🦈Four shark attacks have now been recorded off NSW beaches in 48 hours, with authorities closing more than 20 beaches. A man surfing at Point Plomer is reported to have only minor injuries after a shark bit through his board, following a series of attacks that left a man and a 12-year-old boy in critical condition. An 11 year old also had his board bitten by a shark at Dee Why.
In response to the attacks, Dr Rebecca Olive from RMIT University says, "Shark encounters are an unavoidable possibility of using oceans for leisure and recreation."
But what can we do to avoid future incidences?
Professor Culum Brown from Macquarie University explains that we can "First, avoid swimming on your own - this is a general rule for safe swimming, but it equally applies to sharks. If someone gets bitten, you need to seek help as fast as possible.
Second, avoid swimming at dawn and dusk - this tends to be a time when sharks are more active.
Third, don't swim after heavy rainfall, especially in and around estuaries. Sharks, especially bulls, are drawn to freshwater flushes to feed on fish and dead animals as they drift down from rivers. Analysis of bull shark catches close to shore always shows an effect of rainfall.
Fourth, don't swim in murky water (also associated with high rainfall). Sharks' vision for finding prey will be impeded, and they will be attracted to disturbances in the water. They are more likely to accidentally bite a person, thinking it is prey (sharks do not eat people)."
Professor Jodie Rummer from James Cook University says that it's important to note "First and foremost, any injury in the ocean is confronting, and it is important to approach this conversation with care and respect for those affected by these very serious shark-human interactions. It is also important to frame these as shark-human interactions rather than deliberate attacks. Sharks do not target people."
