of the Territory’s 499 road closures and restrictions in 2023 began in the Nov–Mar wet season. The disruption isn’t random — it arrives on a schedule.

Traffic activity by region
Total daily vehicle volume across counted roads, 2023
In plain terms: Darwin’s roads carry far more traffic than every other region combined. Elsewhere, volumes are low — so “traffic” as a daily problem is really a Darwin phenomenon.

In plain terms: one big bubble over Darwin, small ones everywhere else — the map makes the imbalance obvious at a glance.
Who it’s for
What this means for you
The same finding, read five ways
Travellers & grey nomads
Driving the Territory Nov–Mar? These roads have historically flooded and stayed cut for days. Time your trip or pick an alternate route before you set off.
Remote community residents
If your access road is one of the long-affected ones, the pattern is your early warning — stock up on essentials and medical supplies before the wet closes it in.
Councils & road authorities
Closures cluster predictably on the same roads each wet. Pre-position drainage and sealing budget on the worst offenders before December, not after.
Emergency services & police
Wet-season cut-offs and high-volume corridors are where rescues, diversions and crash risk concentrate. Pre-stage crews by season, not by surprise.
Freight & tourism operators
Supply runs and tours can route around the predictable cut-off windows — protecting delivery schedules and bookings a mid-wet closure would wreck.
The argument: Congestion is confined to Darwin; everywhere else the network isn’t busy but is seasonally fragile. Because closures cluster predictably in the Nov–Mar wet, access risk is forecastable — councils can pre-position works and travellers can time trips. The NT’s road challenge is planning for a recurring event, not managing daily jams.
