Traditional Australian bullroarer featuring unique Australian art. Our bullroarers make the perfect souvenirs from Australia or a unique gift for anybody interested in the Australian culture. These bullroarers are made from the traditional Australian brigalow hardwood. The bullroarer is a musical, communication and warning device historically used by First Nations people to communicate over great distances. When spun, the low-frequency component of the sound travels extremely long distances, clearly audible over many miles on a quiet night.
