In South-East Queensland, termites don't really have a dormant season — the warm, humid climate keeps colonies active year-round. What does change through the year is how visible that activity becomes: swarms and fresh workings show up more often after warm, wet weather, which on the Gold Coast means spring through the storm season is when the evidence tends to surface. But the more useful pattern from our own inspections isn't about the calendar at all. It's about location. Termites attack from the yard before they reach the house — and the yard is where we find the first activity, not the building itself.

Is there really a termite "season" here?

Not in the way people from cooler climates expect. There is no winter shutdown. What genuinely shifts seasonally is alate activity — the winged reproductive termites that swarm to start new colonies, typically after rain in the warmer months — and how easily conducive conditions like damp soil and saturated garden beds develop. Heavy summer and storm-season rain keeps the ground around a house wet for longer, which is exactly the condition subterranean termites seek out. That's a difference in visibility and opportunity, not a difference in whether termites are active. A property can develop termite damage in any month of the year, and a clear result on inspection day is a snapshot of that day — not a guarantee for the months that follow.

The pattern our own inspections show: it starts in the yard

Across 50 of our own combined building and pest inspections — houses, units, apartments and townhouses across the Gold Coast, Brisbane fringe and Northern NSW — confirmed termite activity or damage appeared in 12 properties, and 11 of those 12 were standalone houses. Just one was a strata property. Within that sample of houses, the pattern was consistent: activity showed up first outside the building, not inside it. A tree stump left in the yard of one established two-storey home carried active termites, with damage tracking into a structural beam and the floor system. A rear boundary fence on another property showed active workings and mudding. A third case turned up confirmed damage in an older home. In every one of these, the property was an established house — in the roughly 18 to 45-year range — not a recent build.

That's the honest takeaway: a tree stump, an old fence line or a stack of garden timber sitting near the house is a genuine termite magnet, and it's usually where activity is found first — well before it reaches the building. Checking your own perimeter, not just the walls of the house, is the non-obvious habit worth building.

What to actually check in the yard

A visual, non-invasive timber pest inspection to AS 4349.3 covers the reasonably accessible areas of the site as well as the building, and these are the conducive conditions we're specifically looking for at ground level:

  • Tree stumps, old tree roots or garden timber left in the ground near the house
  • Fence posts, retaining walls and timber garden edging in contact with soil close to the building
  • Mulch, garden beds or paving built up over the slab edge or against external walls
  • Stored firewood, timber offcuts or formwork resting on the ground under or near the house
  • Standing water or persistently damp soil after rain, close to the foundation

None of these on its own means a property has termites. They're risk factors — conducive conditions, in the language of the Standard — and most established Gold Coast properties will show at least one. What matters is whether they're identified and addressed, because they're the conditions activity tends to develop in first.

Age matters more than the season does

The clearer signal in our own data isn't the month of the year — it's the age and type of the property. Older, established standalone houses account for 11 of the 12 confirmed cases in our sample; just one was a strata property. That single case is a reminder that a unit or townhouse isn't automatically exempt — but the odds, on our own numbers, are noticeably lower than for an older house with yard-level timber, fencing or garden features close to the walls, and that's the property type worth treating with the most caution.

Ground-floor and lower-level units carry their own version of this risk through soil contact at balcony and courtyard level — see our guide to why ground-floor units face higher termite risk than you'd think for how that plays out in strata property.

What this means if you're buying or already own

For a buyer, the practical point is that a pre-purchase timber pest inspection is a condition report for that day, not a permanent clearance — particularly on an established house with garden timber, fencing or stumps near the building. For an owner, it's the case for an annual re-inspection rather than waiting until a swarm or visible damage forces the issue. AS 4349.3 recommends at least yearly timber pest inspections in high-risk climates, and South-East Queensland is squarely one of them.
