Regarding the shark barrier, what information is available on marine life entangled and killed in it? And what use is it in winter?

No marine life has been tangled in or injured by the barrier. It is made of plastic and covers 15,000 square metres. The barrier has shown that it actually provides additional habitat for a range of marine creatures.

Many people still swim in the barrier in winter, particularly those who do triathlons. The fish still congregate and use the structure too.
