Shark chew incidents are uncommon however traumatic. They’re normally adopted by requires mitigation methods, a few of that are harmful or deadly to sharks – regardless of the very fact most sharks are timid and actively keep away from folks.
The “SharkSensible” method, adopted by the Queensland authorities, goals to teach and urge folks to take duty for decreasing the danger of shark bites by altering their very own behaviour. But can people change?
To discover out, we teamed up with three firms within the crusing constitution business within the Whitsundays space to higher perceive how folks have been utilizing the atmosphere, their information of shark sensible behaviours and to see if selling SharkSensible behaviours led to alter.
We discovered folks can and do change behaviour because of schooling – however for some, sadly, a “she’ll be proper” perspective nonetheless prevails.

Doing your half to be SharkSensible
Previous surveys had proven many water-users have been already conscious of some ways to cut back shark danger however there was room for enchancment.
Many SharkSensible behaviours are well-known, resembling not swimming at nightfall or daybreak when sharks could also be extra prevalent.
But we needed to search out out what else folks have been doing within the water and see if some key SharkSensible interventions made a distinction. The interventions included:
displaying folks a brief video earlier than they went out on the water
placing stickers on boats to remind folks find out how to scale back shark danger
making SharkSensible brochures accessible to company on boats
devoted waste disposal baggage got to 2 of the constitution boat operators, with the third performing as a management group.
We did surveys earlier than and after these SharkSensible instruments have been launched to see what modified.
We notably needed to know whether or not folks have been much less prone to do eight issues linked to increased shark danger within the Whitsundays space:
1. splashing within the water
2. swimming alone
3. swimming close to fishers
4. swimming at spots the place shark bites have occurred prior to now (on this case, in Cid Harbour)
5. throwing fish scraps within the water
6. throwing burley (a kind of bait, typically generally known as chum) within the water
7. fishing close to swimmers
8. throwing meals within the water.
Research means that by not doing these eight issues, we will make shark bites even rarer than they already are.
As nicely because the before-and-after surveys, we captured a pattern of garbage coming again on shore. This was so we might get an thought of whether or not fish and meat have been being saved or thrown overboard.
We additionally needed to see the place and when danger is perhaps increased. For instance, snorkelling in a busy anchorage or the place persons are fishing could enhance pointless risks. The hotter months of September to December have been mapped as potential increased danger for shark bites.
Our findings
We surveyed 228 vacationers (92 pre- and 136 post-intervention) and located:
a 8.9% discount in splashing or making noise when swimming or snorkelling
a 4.1% discount in throwing fish scraps overboard and
a 3.8% discount in folks fishing close to folks swimming.

We discovered most individuals have been conscious of those six behaviours:
following native signage
having a buddy when swimming, diving or snorkelling
avoiding swimming at daybreak or nightfall
swimming in clear water
conserving fish waste and meals scraps out of the water the place folks swim
avoiding swimming with faculties of bait fish or diving birds.
The lowest consciousness was for the final one, however after our intervention we noticed a 4.7% enhance in information of this behaviour.
Although 100% of individuals have been conscious of the necessity to maintain fish waste and meals scraps out of the water, our pre-surveys between August and October final yr discovered about one-third of vacationers nonetheless disposed of fish scraps into the water. After the intervention, the share of individuals doing this dropped to 4-8%.
Shifting the ‘she’ll be proper’ perspective
The excellent news is there’s very excessive consciousness of SharkSensible behaviours and most occasions, folks didn’t throw burley within the water, fish close to swimmers or swim in Cid Harbour.
Unfortunately, some folks continued to splash, swim alone and throw fish waste and meals scraps within the water. Changing these norms amongst swimmers and boaties will take time.
An perspective of “she’ll be proper” nonetheless exists amongst some water customers and this group would be the hardest to affect; it’s exhausting to shift attitudes about risks amongst folks with such a relaxed perspective to danger.
In the Whitsundays and wider Australia, we’re fortunate to have a number of the most unbelievable seashores, islands and reefs on this planet. Most of us are keen to take a small calculated danger to swim within the ocean. Shark chew incidents are extraordinarily uncommon in Australia however by making small adjustments, we will drive down the hazard even additional.
