Wanderlust World Wanderlust World Australian police vehicles employ several distinct siren tones, each serving a specific operational need:
The classic long, rising-and-falling tone. Used for general patrol and emergency response; audible over long distances.
A rapid, staccato version of the wail. Often combined with the wail to cut through heavy traffic noise and attract attention at intersections.
A loud, continuous blast. Primarily used in New South Wales and Queensland for high-priority emergencies and to clear traffic aggressively.
A programmable speaker system that can reproduce wail, yelp, air horn, and other tones (e.g., "piercer," "hi-lo"). Increasingly standard across jurisdictions for versatility.
All sirens comply with state regulations on sound output and usage protocols.
