Warnbro Sound

Warnbro Sound, an Indian Ocean embayment, is located on the coast of Western Australia south of Cape Peron, 25 kilometres south of Fremantle. It is a semi-circular sound, 7 kilometres wide with 11 kilometres of shore. The area was surveyed in 1837 by Surveyor-General John Septimus Roe, who named it in 1838; the etymology of the name is unknown. The Perth suburb of Warnbro is named after it.In summer 2014–2015, the beach at Warnbro Sound was closed for a number of days while the state Department of Fisheries pursued a great white shark that was frequenting the area. The impact of the department's "catch-and-kill" order on beach safety and scientific research was the subject of some controversy.
