"Willy-Willy" in Australia: An Aboriginal Term for Tropical Cyclone

In Australian English, willy-willy (also whirly-whirly) traditionally refers to a dust devil — a small, short-lived whirlwind lifting dust/debris in the Outback. However, in some regions (especially tropical north), it's used colloquially for a tropical cyclone (hurricane/typhoon equivalent).

Clarification:

• Meteorological definition: Dust devil (clear-sky, thermal vortex, <1 km high, <10 m wide).
• Colloquial usage: Sometimes applied to severe tropical storms (e.g., "Cyclone Tracy was a big willy-willy").
• Origin: Likely from Aboriginal languages (e.g., Yindjibarndi wirlu-wirlu — whirlwind).

Official weather warnings use "tropical cyclone" (Category 1–5). "Willy-willy" remains a colorful bush term for both dust devils and, loosely, cyclones.
