Formed in the Coral Sea on 17 March, Narelle rapidly intensified into a Category 5 system with sustained winds of up to 225 km/h and gusts nearing 285 km/h before it made its first of four landfalls on the Cape York Peninsula.
It was, by the Bureau of Meteorology's own count, one of the most unusually long-lived and geographically sweeping cyclones in recorded Australian history. 103 separate Tropical Cyclone Advice messages were issued across Narelle’s 8-day journey through Queensland, the Northern Territory, and Western Australia.
But once the social media frenzy and news headlines fade, what remains is something far less visible and far more dangerous: water. For rural communities and farmers across the country, this threat is only just the beginning.
What the Water Leaves Behind
The popular image of a cyclone tends to focus on wind: rooftops peeling away, trees snapping, cars flying. The longer crisis is almost always what the rain does after the storm.
For farmers, the sequence is grimly familiar.
Floodwaters strip fertile topsoil from cropping land, removing the organic matter and nutrients that took decades to accumulate. Farm activities can be interrupted by waterlogged soils for days or even weeks, and the removal of topsoil through water erosion leads to long-term yield declines that do not recover quickly.
Livestock losses in flood events can be staggering. The 2019 Queensland floods alone killed hundreds of thousands of cattle. The more recent Queensland floods of 2025, worsened by Cyclone Alfred, killed or displaced more than 144,000 livestock across an area twice the size of Victoria, destroying thousands of kilometres of fencing and private roads in the process.
Surviving animals also carry their own set of problems. Virulent footrot spreads rapidly in warm, wet conditions. Clostridial diseases linked to contaminated soil and water move through herds, bringing with them three-day sickness and other vector-borne illnesses.
Machinery and equipment sheds that look intact from the outside may already be compromised. In low-lying rural properties, water pools beneath slab floors and inside wall cavities for weeks. By the time the damage becomes visible, it is significantly more expensive to fix.
The Long Reach South
A common and costly assumption is that cyclone flooding is a far-north problem. It is not, and communities in regional Victoria and New South Wales have learned this the hard way.
Narelle renewed flooding across the Northern Territory, including along the Daly River, and the Bureau of Meteorology issued minor to major flood warnings for several river systems as the ex-tropical system pushed rainfall deep into catchments that eventually drain southward.
Water generated by northern weather events flows through the Murray-Darling river system over days and weeks, arriving in communities along the Murray corridor, including towns across the Yarrawonga region, long after the cyclone has cleared the front pages.
This delayed arrival is what makes the risk so underestimated. The emergency feeling has passed. Attention has moved elsewhere. But the river is still rising, and there are risks of further damage.
Getting In Early Is Crucial
Once floodwater has entered a structure, the clock is running. Moisture that is extracted and treated within the first few days can be remediated without major structural intervention. Left for weeks, it generates mould, accelerates rot and can compromise the integrity of the building itself.
For properties on Melbourne's urban fringe and in regional towns across Victoria, professional assessment after a flood event is not optional if the goal is genuine recovery. Services like flood damage in Melbourne exist specifically for this window. Experts like Melbourne Flood Emergency work with both residential and commercial properties to extract moisture, identify hidden water damage and restore buildings to pre-disaster condition before secondary damage takes hold.
ABARES modelling found that climate-driven changes between 2001 and 2020 reduced average annual farm profits by an estimated 23%.
With events like Narelle intensifying in frequency and scale, the pressure on rural businesses and regional infrastructure will only grow. For farming operations already carrying the weight of years of climate-related losses, it can determine whether a business survives the season at all.
