Efficacy of an ultrasonic device as a deterrent to dingoes (Canis lupus dingo): a preliminary investigation

Abstract

In April 2001, a 9-year-old child was attacked and killed by dingoes on Fraser Island, Australia. The Dingo Management Strategy formulated in response to this incident proposed ultrasonic deterrents as one of a number of non-lethal management techniques requiring further investigation. In this paper, we describe a preliminary examination of an ultrasonic deterrent to dingoes using four captive animals as test subjects. Although replication was minimal, the use of a simple experimental design, in combination with a flexible analytical technique, sufficiently demonstrated that the unit tested produced no measurable effect as a deterrent to test subjects.
