Heavy rain and hail damage crops in parts of South Australia after violent storms swept the Riverland and Mallee late on Tuesday, 20 October 2026. The timing hurts. Farmers had finally moved past years of drought, and many were expecting a record-breaking harvest. At one Mallee property, a few minutes of severe weather undid months of work.
What Happened in the Riverland and Mallee
Storm cells crossed the western Riverland and Mallee late on Tuesday, bringing intense rain and hail. At Kamora Park Poll Merino Stud in Sandalwood, about 175 kilometres east of Adelaide, roughly 30 millimetres fell in about ten minutes. Hail stripped some crops down to bare stalks. Stud principal Katelyn Boughen said the stones were up to a centimetre across and looked like snow on the ground. She described the sound on the shed roof as a rapid pinging, like small gunshots.
In Lameroo, locals reported about 35 millimetres of rain and hail within an hour, enough to flood the main street. The Bureau of Meteorology said the western Riverland, parts of the Mid North, the Murraylands and the North East Pastoral District were hit hardest.
Rainfall Totals Across the Affected Region
Totals varied sharply from town to town, which is typical of thunderstorm rainfall. Some figures below come from the Bureau of Meteorology and some from local reports.
| Location | Reported rainfall | Notes |
|---|---|---|
| Lameroo (Mallee) | About 35 mm | Rain and hail within an hour; main street flooded |
| Kamora Park, Sandalwood | About 30 mm | Fell in roughly 10 minutes; hail up to 1 cm |
| Ponderosa | 22 mm | Bureau of Meteorology |
| Halidon | 20 mm | Resident report |
| Loxton | 16 mm | Resident report |
| Mount Mary | 16 mm | Bureau of Meteorology |
| Bakara Well | 13 mm | Bureau of Meteorology |
Crop and Property Damage at Kamora Park
The Boughen family’s losses show how localised hail damage can be. A lupin crop on a corner of the property, one the family had spent about three years trying to grow to cut feed costs, was badly hit. Katelyn Boughen suspected at least half of it was damaged, though the final figure was not yet known.
Her aunt, Anne Boughen, estimated the storm destroyed about a quarter of the property’s crop, around 400 hectares. The damage was not limited to crops:
- Deep gutters were washed through paddocks.
- Sheep feeders were smashed.
- Trees were stripped of leaves, which covered the roads.
- Steam rose off the road surface after the hail.
Anne Boughen said she had never seen anything like it. Katelyn pointed out that the area normally gets too little rain, which made the sudden downpour more shocking.
Why the Timing Hurts
This year’s above-average rainfall broke years of drought across much of South Australia and lifted both crop prospects and morale. Forecasts for a record harvest meant growers were counting on a strong return after lean seasons. Storms like this one show that a good season can still be cut short by one bad afternoon. Katelyn Boughen summed it up by saying farmers are at the mercy of Mother Nature, and that every year brings something new to handle.
The damage is also uneven. One paddock can be flattened while a neighbouring property is untouched. Regional harvest forecasts may stay strong overall even as individual farms take heavy losses.
What Growers Typically Do After a Hail Event
Farmers and agronomists generally follow the same steps after severe hail:
- Document everything. Take dated photos and video of damaged paddocks, fences and equipment before cleanup begins.
- Contact your insurer early. Check what your policy covers and what notice period applies.
- Assess before deciding. Some crops recover partly depending on growth stage, so get an agronomist’s view before writing off a paddock.
- Check for erosion and runoff damage. Washed-out gutters can affect later sowing and harvest access.
- Repair feed and water infrastructure first. Livestock needs come ahead of tidying up.
This is general guidance, not advice for any one farm. Policy terms and crop recovery vary, so confirm the details with your insurer and agronomist.
Frequently Asked Questions
Where did the heavy rain and hail hit?
The storms hit parts of the western Riverland and Mallee in South Australia late on Tuesday. Sandalwood, Lameroo, Halidon and Loxton recorded rain, and the Bureau of Meteorology said the Murraylands, parts of the Mid North and the North East Pastoral District were also affected.
How much crop was lost?
At Kamora Park in Sandalwood, one family member estimated about a quarter of the crop, roughly 400 hectares, was lost. A lupin crop may be at least half damaged, but that figure is still an estimate.
Will this stop South Australia’s record harvest?
Nothing reported suggests the statewide outlook has changed. The losses are local, and each property is still assessing its damage.
How much rain fell in the storms?
Reports ranged from 13 millimetres at Bakara Well to about 35 millimetres at Lameroo. Kamora Park received around 30 millimetres in roughly ten minutes.
