Does Minister Furner listen to the QLD shark control Scientific Working Group?

More than 78 humpback whales have been entangled in shark nets since 2001 (AMCS). These magnificent animals are intelligent and live up to 50 years. They are protected under the Environment Protection and Biodiversity Conservation Act 1999 and under state legislation of Queensland (QLD), New South Wales (NSW) and Victoria. Humpback whale population numbers are recovering, but they are still considered vulnerable (Australian Museum).


Despite the protections offered by Commonwealth and state legislation, the number of whales becoming entangled in shark nets increases during the annual whale migration along the east coast of Australia (DAF). To reduce the number of whale entanglements, the NSW Department of Primary Industries removes the shark nets during the core period of the

whale migration from May to August each year.

However, in QLD the shark nets remain in place all year round. This is despite calls from the QLD shark control Scientific Working Group that shark nets be removed and replaced with drumlines during the annual whale migration. Drumlines pose a lesser threat to whales than shark nets, although drumline entanglements show that this risk is not zero.


Entangled whales can drown, be predated upon or die from injury, stress and exhaustion. In August 2021, a young humpback struggled in shark nets on the Gold Coast for more than two days before it was released. The brave crews involved in its release did their best, but there were concerns about the whale’s chances of surviving, as it was released dragging chain and shark net buoys (Sea Shepherd).


In QLD, Mark Furner the Minister for Fisheries says the protection of human life always comes first, but whale entanglements are potentially life-threatening to humans too. The Minister seems to forget that crews are risking their lives when trying to free entangled whales, and also that there is no scientific evidence that shark nets keep beachgoers safe.


There are other risks to human life too—a whale in distress gets the attention of large sharks. A fully grown humpback whale can grow to 18 metres long and weigh about 30 tonnes. The thrashing and distress calls of the whale lure sharks closer to shore, actually increasing the likelihood of human-shark encounters. It is worth noting that there is no protocol to close beaches when shark nets are known to contain catch (essentially meaning they are now baited), not even when that catch is as large, as visible, and such a well-known shark attractant like a distressed humpback whale.


There are modern non-lethal alternatives available to keep beachgoers safe. There is no justifiable reason to continue putting human and marine life at risk by using outdated shark control measures, especially shark nets. This is not just our view, but also that of the Scientific Working Group.


The QLD government might be able to set aside the views and recommendations of the Scientific Working Group for now, but ‘there is mounting social pressure for management agencies to deal with the social and safety issues of shark bites in a non-destructive way’ (Pepin-Neff and Wynter, 2017; Simmons and Mehmet, 2018; as cited in Colefax et al).

Will you help us keep that pressure mounting?
