Australian Standard
The above map of Australia – extracted from the Australian Standard “Wind-regions-in-Australia-in-accordance-with-ASNZS-1170.2-2011”- refers to the following regions (with Terrain Category 2 and 10m reference height):
Potential wind speed is critical when selecting the correct Windsock material, a Frame — if necessary — and the Windsock Pole. Windsocks Australia has successfully deployed Windsocks across all regions in Australia and can advise on the appropriate Windsock for your region.
Wind Speed Data
Australia is divided into four wind regions, each with distinct design wind speed requirements. Understanding your region is the first step in selecting correctly rated Windsock equipment.
| Wind Region | Classification | Ultimate Design Wind Speed |
|---|---|---|
| Region A | Non-Cyclonic | ~ 146km/h |
| Region B | Non-Cyclonic | ~ 187km/h |
| Region C | Cyclonic | ~ 232km/h |
| Region D | Cyclonic | ~ 317km/h |
⚠ Cyclonic Regions
Wind Regions C and D are classified as cyclonic regions, requiring specially rated Windsock materials, Frames, and Poles designed to withstand significantly higher wind speeds.
Regional Guidance
Windsocks Australia has successfully deployed Windsocks across all regions in Australia. Understanding which wind region your location falls within is critical for selecting appropriately rated equipment that will perform reliably and safely.
Region Selection Guide
Standard Reference
For full details refer to AS/NZS 1170.2:2011. This standard provides the complete framework for determining wind actions on structures and is essential for engineers, builders, and facility managers selecting appropriate wind-rated equipment.
Key Takeaways
Region-Specific Selection
Wind speeds vary dramatically from 146km/h in Region A to 317km/h in cyclonic Region D. Select equipment rated for your specific region.
Cyclonic Considerations
Regions C and D are cyclonic zones requiring Heavy Duty Windsock materials, reinforced Frames, and engineered Poles to withstand extreme conditions.
