Dr Rob Brander (AS, December 2012, p.38) used coronial data to find that ocean rips were responsible for 21 deaths per year from 2004–11. “This is likely to be an underestimate because there has to be a witness to an event who saw the person was caught in a rip, and then this information has to be included in the coronial report,” says Brander, a coastal geomorphologist at the University of NSW.

Surf Life Saving Australia notes that 121 people died in coastal waters last year. Many of these were a result of heart attacks or people being swept off rocks, but quite a few were from causes unknown with the possibility that a rip was responsible.

The figure was a record for the past 9 years, but Brander says the trend over the past 5 years has been towards fewer deaths from rips. “I’m wary of short-term data,” he says, “but I like to think this is because of better rip education”. Brander, who is sometimes known as Dr Rip, has played a big part in this, with a YouTube video about how to identify likely rips before swimming having had more than a million hits.

Brander recommends avoiding gaps in the surf where the water is green rather than white, saying these are usually rips. A way to remember this is that green is mean while white is alright.

It would take a large reduction to make rips less of a threat than other summer hazards. With access to...
