The most important choice in a pre-purchase inspection is made before anyone opens a manhole. It is the choice of who you hire. Australia does not have a single, national licence that means “this person may write an AS 4349.1 report”. What you get instead is a patchwork of builder licences, pest licences, association memberships, insurance certificates and reputations, some of them earned and some of them rented from a franchise logo.
This is a buyer’s guide to that patchwork. It is also a guide for owners who want a condition report, and for inspectors who are tired of being compared only on price and speed. It is not a directory, and it is not legal advice about who is allowed to trade in your state.
What you are actually buying
You are buying a person’s time on site, a method, and a written record that you will use to decide whether to proceed with a purchase. The product is the report. The quality of the product is the quality of the looking and the honesty of the limitations.
A competent inspector will take longer on a high-set timber house than on a single-storey slab. They will refuse a roof that is unsafe. They will write “not inspected” rather than “appears serviceable” when they could not see the element. They will carry professional indemnity insurance that responds to pre-purchase work. They will not have a side arrangement with the selling agent that depends on reports coming back quiet.
If that sounds obvious, look at the market. Same-day reports for less than the cost of a plumber’s call-out still circulate in every capital. They are written by people who were on site for forty minutes and by software that can generate a hundred-page PDF from a short set of taps. Length is not quality. Time on site is a better proxy, and so is a refusal to inspect from the kerb.
Licences, and the states that actually have them
Queensland
Queensland is the jurisdiction where “are they licensed?” is a fair first question. The QBCC licenses people who carry out and supervise building work, and it also has licence classes that buyers and conveyancers treat as the relevant ticket for inspection work, including pest management licences for the timber-pest half of a combined job. A Queensland buyer should ask for the licence number, look it up, and check that it matches the person who will attend, not only the company on the invoice.
QBCC licensing does not mean the report will be good. It means there is a regulator with a register, a complaints path, and a public record of some disciplinary history. That is already more than several other states offer.
New South Wales
NSW does not issue a neat “building inspector” licence. Many inspectors are licensed builders, or former builders, or people who have come through a trade and an insurance broker. Fair Trading regulates building work and, in a different way, the conduct of people who sell services to consumers. Professional indemnity insurers, industry associations and the courts do a lot of the practical gating.
A NSW buyer who asks “what’s your licence number?” may be given a builder licence, a contractor licence, or a speech about how inspections are not building work. Press the question. Ask what qualification and what insurance sit behind the report. Ask how long the person has been writing pre-purchase reports, which is a different career from building extensions. AS 4349.1 explained is the method they should be using. A builder licence is not that method by itself.
Victoria, Western Australia and the rest
Victoria has registered builders and a domestic building regime; it does not hand every pre-purchase inspector a unique ticket. Western Australia has builder registration and a separate, serious pest-licensing environment. South Australia, Tasmania, the ACT and the Northern Territory each have their own builder and pest arrangements. In the Territory and in northern WA, a pest qualification is not a luxury.
The practical rule across all of them: ask for the specific licence or registration the person holds, the name of the regulator, and a certificate of currency for insurance. Then verify. Do not accept a Facebook badge.
Pest is a different ticket
A building inspector who “has a look for termites” is not automatically a timber pest inspector. AS 4349.3 is a different standard. In several states the chemical and inspection work is licensed separately. Combined building-and-pest firms can be excellent. They can also be a building inspector with a torch and a logo. Ask who is writing the pest report and what licence that person holds.
Insurance: the part buyers forget to ask for
Two policies matter.
Professional indemnity responds when someone says the report was negligent — a missed defect, a misleading limitation, a report that went beyond competence. You want a certificate of currency, the activity description (pre-purchase residential inspection, not “general consulting”), the limit, the excess, and whether the policy is claims-made. Claims-made policies stop covering past work when the inspector stops paying the premium, which is why run-off cover matters if you might need the report in three years.
Public liability responds when the inspector damages the house or injures someone on site. It is the policy that makes a vendor less nervous about a stranger in the roof space. It is not a substitute for PI.
A person who will not show insurance is not cheap. They are uninsured. If the report is wrong, you are in a fight with an individual and a company that may have no assets. Missed defects and an inspector’s duty of care is the legal aftertaste of that fight. The cheaper step is to ask for the certificate now.
Association memberships — Master Builders, HIA, the various inspector associations — are signals, not cover. Some associations require insurance and a complaints process. Some sell a logo. Check which you are looking at.
Red flags before the inspection
The same-day cheap report. A one-storey slab house can be done in a morning. A two-storey weatherboard with a low subfloor and a tiled roof cannot, not if the report is honest. If the fee is a fraction of the local market and the turnaround is “PDF by 4pm”, assume the software is doing the looking.
The vendor-appointed inspector. In some campaigns the vendor has already commissioned a report and attached it to the contract. That document can be useful. It is not your report. You do not know the brief, the access, or whether the inspector expects further work from the agent. Commission your own, or at least have yours reattend.
The agent’s regular. Selling agents keep lists. Some lists are competent people who return calls. Some lists are people who understand that a harsh report ends the referral. You can still use someone from the list. You should also search the name without the agency’s introduction, read a sample, and say out loud, in the email, that you are the client and the report is not to be discussed with the agent before it is discussed with you.
No PI insurance. See above. This is not a paperwork quibble.
Refusal to inspect the roof or the subfloor as a matter of policy. Safety refusals are legitimate. A policy of never leaving the ground floor is not a safety system. It is a business model. An inspector who will not enter a safe, accessible subfloor is skipping the part of an Australian house that tells the truth.
No sample report, or a sample that could be any house. Ask for a redacted report on a similar construction type. You are looking for sentences that could only have been written on site.
Pressure to book the pest with a related chemical company, with a discount if you treat. Combined businesses exist. The conflict should be disclosed. A report that ends in a quote for baiting is a sales document until proven otherwise.
A report written by someone who did not attend. Franchise and call-centre models sometimes separate the person on site from the person who signs. Ask who attends, who writes, and who is named as the inspector.
How to read a sample report
You do not need to be a builder. You need to see whether the document was made by a person who looked.
- Does the construction description match a real house, including decade and roof type?
- Are limitations specific? “Stored goods in garage” is real. “Some areas inaccessible” is fog.
- Do photographs have captions that repeat the finding, not just “photo 14”?
- Is “fair condition” sitting on top of actual observations, or is it doing all the work?
- Does the inspector distinguish major defects, minor defects, safety hazards and further investigation?
- Is there a weather note and a statement of who the client was?
- If it is a combined report, is the pest section written to AS 4349.3, or is it a paragraph at the end of the building notes?
How to brief a building inspector is the companion piece: once you have chosen someone, tell them the construction type, the clause deadline, and the rooms the agent has promised to open. A good inspector still writes a better report when the brief is clear.
Conflicts of interest, said plainly
The selling agent wants the contract to hold. The vendor wants the highest price. The buyer wants to know what is wrong. The inspector is paid by one of those people and works inside a culture created by the other two.
The clean arrangement is that you engage the inspector, you pay the inspector, the inspector addresses the report to you, and the agent’s role is to provide access. Anything else needs a reason.
Vendor-paid reports can be done well, particularly in commercial or volume sales where a serious firm is staking a reputation. In a suburban campaign they are often a marketing attachment. Read them as a starting point.
Inspectors who also do the remediation — the same firm that finds the termites and sells the baiting, or finds the leak and quotes the reroof — can be competent. They cannot be assumed to be disinterested. Get the report. Get a second price for the work.
Referral fees from inspectors to agents, or from agents to inspectors, are the arrangement nobody writes on the listing. If you cannot get a straight answer about how the inspector arrived on the agent’s list, choose someone who did not.
State-by-state practicalities when you are short of time
NSW and VIC auction markets. Inspect before you bid. Choose someone who will attend at short notice without dropping the method. If they cannot get into the roof, they should say so in a pre-auction email, not after you are the owner.
QLD combined building and pest. Check both licence classes. High-set houses take time. Do not accept a ground-floor-only visit on a Queenslander.
WA and NT. Treat pest competence as mandatory. Ask about termite barriers, not only about cracks.
SA and TAS. Ask whether the inspector is comfortable with damp, salt attack and older timber. A national franchise script written around Sydney brick veneer will under-describe a sandstone cottage or a Hobart weatherboard.
ACT. The inspector needs to be available before auction and willing to put limitations in writing the same day.
A worked phone call
You are buying a 1970s brick veneer in the western suburbs of Sydney. You ring two inspectors.
The first can do tomorrow, $299, PDF by evening, “we cover everything”. They cannot say whether they will enter the roof space. They are “covered by the company’s insurance”. They were recommended by the listing agent, who would like a copy of the report.
The second can do Thursday, which is still inside your clause. The fee is higher. They ask about access to the subfloor, the dog, and whether the house is on reactive clay. They will send a sample report and a PI certificate. They will not discuss the findings with the agent before they discuss them with you. They will not inspect the roof if it is wet.
The first inspector is cheaper. The second inspector is the one you can use when the report says the shower needs a plumber and you have two days to decide. Price is information. It is not the brief.
An inspector who will not show insurance, will not enter a safe roof space, or cannot explain who they work for is already writing the limitations page. You just have not received it yet.
Checklist before you pay a deposit on the inspection
- Name of the person who will attend, not only the brand.
- Licence or registration number, and the register you can search.
- Professional indemnity certificate of currency, activity description, and public liability.
- Written agreement that cites AS 4349.1, and AS 4349.3 if pest is included.
- A sample report on similar construction.
- A clear statement that you are the client.
- Time on site appropriate to the house, and a plan for roof and subfloor.
- No obligation to use the same firm for repairs or treatment.
- A timetable that matches the inspection clause, not the agent’s preferred auction week.
Choosing an inspector is a procurement decision with a short deadline and a long tail. The house will still be there on Thursday. A report that cannot be stood behind will be there a lot longer.
