Region Definition:
Wind regions are pre-defined for the whole of
Australia by the Australian Standard 1170.2.
The Wind Region is an independent factor of
surrounding topography or buildings.
• Most of Australia is designated Region A which
indicates a Regional Wind Velocity of 45 m/s with
wind average recurrence of 500 years.
• Some areas are designated Region B (57 m/s).
Local authorities will advise if this applies in your
area.
• Region C areas (69 m/s) are generally referred to
as Cyclonic and are generally limited to northern
coastal areas. Most Region C zones end 100km
inland.
• Region D (88 m/s) is Australia's most extreme
Cyclonic Region, located between the town of
Carnarvon and Pardoo Station in Western
Australia.
