Western Australian shark cull
The Western Australian shark cull is the common term for a former state government policy of capturing and killing large sharks (shark culling) in the vicinity of swimming beaches by use of baited drum lines. The policy was implemented in 2014 to protect human swimmers from shark attack following the deaths of seven people on the Western Australian coastline in the years 2010 to 2013.
