Slippery rocks, currents and daredevil jumpers make Australia’s waterways surprisingly deadly

But these idyllic scenes come with hidden risks. For instance, where the waterfall hits the pool, it creates turbulence and currents. If large volumes of water are falling, the pressure can be enough to push people underneath. Currents can also carry people underneath a rock ledge and trap them.

Adrenaline-seekers might jump off the lip of the waterfall. This is very risky, especially if you don’t know how deep the water is.

Droplets and mist from the falls mean the rocky sides are inevitably slippery and often covered in algae or moss.

Finally, there’s the popularity factor. The more inexperienced people who go, the higher the chance of something going wrong. Social media reels of influencers at beautiful locations encourage more people^[8] to seek out secluded waterfalls.

Are these deaths getting more common? We don’t know. That’s because deaths at waterfalls are rolled into statistics for river-related deaths. By one estimate^[9] 5% of drownings in inland water sources took place at waterfalls or swimming holes over the ten years to 2021.

We do know there’s been a surge^[10] in selfie deaths worldwide in recent years. Some of these deaths^[11] take place at waterfalls, usually when visitors jump the fence or make their way to the lip of the waterfall before slipping and dying. When you’re searching for the perfect selfie location, you’re not paying close attention to risks.

If you do get into trouble, help is often a long way away. Rescuers can take hours to arrive, while drowning happens very quickly. While popular beaches usually have lifeguards able to spring into action, waterfalls, waterholes and rivers do not.

How can we stay safe?

Waterfalls are some of the world’s great natural spectacles. The most famous attract millions of visitors each year, from Niagara Falls on the Canada-United States border to Victoria Falls between Zambia and Zimbabwe to Venezuela’s Angel Falls, the tallest uninterrupted waterfall. They are created^[13] when soft rock is washed away, or where a river meets a natural drop such as a cliff.

We’re drawn to these places, and that’s not going to change. So how can we visit safely?

Authorities have put up signs around many popular swimming spots, including waterfalls. These can be useful to indicate danger or prohibit an activity. But most people simply ignore them, according to^[14] a Queensland government spokesperson.

The most important thing is to proceed with caution. Just as you would check a new beach for signs of rip currents or dangerous waves, you should check waterfalls and waterholes for hidden dangers. Don’t assume picturesque places are safe because they’re pretty.

Familiarity matters too. Many people who have died at waterfalls have been visitors, whether from interstate or overseas^[15]. If you grew up near a waterfall or waterhole, you’re more likely to have learned about the dangers.

If you’ve checked the swimming hole, swimming should be reasonably safe. But it’s best to avoid going directly under the waterfall.

Climbing waterfalls is very dangerous. It might look fun, but slippery rocks can send you crashing to your doom, while turbulent water and hidden rocks under the surface can be lethal. The lip of a waterfall is extremely slippery and gravity is not on your side.

The lip of a waterfall is usually extremely slippery. This video shows a hiker in Hawaii slipping down a 15 metre waterfall. She survived.

Alcohol and waterfalls are a bad mix. Alcohol makes some people take more risks. Swim first, drink later.

Check the chance of rain before you go, and not only at the waterfall but upstream. Intense rain upstream can create flash floods surprisingly quickly, sweeping you off your feet^[16].

And if you’re in northern Australia, you need to do one more vital check – for crocodiles. Many popular waterfalls and swimming holes are seen to be safe because they are elevated or far from the sea. But crocs can pop up in unexpected places^[17].

Does this mean you should avoid waterways entirely? No. As Paul McCartney^[18] advised:

Don’t go jumping waterfalls

Please, keep to the lake

People who jump waterfalls

Sometimes can make mistakes.
