Tropical Cyclone Fina struck the Northern Territory of Australia towards the end of November 2025, bringing destructive winds, torrential rain, and flooding. It formed on 19 November in the Arafura Sea and quickly intensified, impacting the Tiwi Islands and Darwin as a Category 3 cyclone. Law enforcement issued a broad alert as residents prepared for potential flash floods and power outages. The storm affected roughly 19,000 households, felled trees, and dumped over 150 mm of rain elsewhere – but most remarkably, there were few severe injuries.
Cyclone Fina developed over the Arafura Sea before moving toward Australia’s Top End region.
The system intensified into a Category 3 severe tropical cyclone, bringing destructive winds and heavy rain.
Key affected areas included the Tiwi Islands, Cobourg Peninsula, and coastal regions near Darwin.
The cyclone produced widespread torrential rainfall, causing flash-flood risks across northern communities.
Sustained winds reached around 120 km/h, with stronger damaging gusts.
The storm disrupted transport, electricity supply, and emergency operations.
Authorities issued multiple alerts urging residents to secure their property and follow safety plans.
No fatalities were reported, but infrastructure damage and service interruptions were significant.
The destructive effect of Cyclone Fina in Northern Australia shows how this area is susceptible to extreme weather in tropical conditions. There was extensive destruction, though emergency management and community preparedness minimised the consequences. With hindsight finally setting in, the event strengthens the need to be resilient or be alert and invest in disaster-ready infrastructures as a means of safeguarding lives and livelihoods.
