to have an adverse effect on tourism. Opponents to the policy claim that baiting and culling sharks (particularly the great white shark, which is a federally protected species) to be inhumane, environmentally irresponsible, and ineffective at reducing the incidence of shark attack. Environmental concerns include the bycatch of other marine species, drowning of undersize sharks caught on the hooks and the impact on globally declining shark populations, particularly the great white shark, which is listed on the IUCN Red List as "vulnerable". The IUCN lists global threats to great white sharks to include targeted commercial and sports fisheries, protective beach meshing, and "media-fanned campaigns to kill Great White Sharks after a biting incident occurs". Some people against the policy also believe drum lines have the potential to attract sharks to popular beaches.

Backlash Protesters have drawn criticism for going to extremes to show their displeasure with the policy, including threatening the lives of cabinet ministers and a fisherman's family. The premier's office was also targeted in an attack. Queensland's shark control program manager Jeff Krause said "I'm surprised and disgusted at the extent that they (protesters in WA) are prepared to threaten and vandalise," referring to the threats that prompted at least one contractor to withdraw from the tender process in WA. "Everyone has got their opinion and they are entitled to it and I understand that people say it's the sharks' domain, but I also understand the senseless waste of human life and we have the capability to reduce that
