Part of the 2025–26 Australian region cyclone season

Tropical Cyclone Koji was a short-lived, broad tropical cyclone that affected Northern Queensland, Australia during January 2026. The seventh named storm of the 2025–26 Australian region cyclone season, Koji originated from a tropical low-pressure area in the north Coral Sea. On 7 January, the disturbance was designated as Tropical Low 12U by the Bureau of Meteorology (BoM) while moving southward. Three days later, the low intensified into a category 2 tropical cyclone on the Australian scale and was assigned the name Koji. Shortly after, Koji began quickly began to weaken and was downgraded to a tropical low the following day. Koji then crossed the northern coast of Queensland between Ayr and Bowen.

Despite falling below tropical cyclone strength prior to landfall, remnant moisture from Koji generated thunderstorms that produced rainfall up to 700 millimetres (28 in) in portions of Queensland, resulting in severe flash flooding. Energy companies reported that 23,000 homes were left without power at the height of the storm. Damage was the most severe in the town of Clermont, where 71 homes were inundated. Following the storm, disaster funds and donations were made to communities affected. The Premier of Queensland reported that over 50,000 cattle had been lost during the storm. One resident sustained an economic loss of AU$200,000 (US$142,000) from Koji. Despite the severity of the damage, no deaths were reported.
