If You Find Termites
Do not disturb them. Termites retreat when threatened, and a disturbed colony will relocate to another part of the house. Do not spray insect killer. Do not break open the damaged timber to look inside.
Call a licensed pest controller with termite-specific experience. In Australia, pest controllers must hold a licence issued by their state or territory health department. Check the Australian Environmental Pest Managers Association (AEPMA) directory for accredited operators.
Get two quotes for treatment. Ask each operator to specify the treatment method, the active chemical, the warranty period, and whether annual inspections are included. Reputable operators provide a written report under AS 4349.3 (the timber pest inspection standard) before recommending treatment. Landlords should also review their landlord insurance policy to understand what pest-related costs their cover includes.
After treatment, hire a structural engineer or licensed builder to assess damage. They will determine which timbers need replacement and whether the structural integrity of the building has been compromised. Keep all reports and invoices. If you sell the property later, buyers will ask for termite history.
Some pest control companies offer a damage warranty: if termites return and cause damage within the warranty period, the company pays for repairs up to a set limit ($100,000 to $250,000 is typical). This is the closest thing to termite insurance available in Australia. Read the warranty conditions. Most require you to maintain annual inspections and keep the chemical or baiting system active.
