Guardians of the deep - rethinking shark nets for Kiama's waters

Kiama's pristine shores and idyllic scenery hides an ongoing debate that echoes across New South Wales. The issue at hand - whether to remove shark nets from our beaches - strikes at the heart of ocean conservation and the delicate balance between human safety and the thriving marine ecosystem. Amid this discourse, the insights of experts have surfaced, advocating for a shift towards ocean protection that safeguards both beachgoers and the magnificent creatures that inhabit our waters.



The current dialogue surrounding shark nets and their efficacy in safeguarding swimmers reveals a complex and nuanced challenge. In an effort to shed light on this issue, Professor Rob Brander and Dr. Amy Peden from the UNSW Beach Safety Research Group stand ready to share their invaluable expertise. With extensive experience in coastal processes and injury prevention, these experts emphasise that the true risks associated with ocean swimming extend beyond the shadows cast by sharks.


Prof. Brander, a distinguished beach safety researcher with over three decades of experience, unearths the pivotal role played by natural elements like rips and treacherous water conditions. His research delves into the intricate interplay between physical and social factors that contribute to beach hazards, all aimed at reducing incidents of drowning and injuries along our coasts.


Dr. Peden, an advocate for global drowning prevention, is committed to raising awareness about the comprehensive impact of drowning. In her own words, "While keeping swimmers safe from sharks is undoubtedly important, every year, significantly more people die or are rescued from drowning along the coast than are attacked or killed by sharks." Her extensive research reveals that enhancing public education and prevention efforts is a pivotal strategy for curbing ocean-related risks.



It's a startling revelation - one that invites us to broaden our understanding of ocean safety. While shark encounters naturally capture our attention, the grim reality is that rips and treacherous currents pose a far greater threat. Prof. Brander and Dr. Peden advocate for a paradigm shift, one that emphasises primary prevention strategies, such as swimming within the designated safe zones and recognizing the telltale signs of rips.


In a move that resonates deeply with our coastal community, Kiama introduced smart drum lines in 2017 as a response to these challenges. However, the wider debate surrounding shark nets persists across the coastline of New South Wales. It's a debate driven by compassion, science, and a desire to protect the intricate balance of marine life.


Shark nets and drum lines, often deemed as protective measures, have sparked a vigorous conversation about their efficacy and ethical implications. Rather than forming a barrier for beachgoers, these devices have been shown to fall short of their intended purpose, with their limited coverage barely extending half the depth of the water they are set in. Their impact on marine life, especially threatened and endangered species, presents a poignant concern. The ripple effect of these measures extends to non-targeted marine animals, including dolphins, turtles, and whales, inadvertently placing them in harm's way.



Sharks, often misunderstood, play a vital role in the ocean's delicate tapestry. They act as apex predators, maintaining a harmonious equilibrium within marine ecosystems. By curbing populations of weaker prey species, sharks foster healthier gene pools and contribute to the ocean's cleanliness.


The path to ocean protection is multifaceted. As coastal residents, we cherish the ocean's bounty for recreation, sustenance, and livelihoods. Sharks, those majestic guardians of the deep, play an indispensable role in maintaining the marine ecosystem's vitality. It's a symphony of life that extends beyond the picturesque waves crashing on our shores.


As the debate rages on, let's remember that preservation transcends human safety aloneā€”it encompasses the intricate web of life that flourishes beneath the ocean's surface. With experts like Brander and Peden guiding our understanding, let us forge a path that respects both human lives and the magnificent creatures that call our oceans home.
