Autumn provides the critical window for winter preparation on Australian rural properties. Cold, wet, and windy conditions strain livestock, damage gardens, and expose infrastructure weaknesses. Systematic preparation in March and April prevents winter crises and protects your investment in animals, crops, and equipment.
Bureau of Meteorology forecasts for winter 2026 indicate above-average temperatures across most of Australia, with increased rainfall likely for most of southern Australia. Despite warmer predictions, cold snaps, wet conditions, and strong winds still threaten unprepared properties. This guide covers essential preparation tasks across livestock care, garden management, and infrastructure maintenance.
Understanding Winter 2026 Weather Patterns
The 2025-26 La Niña is weakening, with neutral conditions expected through autumn 2026. Rainfall is likely to be above average in northern Australia and below average for most of southern Australia during autumn.
What this means for property preparation:
Southern properties face drier conditions leading into winter but should still prepare for cold, wet weather events. Northern properties experience wetter conditions through autumn before transitioning to drier winter patterns.
Above-average day and night temperatures are very likely across most of Australia for winter 2026. However, temperature forecasts don’t eliminate cold stress risks. Overnight frosts, sudden cold fronts, and wet, windy conditions still occur during warmer-than-average winters.
Properties in southern regions should monitor Bureau of Meteorology sheep grazier warnings. These warnings alert farmers about cold or wet conditions that could harm livestock, using combinations of wind, temperature, and rain thresholds.
Livestock Preparation for Winter
Cold stress affects livestock productivity, health, and survival. Proper preparation protects animals and maintains production through challenging months.
Assessing Body Condition Before Winter
Evaluate body condition scores for all stock during March and early April. Animals undernourished before winter lack fat reserves to handle increased energy requirements in cold conditions.
Cattle and sheep should enter winter with moderate to good body condition. Thin animals struggle to maintain body temperature and face higher mortality risks during cold snaps.
| Livestock Type | Target Body Condition | Action if Below Target |
| Beef cattle | Body condition score 3-4 (out of 5) | Increase feed quality and quantity for 4-6 weeks before winter |
| Sheep | Body condition score 3-3.5 (out of 5) | Supplement with quality hay and grain; drench for parasites |
| Pregnant ewes | Body condition score 3.5-4 | Increase feed immediately; pregnancy toxaemia risk if too thin |
| Dairy cattle | Body condition score 2.5-3 (out of 5) | Adjust ration; consult nutritionist for lactating cows |
| Goats | Body condition score 3-3.5 (out of 5) | Increase browse access or quality hay supplementation |
Prioritise pregnant livestock, recently purchased animals, and young stock for body condition assessment and improvement. Pregnant stock are particularly at risk due to high feed and energy requirements. Not also that these are guidelines and that there can be significant variability based on specific breeds, environments and individual animal needs.
Shelter and Windbreak Assessment
Cold weather, particularly when combined with wet and windy conditions, can have severe impacts on sheep especially lambs and recently shorn animals. Adequate shelter is essential for all livestock species.
Inspect existing shelters during March and April:
Natural windbreaks including tree lines, forestry blocks, and topographical features should provide protection from prevailing cold winds. Layered shelter belts are effective in moderating wind speeds, with tall-growing open plantings reducing wind speeds downwind for distances of 25 to 30 times the height of the barrier.
Three-sided sheds and open-front structures should face away from prevailing winter winds (typically south-facing in southern Australia). Check roofs for leaks, repair damaged panels, and ensure drainage around structures prevents pooling water.
Portable windbreaks using round bales, shade cloth on frames, or temporary fencing can supplement natural shelter. Position these strategically in paddocks lacking natural protection.
Special shelter management may be necessary for calving cows and their calves, with small paddocks within sheltered areas along the edge of shelterbelts proving useful.
Planning for Lambing and Calving
Schedule lambing and calving to avoid peak cold and wet periods when possible. Properties in cold regions benefit from spring lambing (August-October) when conditions improve.
Prepare lambing and calving paddocks in autumn:
Select paddocks with best available shelter from cold winds. Studies have shown that in cold, wet and windy weather, lamb losses can be reduced by around 30% if flocks are provided good shelter.
Ensure adequate space to prevent overcrowding. Mob sizes should allow all animals access to shelter simultaneously.
Position water sources to prevent animals camping around water and blocking access. Provide multiple water points in lambing areas.
Identify isolation areas for sick animals, difficult births, or mis-mothered lambs requiring intervention.
Managing Recently Shorn Sheep
Recently shorn sheep may only have about three millimetres of insulating wool remaining, which can cause up to a three-fold increase in heat loss. Time shearing carefully relative to weather forecasts.
If shearing must occur before winter:
Move freshly shorn sheep immediately into best-sheltered paddocks. Freshly shorn sheep can be extremely difficult to move in cold weather.
High mortalities have occurred in mobs up to four weeks after shearing. Monitor weather forecasts closely for four weeks post-shearing and move sheep to better shelter if cold weather threatens.
Increase feed quality and quantity for shorn sheep. In cold conditions it is advisable to increase feed by 20%.
Winter Feeding Planning
In cold and wet conditions, stock use energy to keep warm, and drought-affected stock without fat reserves cannot handle increased energy requirements.
Stock and test hay supplies during autumn:
Calculate hay requirements based on stock numbers and expected feeding duration. Budget for 2-3kg per adult sheep daily, 15-20kg per adult cattle beast daily during supplementary feeding periods.
Test hay quality. Some hay is very poor quality, high in fibre but low in energy and protein which are the most important factors when supplementary feeding stock.
Consider energy-dense supplements including grain, pellets, dried distillers grain, or lupins for late pregnancy and lactation when green feed is limited.
Store hay under cover or on well-drained sites with adequate protection from weather. Spoiled hay wastes money and provides poor nutrition.
Water System Winterisation
Livestock water consumption continues through winter. The daily energy intake needed for a freshly calved cow or heifer with a calf at foot is double that required to maintain a dry cow. Adequate water remains essential.
Prepare water systems in autumn:
Check all troughs, tanks, and automatic waterers for leaks, damage, or malfunction. Repair before cold weather complicates work.
Clean water systems thoroughly. Waterers should be regularly cleaned to help reduce bacteria, fecal matter, and other solids that may build up over time and affect water taste.
Insulate exposed pipes in frost-prone areas or install pipe insulation. Burst pipes during frosts create expensive emergency repairs.
Ensure backup water supply options exist. Identify alternative water sources if primary systems fail during cold weather.
Position water sources near shelter areas to reduce livestock energy expenditure travelling between water and protection.
Health Management Before Winter
Monitor pregnant livestock regularly to ensure you pick up on health and welfare issues early, allowing you to lessen the impact they may have on productivity.
Complete health tasks during autumn:
Drench for internal parasites before winter. Worm burdens increase during wet conditions and weaken animals entering cold weather.
Vaccinate according to property programs. Complete pre-winter vaccinations for clostridial diseases (5-in-1 or 6-in-1 vaccines) at least 4-6 weeks before lambing or calving.
Trim hooves on sheep and goats. Overgrown hooves contribute to lameness, and wet winter conditions exacerbate footrot problems.
Treat lice infestations before they worsen during winter. Animals huddling together for warmth accelerates lice spread.
Identify and separately manage vulnerable animals including those in poor condition, sick animals, or those with respiratory disease history.
Garden and Orchard Winter Preparation
Autumn garden tasks set up productive winter crops and protect perennials through cold months.
Planting Winter Vegetables
March and April suit cool-season vegetable establishment across most Australian regions. Plant transplants or direct seed depending on local climate:
Suitable for immediate planting (March-April):
- Broad beans, peas, and snow peas
- Broccoli, cauliflower, and cabbage seedlings
- Asian greens including bok choy, pak choy, and Chinese cabbage
- Lettuce, rocket, and salad greens
- Spinach and silverbeet
- Onions, garlic, and shallots
- Carrots, beetroot, and turnips
Plant garlic cloves during April for harvest the following spring. Select virus-free seed garlic and prepare well-drained beds.
Establish brassica seedlings early enough to develop before slowing winter growth. Transplant when seedlings reach 10-15cm height.
Protecting Fruit Trees and Perennials
Fruit trees require minimal autumn intervention but benefit from targeted preparation:
Apply dormant oil sprays to deciduous fruit trees after leaf fall. This controls overwintering pests including scale insects and mites.
Prune summer-fruiting trees and vines after harvest. Stone fruits (plums, peaches, apricots) should be pruned immediately after fruiting to reduce disease risk. Winter pruning suits pome fruits (apples, pears).
Mulch around fruit trees before winter. Apply 75-100mm of organic mulch maintaining clear space around trunks. Mulch moderates soil temperature, conserves moisture, and suppresses weeds.
Protect cold-sensitive plants including citrus, avocados, and tropical fruits in frost-prone areas. Install frost cloth frames or temporary windbreaks around vulnerable plants.
Soil Building for Spring
Autumn provides ideal conditions for soil improvement:
Apply compost and organic matter to garden beds after clearing summer crops. Winter rainfall gradually incorporates amendments without leaching nutrients.
Plant green manure crops on unused beds. Legume green manures including field peas, faba beans, or vetch fix nitrogen while protecting soil structure through winter. Cereal green manures like oats or rye produce biomass for incorporation before spring planting.
Sheet mulch areas for spring conversion. Layer cardboard, compost, and mulch over grass or weeds. Winter decomposition prepares beds for spring planting.
Lime acidic soils during autumn if soil tests indicate pH below 6.0. Winter rainfall activates lime and raises pH before spring planting.
Maintaining Irrigation Systems
Irrigation demand decreases during winter but systems require maintenance:
Flush and clean irrigation lines before reduced use periods. Remove filters, clean thoroughly, and inspect for damage.
Repair leaks identified during summer operation. Winter provides opportunity for system repairs without affecting active crops.
Drain and store portable irrigation equipment including sprinklers and hoses. Prevent frost damage to equipment left exposed.
Adjust irrigation schedules and timers for reduced winter evapotranspiration. Overwatering during cool, wet weather encourages root diseases.
Infrastructure and Equipment Maintenance for Winter
Cold, wet weather exposes infrastructure weaknesses. Autumn maintenance prevents winter failures.
Shelter and Building Inspection
Comprehensively inspect all farm buildings during March and April:
Roof and gutter systems: require particular attention. Clear gutters and downpipes of debris. Blocked gutters overflow during winter rains, causing water damage to buildings and surrounds.
Check roof sheeting for rust, damage, or loose fasteners. Replace damaged sections before winter storms worsen problems.
Inspect flashing around chimneys, vents, and roof penetrations. Deteriorated flashing allows water entry damaging building structures and contents.
Wall and door systems: should seal effectively against wind and weather. Check for gaps, damaged cladding, or non-closing doors allowing wind and rain entry.
Lubricate hinges and latches on shed doors and gates. Ensure doors close and latch securely against winter storms.
Floor drainage: prevents water pooling inside buildings. Check floor gradients and drains function correctly. Clear drainage outlets of debris.
Fencing Maintenance
Winter weather stresses fencing infrastructure. Identify and repair problems during autumn:
Walk fence lines systematically, noting damaged posts, broken wires, or compromised netting. Prioritise repairs in paddocks designated for winter use.
Tighten loose wires and replace broken strands. Fence tension naturally decreases over time, and winter wind loads exploit slack fencing.
Check electric fence systems thoroughly. Replace degraded insulators, repair or replace faulty energisers, and ensure earth stakes contact moist soil effectively.
Clear vegetation from fence lines. Grass and shrubs against fences create short circuits in electric systems and accelerate wire corrosion.
Replace rotten timber posts identified during inspections. Mark problem posts for replacement during suitable weather conditions.
Machinery and Equipment Service
Service tractors and equipment before winter reduces downtime during busy periods:
Change engine oil and filters on tractors and equipment. Cold weather reduces oil viscosity, and fresh oil ensures optimal engine protection.
Check coolant antifreeze levels in liquid-cooled engines. Top up as necessary to protect engines from frost damage.
Inspect tyres for damage, correct inflation, and adequate tread. Winter mud demands good tyre condition for traction and safety.
Grease all grease points on equipment. Water washes away lubrication during wet weather, accelerating wear.
Test battery condition and charge levels. Cold weather reduces battery performance. Replace weak batteries before they fail during cold snaps.
Service and sharpen cutting equipment including slashers, mowers, and chainsaws. Prepare equipment for pruning, firewood cutting, and property maintenance during winter.
Store unused equipment under cover. Protect machinery from weather exposure when not regularly used during winter months.
Water Infrastructure Checks
Beyond livestock water systems, check property-wide water infrastructure:
Inspect dams and overflow structures before winter rains. Clear spillways of debris and vegetation. Check dam walls for cracks, erosion, or animal damage requiring repair.
Test bore pumps and pressure systems. Ensure backup systems function correctly before becoming necessary during cold weather.
Check water tank foundations and supports. Winter storms can damage inadequately secured tanks. Tighten straps and check support stability.
Clean roof gutters feeding rainwater tanks. Maximise winter rainfall capture for water security through following dry months.
Insulate or heat-trace vulnerable water pipes. Prevent burst pipes during frost events in cold regions.
Firebreak and Access Maintenance
While fire risk typically reduces during winter, maintain access and firebreaks:
Slash or graze fire breaks to manageable fuel levels. Maintain clear widths allowing machinery and vehicle access.
Clear fallen branches and debris from access tracks. Winter storms drop branches that obstruct farm roads and tracks.
Grade gravel roads and tracks before winter rains. Repair erosion damage and ensure adequate drainage prevents track degradation during wet weather.
Install or maintain gates allowing vehicle access throughout property. Check gate hardware and hinges function smoothly.
Emergency Preparedness
Prepare for winter emergencies including power outages, flooding, or severe cold snaps:
Service backup generators and ensure adequate fuel storage. Test generators under load before winter increases usage likelihood.
Stock emergency supplies including spare fencing materials, veterinary supplies, livestock feeding equipment, and basic building repair materials.
Identify emergency shelter areas for livestock if extreme weather threatens primary paddocks. Plan animal movement routes and logistics before crises develop.
Maintain communication equipment including mobile phones, two-way radios, and backup power for devices. Ensure contact numbers for veterinarians, stock agents, and emergency services are current and accessible.
Develop written emergency plans for different scenarios including flooding, extended power outages, or severe cold events. Brief family members and staff on emergency procedures.
Regional Winter Preparation Considerations
Winter preparation priorities vary across Australian climatic zones.
Southern Regions (Victoria, Tasmania, Southern NSW, South Australia)
Southern properties face coldest conditions and highest winter rainfall. Priority preparation includes:
Maximise livestock shelter from cold winds. Southern Tablelands livestock farmers compete with particularly cold and wet weather.
Prepare for sheep grazier warnings and rapid weather changes. Cold fronts bring sudden temperature drops and wet, windy conditions.
Ensure adequate hay supplies for extended feeding periods. Southern winters limit pasture growth for 3-4 months.
Protect cold-sensitive plants with frost cloth or temporary structures.
Central and Northern Regions (Queensland, Northern NSW, Northern Territories)
Northern properties experience milder winters but face different challenges:
Prepare for dry winter conditions. Rainfall is likely to be above average in northern Australia during autumn but transitions to drier conditions in winter.
Maintain water supplies during dry winter months. Ensure adequate dam storage or bore access.
Plan for reduced pasture growth during dry season. Supplementary feeding may become necessary.
Continue parasite management. Warmer conditions maintain year-round parasite pressure.
Frost-Prone Areas
Properties in frost-prone valleys or tablelands require additional preparation:
Protect sensitive crops with frost cloth or row covers. Establish covers before first frosts arrive.
Move cold-sensitive livestock to higher ground during frost events. Cold air settles in valleys, creating extreme frost risk.
Insulate water systems and check daily during frost periods. Livestock cannot meet their water requirements by eating snow. Similarly, they cannot rely on ice as water source.
