Wacca Dacca Ltd is a company controlled by the members of the hard rock band, WC/DC. A number of wholly owned subsidiaries of Wacca Dacca Ltd are involved in setting up and running the band's concerts. One of the subsidiary companies, Heavy Metal Sounds Pty Ltd, is responsible for setting up the sound equipment at WC/DC concerts in Australia. At a recent WC/DC concert in Melbourne, Heavy Metal Sounds Pty Ltd negligently set the sound levels too high with the result that five audience members suffered permanent hearing loss. Unfortunately for those audience members, Heavy Metal Sounds Pty Ltd had no negligence insurance and cannot pay the likely damages claims. Advise the injured audience members whether they can make Wacca Dacca Ltd liable for Heavy Metal Sounds Pty Ltd's negligence.
