There have been questions regarding Australia's cyclone wind scale vs USA wind scale. Here is the answer.
The severity of a tropical cyclone is described in terms of categories ranging from 1 (weakest) to 5 (strongest) related to the zone of maximum wind gusts as shown in this table.
Note: corresponding sustained winds and central pressure are also provided as a guide. Stronger gusts may be observed over hilltops, in gullies and around structures.
Category Strongest Gust (km/h) Average Maximum Wind (km/h) Central Pressure (hPa) Typical Effects
1 < 125 63 - 88 > 985 Negligible house damage. Damage to some crops, trees and caravans. Craft may drag moorings
2 125 - 164 89 - 117 985 - 970 Minor house damage. Significant damage to signs, trees and caravans. Heavy damage to some crops. Risk of power failure. Small craft may break moorings.
3 165 - 224 118 - 159 970 - 955 Some roof and structural damage. Some caravans destroyed. Power failures likely. (e.g. Winifred)
4 225 - 279 160 - 199 955 - 930 Significant roofing loss and structural damage. Many caravans destroyed and blown away. Dangerous airborne debris. Widespread power failures. (e.g. Tracy, Olivia)
5 > 279 > 200 < 930 Extremely dangerous with widespread destruction. (e.g. Vance)
