A Summer of Tragedy: Why Ocean Education Matters More Than Ever
The recent series of shark encounters in Sydney, including one tragic fatality, is a sobering reminder of why education about the ocean and its inhabitants is so important. While these events are devastating, they also highlight a crucial truth: understanding marine environments, shark behaviour, and safe swimming practices can significantly reduce the risk of dangerous encounters.
If more people had a basic understanding of shark movement patterns, feeding behaviour, and how weather events affect ocean conditions, many of these incidents may have been avoided.
How Heavy Rain Changes Shark Behaviour
Over summer, Sydney experienced substantial rainfall. This causes large volumes of freshwater, along with pollution and runoff, to flow into rivers, canals, and bays. Bull sharks, which often inhabit these areas, are forced out of their usual environments in search of cleaner, saltier water.
As a result, they move along the coastline and closer to popular recreational areas such as Sydney’s Northern Beaches.
However, even coastal water after heavy rain is often murky and dirty. In low-visibility conditions, sharks cannot rely on sight to hunt. Instead, they detect vibrations in the water. Erratic splashing or surface movement can feel like injured fish or prey, causing sharks to investigate. They do this with their mouths, which can result in catastrophic injuries to humans.
It’s important to understand that sharks – including bull sharks – do not consider humans to be food. These encounters are cases of mistaken identity.
Safer Swimming Starts With Knowledge – The Message is Simple & Clear:
Avoid swimming in murky or dirty water, especially after heavy rain
Don’t swim at dawn or dusk, when visibility is low and sharks are more actively feeding
Pay attention to water conditions, warnings, and local advice
If more people were armed with this knowledge, safer swimming practices would be far more widely followed – and the risk of incidents would be greatly reduced.
Education, Not Fear, Is the Answer
We must learn to live with the environment and all that is in it, not try to change it to suit ourselves. Culling sharks is not the answer to making the ocean safer.
Education is.
By teaching children and adults how ocean ecosystems work, how animals behave, and how to safely enjoy our beaches, we empower people to make smarter, safer choices – and protect both humans and marine life.
At Ocean Life Education, this is exactly what we believe in: building understanding, respect, and knowledge so we can all enjoy the ocean more safely and responsibly.
