Rain may delay harvest but support summer crops in northeast Australia

The Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) said rainfall in the northeast created both support and harvest risks for farmers in its October 22 weekly report. Cropping regions in Queensland and northern New South Wales received 10–100 millimetres in the week ending October 21. ABARES said the falls could help summer-crop development and pasture growth but were also likely to delay winter-crop harvesting. The two effects touch different seasons and farm schedules: soil moisture can aid summer planting and pasture while making it harder to remove mature winter crops from fields. The balance depends on the amount of rain and the crop’s development stage. The report describes possible effects; it does not say that harvest losses or quality downgrades had already occurred.

The national picture shows why rainfall totals need regional context. Much of Queensland recorded 5–200 millimetres, with the far north and southwest as exceptions; some parts of northeastern New South Wales received up to 100 millimetres. Scattered areas of southern New South Wales, South Australia, the Northern Territory and Western Australia received 5–25 millimetres, with isolated places reaching 50 millimetres. By contrast, much of Tasmania and Victoria had little or no rain. ABARES said cropping regions had significant falls in the northeast and limited rainfall in southern areas. A national aggregate could hide that divide. For farmers, a rainfall figure is useful only when it is linked to where it fell, how much arrived and what work was underway in the paddock.

The report’s forecast for October 22–29 must be kept separate from observed rainfall. Rain was forecast across much of the eastern two-thirds of Australia, while northwestern Western Australia was expected to remain dry or receive little. For cropping areas in Queensland and northern New South Wales, the forecast range was 25–150 millimetres; Victoria, South Australia and central and southern New South Wales were forecast to receive 10–50 millimetres. Western Australian cropping regions were forecast to receive 5–10 millimetres. These were model-based forecasts from the Bureau of Meteorology, not measurements. ABARES notes that model outputs are not adjusted by weather forecasters and advises readers to check local forecasts and official warnings. They provide a planning signal, not a replacement for local observations or safety advice.

The possible benefit and risk of rain can affect different stages of the crop calendar. ABARES said soil moisture could support winter-crop grain filling and pasture in the southeast, as well as summer-cropping activities in the northeast. But Queensland and northern New South Wales had already received rain the previous week. Further rain could delay winter harvest there and raise the risk of grain-quality downgrades from excess moisture at harvest. This illustrates why rainfall is not simply a positive or negative measure. The same event may aid pasture growth in one paddock and postpone machinery access in another. The report presents those outcomes as risks and prospects, not confirmed damage. It does not quantify how much harvest work might be delayed or how many tonnes could be affected.

The seasonal outlook is a different time horizon from the short-range forecast. The Bureau of Meteorology’s November 2026–January 2027 outlook cited by ABARES indicated below-average rainfall was likely to be limited to parts of the far southeast and northern tropics, while above-average rain was more likely across much of western and central Australia and parts of inland and southern Queensland and northern New South Wales. El Niño was strengthening, a condition that typically raises the chance of drier spring conditions in parts of eastern Australia, but the report says rainfall outcomes vary with other climate influences. The Indian Ocean Dipole was neutral, while the Southern Annular Mode was trending negative and forecast to return to neutral. No single climate indicator determines the rainfall outcome for a particular region.

ABARES’s Australian Agricultural Drought Indicators (AADI) section explains how climate and prices feed into a forecast of farm business profits. As of the end of September, broadacre farm profits nationally in 2026–27 were forecast at the 73rd percentile of the historical distribution, or average or better. The report’s summary states the 72nd percentile, while the detailed section gives 73. Both are forecasts, not realised farm profits. AADI compares current farm characteristics with simulated climate and price conditions across the past 33 years. A percentile does not mean every farm will reach the same outcome or that a farmer’s income will rise by a specified amount. It is a modelled position relative to a historical benchmark, based on stated climate and price inputs. The report does not explain the difference between its summary and detailed percentile; it should not be attributed to rounding without an explanation from ABARES.

Regional differences sit beneath the national estimate. ABARES said the strongest forecast conditions for broadacre farm profits were concentrated in the Northern Territory, Queensland, central Western Australia, northern South Australia and western New South Wales, where favourable climate coincided in some areas with strong livestock prices. In contrast, parts of northwestern and southwestern Western Australia and isolated areas of southeastern Queensland and northeastern New South Wales had below-average forecasts. In the report’s Australian Agricultural and Grazing Industries Survey regional estimates, Western Australia’s Central and South Wheat Belt was at the 28th percentile and Queensland’s Eastern Darling Downs at the 34th. Those examples show why the national 73rd-percentile estimate does not describe local conditions. The forecast is bounded by its regional classifications and current farm characteristics.

Water storage declined over the week. Using Bureau of Meteorology data, ABARES reported that Murray-Darling Basin storage fell by 97 gigalitres between October 15 and October 22 to 14,931 gigalitres, or 67% of total capacity. That volume was 77 gigalitres below the same time a year earlier. The report combines a one-week change with a basin storage level on a specific date. Storage alone does not tell an individual producer’s irrigation allocation or usable water access; allocation rules, connected systems and market constraints also matter. ABARES said the Victorian Murray allocation price below the Barmah Choke fell to A$324 per megalitre on October 22 from A$349 a week earlier, while three named transfer routes were closed. These are separate storage and market indicators.

The weekly commodity tables form another distinct part of the report. For the week average ending October 21, the Eastern Young Cattle Indicator was 968 Australian cents per kilogram of carcase weight, up 2% on the previous week. The National Trade Lamb Indicator was 1,162 cents per kilogram carcase weight, a 1% rise. Australian Premium White wheat at Adelaide on a free-on-board basis remained at A$430 per tonne, while canola at Kwinana was A$796 per tonne, down 1%. These are selected market indicators, not the farm-gate price every producer received. The report also shows that the latest observation date varies by series: for example, its light-steer export indicator for Indonesia was dated September 9. Readers should not treat each item as a same-day market quote.

The practical meaning of the October 22 update lies in reading its regions and time horizons together, rather than relying on a single rainfall or profit figure. Rainfall observed in the previous week, the next eight-day forecast and the November-to-January outlook are different evidence types. The weekly decline in Murray-Darling storage and a particular allocation price are separate water-market measures. ABARES’s September Australian Crop Report had also described improved winter-crop conditions in southern regions and weaker planted-area and yield expectations in Queensland and northern New South Wales for 2026–27. That earlier context helps explain seasonal differences, but the crop report and weekly weather update were prepared at different dates and answer different questions. Outcomes at individual farms still depend on local rain, crop stage, soil moisture and water access.
