Queensland Floods 2026: Heavy Rainfall and Ex-Cyclone Koji Devastation

Overview of Queensland's 2026 Flood Crisis

Queensland, Australia's sunshine state, has been gripped by one of its most severe flooding events in recent years throughout early 2026. Triggered by a persistent monsoon trough in late December 2025 and exacerbated by ex-Tropical Cyclone Koji in mid-January, the state has experienced torrential downpours leading to widespread riverine and flash flooding. Areas from the Gulf Country in the northwest to central regions around Rockhampton have been hardest hit, with floodwaters lingering due to flat inland topography and saturated soils. 120 117

The crisis began with an active monsoon delivering over a year's worth of rain in days to some spots, followed by Koji's landfall near Ayr and Bowen on January 11. This Category 2 system dumped up to 600mm of rain in 48 hours across key catchments, swelling rivers like the Flinders, Georgina, Isaac, and Fitzroy to major flood levels. As of January 27, flash flooding continues, notably in Far North Queensland's Einasleigh where the Copperfield Dam spilled dramatically. 118

Timeline of the Flooding Events

The sequence unfolded gradually but intensified rapidly. From December 28, 2025, a monsoon trough brought prolonged heavy rain to northwest Queensland, causing initial major flooding on the Flinders and Georgina rivers by early January. By January 5, stock losses were mounting, with producers reporting thousands of cattle missing. 106

• January 9-10: Tropical low develops off coast, warnings issued for flash flooding.
• January 11: Koji crosses coast south of Townsville, downgrades but rainbands persist.
• January 12: Peak impacts in central QLD, Clermont sees heaviest rain since 1916; flash flood emergencies declared. 117
• January 19-20: Fitzroy River peaks at Rockhampton, impacting 280 properties.
• January 27: Overnight 250mm rain causes Copperfield Dam to overtop by 6m, emergency evacuation of Einasleigh. 120

This timeline highlights how slow-moving systems amplified risks, with flood peaks lagging rainfall by days or weeks in slow-draining basins.

Ex-Tropical Cyclone Koji: The Catalyst

🌪️ Ex-Tropical Cyclone Koji, the first named system of the 2026 season, formed from a tropical low and intensified before landfall. With sustained winds of 100 km/h and gusts to 140 km/h, it crossed near Ayr/Bowen around 10:00 AEST on January 11. Though downgraded quickly, its monsoonal rainband tracked inland, delivering extreme precipitation: over 300mm in 6 hours and 600mm in 48 hours in the Fitzroy, Isaac, and Connors basins. 117

The Bureau of Meteorology (BoM) forecasted isolated 340mm falls in 24 hours post-landfall, saturating catchments already primed by prior rains. Koji's remnants dissipated inland within 48 hours, but secondary effects like thunderstorms prolonged the deluge. 118

Hardest-Hit Regions and Latest Developments

North and central Queensland bear the brunt. In the Gulf Country and outback (e.g., Normanton, Cloncurry), roads severed and towns isolated. Central areas like Clermont faced flash floods isolating properties for weeks; Eungella near Mackay may remain cut off for months due to landslips after 700mm in 48 hours. 9

Latest: On January 27, Einasleigh (Etheridge Shire) saw rapid Copperfield River rise after 250mm overnight rain spilled the dam by over 6m. Six homes flooded, including the Einasleigh Hotel; residents like Tayla Wellby described watching furniture float away, calling it 'scary' and unprecedented.ABC News Einasleigh update 120

Other active: Major floods on Flinders at Walkers Bend (8.54m steady), moderate on Thomson and Suttor; Bruce Highway cuts persist. 119

Agricultural Devastation and Livestock Losses

Australia's beef heartland suffered immensely. By January 6, northwest producers reported 20,580 cattle missing/dead; totals climbed to 51,165 by January 12 and 68,000 surveyed by January 18, with graziers expecting higher. Australian Agricultural Company (AA Co) braced for earnings hits across three properties. 107 112

• Fencing: Hundreds of km destroyed.
• Infrastructure: Roads, equipment lost.
• Comparisons: Worse than some 2019 events in scale for northwest.

Infrastructure Disruptions and Isolation

Roads: 30+ closed statewide early on; Gregory Developmental Rd at Einasleigh, Bruce Hwy north of Ingham, Mackay-Eungella Range (landslips). Rail: Mount Isa line closed Richmond-Cloncurry. 120

Power: 15,000 properties affected post-Koji; telecoms down in central QLD. 117 SES calls surged to 158 in one day. Rockhampton's Fitzroy peaked moderately, flooding low-lying areas but less than feared (280 vs 480 properties). 14

Human Impact: Rescues, Stories, and Resilience

Emergency crews rescued dozens, including three from floodwaters near Clermont. No confirmed fatalities directly linked yet, but conditions life-threatening; police warned against travel. 117

Stories: Ashleigh Brieffies in Clermont needed boat/helicopter; Einasleigh's mayor Barry Hughes: 'massive amount of water'; hotelier Tayla Wellby: 'never seen anything like this'. Communities rallied, but isolation strains mental health. 120

Government Response and Funding

Premier David Crisafulli chaired disaster meetings, noting 'welcome rain' but flood risks. Federal/state committed $38m initially, then $26.6m more: $9.98m small biz, $4.26m mental health, $21.5m primary producer grants (up to $75k). 97 118

• Personal Hardship Assistance: 20+ LGAs.
• Recovery Grants: Cleanup, fencing, equipment.
• SES: High demand, app-based requests.

Economic Implications and Ripple Effects

Beef industry ripple: NSW cattle prices may rise from supply shortages. Substantial costs for producers, but agriculture resilient per experts. Broader: Tourism hit in coastal areas, insurance claims surge; levees planned (e.g., $10m Thargomindah). 111

Climate Context and Future Outlook

Warming atmosphere fuels intense monsoons; events like this 5x more likely per studies. Floodwaters may linger weeks/months in northwest; BoM watches for further troughs. New levees/floodways ($15m SW QLD) boost resilience. 31
