Individual sharks can be killed if they pose a serious threat to public safety under orders from WA's Fisheries Department.  * Last unprovoked death: 60-year-old female diver at One Mile Reef, June 2016  * The state government announced a shark management strategy in 2015 including coastal aerial patrols, satellite listening stations, in-water surveillance trials, drones and drum lines. A trial of two eco-friendly shark barriers was called off this year after they failed to withstand rough conditions.  * Great white sharks are a protected species, but the federal government has signalled it will consider a cull on NSWs north coast after 17-year-old surfer Cooper Allen was attacked at Ballina on Monday.  * Last unprovoked death: 41-year-old male surfer at Shelly Beach, Feb 2015  * The shark control program, introduced in 1962, relies on mesh nets and drum lines (large, baited hooks) at areas including the Gold Coast, Sunshine Coast, central and far north Queensland. There is also a 24-hour emergency shark hotline to report sightings or damaged equipment.  * Last unprovoked death: 48-year-old male swimmer at Palm Island, 2011  * The state's Primary Industries website advises the risk of a shark attack is "extremely low".  * Great white sharks are a protected species.  * Last unprovoked death: 23-year-old male diver at Glenelg, August 2005  * There are a number of shark refuge areas where fishing is prohibited to protect sharks.  * Last unprovoked death: 35-year-old female diver at Tenth Island, June 1993  * Victoria restricts the intentional capture of great white sharks for commercial or game fishing, like all other states, in addition to greynurse, elephantfish, school and gummy sharks.  * Last unprovoked death: Mornington Peninsula, 1987  * Tiger and bull sharks live in NT waters but are not considered as much of a threat as crocodiles.
