Termites are a serious threat to Australian homes. According to the CSIRO, roughly one in three Australian homes will experience a termite encounter during their lifetime. In Victoria, termites are less prevalent than in tropical states, but they are very much present — particularly in older suburbs with established gardens and in regional areas. A pest inspection before buying can save you from inheriting a very expensive problem.
When do you need a pest inspection?
A pest inspection is recommended for any property with a timber structure— which includes most Victorian houses, particularly those built before the 1990s. Modern brick veneer homes still have timber framing, roof trusses, and floor joists that are vulnerable to termite damage.
Apartments and units in concrete buildings are generally lower risk, though ground-floor units and buildings with timber-framed balconies or subfloors can still be affected.
If you're buying at auction, you should arrange the pest inspection before auction day, since there is no cooling-off period after the hammer falls.
What does a pest inspection cover?
A standard timber pest inspection (conducted in accordance with Australian Standard AS 4349.3) covers:
- Subterranean termites: The most destructive pest in Australia. Inspectors look for mud tubes, damaged timber, and signs of live activity.
- Drywood termites: Less common in Victoria but still possible, especially in imported timbers.
- Borers: Wood-boring beetles that create small holes in timber. They are more common than termites in Victoria and can weaken structural timbers over time.
- Wood decay (fungal rot): Caused by moisture and poor ventilation, particularly in subfloor areas.
The inspector will examine accessible timbers throughout the property, including the subfloor (if accessible), roof void, interior walls (tapping for hollow-sounding timber), exterior cladding, fences, retaining walls, and garden structures.
What does it cost?
A standalone pest inspection in Victoria typically costs between $250 and $400. Many buyers combine it with a building inspection for a combined price of $500 to $800. The cost varies by property size and location.
Understanding the report
Pest inspection reports use specific terminology:
- “Evidence of live termite activity”— This is the most serious finding. It means termites are actively feeding on the property. Treatment is urgent and damage assessment is needed.
- “Evidence of previous termite activity”— Termites were present at some point but are no longer active. The key questions are: how much damage was done, was it treated, and is there ongoing protection?
- “Conditions conducive to timber pest attack”— This means the property has features that attract termites, such as stored timber against the house, poor drainage, or lack of ventilation in the subfloor. These are warnings, not infestations.
What to do if the inspection finds problems
If the inspection reveals active termite damage or significant previous damage, you have several options. If you included a subject-to-pest-inspection clause in your contract, you can use it to renegotiate the price, request treatment at the vendor's expense, or walk away from the contract with your deposit returned.
Termite treatment costs vary widely. A chemical barrier treatment for a standard home might cost $2,000 to $5,000. A full baiting system can cost $3,000 to $6,000 to install, with annual monitoring of $500 to $1,000. Repairing structural damage from termites can run into tens of thousands of dollars.
