Cyclone Season 2026–27: A Darwin Pre-Season Property Checklist
Cyclone season opens 1 November. The property-side checklist for Darwin and Palmerston — what to clear, trim, fix and check while the weather still lets you.
The Northern Territory cyclone season runs from 1 November to 30 April, and NT Police, Fire and Emergency Services notes that cyclonic events have occurred outside that window as well. The Top End is naturally exposed: on average some two to three cyclones affect the region between November and April each year.
Emergency kits, radios and evacuation plans are well covered by SecureNT and the emergency services, and you should follow their advice on all of it. What follows is the part that falls to the property itself — the maintenance jobs that are straightforward in October and either impossible or expensive once the weather turns.
The window is now. Trades book out through late October, and the first serious storms do not wait for you to be ready.
Start with the yard, because it is the cheapest risk you will ever remove
In a cyclone, the damage to most suburban Darwin houses is not done by the wind directly. It is done by objects the wind picked up. NT emergency services advice is explicit about clearing your property of loose material that could blow about and cause injury or damage in extreme winds.
Walk the block and deal with:
- Unsecured outdoor furniture, pot plants, bins, toys and garden ornaments — and decide now where they will go, because "I'll put it in the shed" is not a plan if the shed is already full
- Offcuts, timber, pavers, sheet metal and star pickets left over from a project
- Trampolines and shade sails. A shade sail left up in a cyclone takes its posts, and sometimes a section of wall, with it. Plan to drop it.
- Loose sheets of roofing or fencing that have already worked free
Trees and vegetation
Emergency services advice is to trim tree tops and branches well clear of the house — and to check with your council first, because many Darwin trees are protected and some work needs permission.
Priorities, in order:
- Anything overhanging the roof. A branch that drops on a roof in high wind takes the roof with it.
- Dead or half-dead limbs. These are the first things to go and the most likely to become projectiles.
- Palm fronds. Dead fronds are heavy, sharp and fly a long way. Get them down.
- Vegetation against the walls and around the condenser units. Clearing it helps airflow now and reduces debris later.
Our guide to cyclone-proofing a Darwin garden goes further into species and planting choices if you are thinking beyond this season. For the work itself, AusMCo's lawn and garden team does pre-season cleanups across Darwin and Palmerston, and green waste removal is the part most people underestimate.
Roof, gutters and stormwater
This is where deferred maintenance turns into an insurance claim.
- Clear the gutters and downpipes. A monsoonal downpour onto a blocked gutter puts water over the fascia and back into the eaves. Dry-season debris is still sitting up there right now. Our gutter cleaning service covers this, and the hidden cost of dirty gutters explains what it actually does to a building.
- Check for loose or lifted roof sheets and flashing. Wind gets under a lifted edge and peels. A handful of screws now is a different conversation from a re-roof.
- Look at the ridge capping and the valleys. Cracked mortar and rusted valley irons are both common on older Darwin builds.
- Test the stormwater. Run a hose into the system and confirm it discharges where it should. See stormwater drainage maintenance for what to look for.
Openings: doors, windows and screens
A failed opening is how wind gets inside a house, and once it is inside the pressure works against the roof from below.
- Check that every window and door latches properly and that the locks engage. A door that only closes if you lean on it will not hold.
- Inspect seals and weatherstripping. After six months of dry-season UV these are often flat or cracked — seal repairs covers the assessment.
- Check security screens and their fixings. A screen hanging on two of four fixings is a projectile.
- If the house has cyclone shutters, operate every one of them now. Do not discover a seized shutter during a warning.
The structural items worth a professional look
Some things are worth having someone competent assess before the season rather than after:
- Carports, patios, pergolas and verandah roofs. These are the most commonly damaged structures on Darwin properties, usually at the post-to-slab or beam-to-post connection. Our carpentry and building maintenance team checks and repairs these.
- Termite-damaged timber. Compromised structural timber and 150 km/h winds are a bad combination. If you are unsure, the warning signs are worth knowing.
- Fences and retaining walls. A leaning fence will not survive, and whichever way it falls is somebody's problem.
- Sheds and garden structures. Check the anchoring, not just the structure.
Documentation — the ten minutes that pays for itself
Before the season starts, walk the property with your phone and photograph everything: each elevation, the roof from ground level, the fences, the outbuildings, the condition of the yard. Note the date.
If you ever make a claim, the argument is almost always about what condition something was in beforehand. Time-stamped pre-season photos end that argument. Landlords and property managers should do this as a matter of course, and keep it with the file.
A realistic order of work
If you cannot do everything, do it in this order:
- Clear the yard of anything loose — free, and removes the most common cause of damage
- Clear the gutters and test the stormwater
- Trim overhanging and dead branches
- Fix anything loose on the roof
- Check every door, window, screen and shutter latches and holds
- Get the carport, patio and any suspect timber assessed
- Photograph the lot
Getting it done
AusMCo does pre-season property preparation across Darwin, Palmerston, Howard Springs, Humpty Doo and the rural area — gutter clearing, garden and green waste cleanups, roof and structure repairs, seals, screens and fencing. For landlords and agencies we can work through a portfolio and report on each property.
