AS 4349.3 timber pest inspection reports: what they must contain

AS 4349.3 is the Australian Standard for timber pest inspections of buildings, and it is the standard a pre-purchase timber pest report is written to. Its scope is subterranean and dampwood termites, wood-boring insects and wood decay fungi. Drywood termites are noted as outside that scope — a point worth stating plainly to the client rather than leaving it buried in the limitations.

The inspection it describes is visual and non-invasive. You report what could be seen from the accessible areas at the time of the inspection, and nothing else. That single constraint shapes the whole document: almost everything the standard asks for beyond the findings themselves exists to make the boundary of what you saw legible to somebody reading the report months or years later.

This guide describes the categories of information a report has to cover so you can build a template around them. It does not reproduce the standard. AS 4349.3 is a copyrighted work sold by Standards Australia and the current edition is the authoritative source. This is general information, not legal advice.

Before any findings, an AS 4349.3 report has to establish who inspected, for whom, where and when. That means the inspector's name, credentials and licence details; the client's identity; an unambiguous identification of the property inspected; the date of the inspection; and a reference to the pre-engagement agreement the client signed.

The licence detail is not administrative padding. A timber pest report is a professional opinion, and its weight depends on the inspector being licensed to give it. Record the licence number and class as they stood on the day of the inspection, not as they stand when the report is later reprinted — licences expire and endorsements change, and a report reprinted two years on with a stale licence block is worse than no licence block at all.

The pre-engagement agreement reference is the hinge between the two documents. The agreement fixed the scope, the access and the exclusions; the findings only make sense measured against that scope. A report that does not point back to its agreement is a report whose limits nobody can verify.

AS 4349.3 findings fall into four categories, and a good report addresses all four explicitly — including with a clear negative where nothing was found.

Conditions conducive to attack are the findings category clients undervalue and operators under-write. A property with no live activity and four conducive conditions is a property that will have activity — the report is describing a trajectory, not just a moment.

Record each condition with its location, why it matters, and what would fix it. A line reading that the subfloor is damp is a compliance entry; a line reading that the subfloor under the rear bedroom holds moisture because the downpipe discharges against the footing, and that redirecting it would remove the condition, is advice a client can act on. It is also, straightforwardly, the section that generates the most follow-on work.

Treat a negative as a finding. A category left silent reads, later, as a category never inspected — and the reader making that inference will be doing it in a dispute.

The list of inaccessible and obstructed areas is the single most litigated part of a pre-purchase timber pest report. AS 4349.3 requires the report to state the areas that could not be inspected and to recommend what would be needed to gain access, because a buyer who later finds damage in an unreported area will ask, first, whether the report told them that area was never looked at.

Generic boilerplate does not survive that question. A sentence saying some areas were inaccessible names nothing and warns nobody. Good practice is specific and physical: the subfloor was accessible to the northern bay only, the remainder having insufficient crawl clearance; the roof void above the rear extension was not accessed as there is no manhole; the ensuite wall cavity is tiled and was not opened; stored goods along the southern garage wall prevented inspection of that wall.

Pair each entry with what access would take and what the client should do about it — remove the stored goods and arrange a re-inspection, install a manhole to the rear roof void. That turns the list from a disclaimer into a recommendation, which is more useful to the client and considerably more defensible for you.

Photograph the obstructions. A photograph of a garage wall stacked to the ceiling settles an argument that a sentence will not.

Every significant finding should carry a photograph, a risk rating and a recommendation with a stated urgency. The photographs are the report's evidence base, the risk rating is the summary judgement the client is paying for, and the recommendation with its urgency is the only part that actually gets acted on.

Urgency has to be concrete. Recommending further investigation is not a timeframe. Distinguish what needs attention before settlement, what needs attention within weeks, and what is a maintenance item for the coming year — a buyer with three days to make a decision needs to know which of your findings belong in that decision and which do not.

Keep photographs beside the findings they support rather than in an appendix nobody opens. A finding without an image is a finding the client can honestly say they did not understand.

An AS 4349.3 report has to state when the next inspection should be carried out and has to be clear that the inspection was visual only. The interval is a professional judgement about that particular property — its construction, its conducive conditions and the local termite pressure — not a default number stamped on every report.

The limitation statements do real work, and they are the part most often reduced to unread fine print. They tell the reader that the inspection was non-invasive, that it reports the situation at the date and time of inspection only, and that it cannot speak to concealed areas. That is honest, and it is also the ground on which the report is defended. Write them so a client will actually read them, and carry the point on the front page rather than burying it on page nine.

Where the interval is short because the property is high risk, give the reason in the same sentence. An interval with a reason attached is far more likely to be honoured — and the reason is already sitting in your conducive conditions section.

Reports that hold up under challenge tend to share the same handful of traits, and none of them are about the quality of the inspection itself.

Nothing here is legal advice. Timber pest inspection licensing differs by state and is still changing in some of them — New South Wales, for instance, has been phasing in a separate timber pest technician licence. Confirm what you need with your state regulator.
