Australia is seeing a clear increase in shark-related incidents, which has led to a review of marine safety rules and environmental management strategies.

澳洲目前顯見與鯊魚相關的事故增加，導致海洋安全規則與環境管理策略正被重新審視。

Data shows a long-term rise in unprovoked shark encounters. Records indicate that incidents have increased from an average of 3.1 per year in the 1950s to 21 per decade today, while annual deaths have risen from 1.7 to 3.8. This trend is partly caused by population growth and better wetsuit technology, which allows people to stay in the water longer. Furthermore, environmental changes are playing a role; for example, warmer ocean temperatures have brought more bull and tiger sharks to areas like Sydney. Additionally, the recovery of seal and whale populations has provided more food for top predators, which may increase their curiosity toward humans.

數據顯示，長期以來非挑釁性的鯊魚接觸次數有所上升。記錄指出，事故次數從1950年代平均每年3.1次，增加至如今每十年21次，而每年死亡人數則從1.7人上升至3.8人。這一趨勢部分是由於人口增長及潛水衣技術進步，使人們能長時間留在水中。此外，環境變化也發揮了作用；例如，海水溫度升高使更多公牛鯊與虎鯊進入如悉尼等區域。此外，海豹與鯨魚族群的恢復為頂端掠食者提供了更多食物，這可能會增加牠們對人類的好奇心。

Opinions on how to reduce these risks remain divided. Some people support the use of shark nets, whereas ecologists like Professor Corey Bradshaw argue that these are harmful to the environment and do not actually work. Instead, experts suggest that using drones, electronic tagging, and listening stations are more effective ways to reduce risk in real-time. Moreover, experts dismiss the idea of culling sharks because these animals migrate over large distances. Researchers also note that people often feel more afraid because they have little control in the ocean, even though shark attacks are statistically rare compared to other dangers, such as drowning.

關於如何降低這些風險，意見仍有分歧。有些人支持使用鯊魚網，而像 Corey Bradshaw 教授這樣的生態學家則認為，這些網對環境有害且實際上並無效果。相反，專家建議使用無人機、電子標記與監聽站，是更有效的即時降低風險方式。此外，專家否認屠殺鯊魚的想法，因為這些動物會進行長距離遷徙。研究人員也指出，儘管與其他危險（如溺水）相比，鯊魚攻擊在統計上極其罕見，但由於人們在海洋中缺乏掌控感，因此往往感到更恐懼。

To stay safe, behavioral guidelines suggest minimizing movement in the water. Marine consultants emphasize that keeping eye contact with a shark and avoiding sudden movements can reduce the chance of an attack. Consequently, swimmers are encouraged to be aware of high-risk factors, such as the presence of diving birds, river mouths after heavy rain, or the migration of small fish like mullet.

為了確保安全，行為指南建議在水中盡量減少移動。海洋顧問強調，與鯊魚保持眼神接觸並避免突然動作，可以降低被攻擊的機會。因此，泳客被鼓勵留意高風險因素，例如潛水鳥的出現、大雨後的河口，或如鯈魚等小魚的遷徙。

In summary, shark encounters are increasing due to a mix of environmental changes and more human activity in the ocean, while experts continue to debate the best ways to manage these risks.

總結來說，由於環境變化與人類海洋活動增加，鯊魚接觸次數正在上升，而專家們仍持續爭論管理這些風險的最佳方式。
