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.

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.
