Seven percent of river users legally drunk say researchers


New research reveals about as many as one-in-six people who swim in rivers is under the influence of alcohol, and nearly half of those swimmers are above the legal alcohol limit for driving.

A study conducted by Royal Live Saving- Australia and James Cook University surveyed locals and tourists at four river locations - Alligator Creek in Townsville, the Murrumbidgee River in Wagga Wagga, the Murray River at Albury, and the Hawkesbury River in Western Sydney.

Researchers used a breathalyser to gauge if people were swimming under the influence of alcohol. A total of 684 people were surveyed and breathalysed across 16 days at the four research sites.

Principle investigator Amy Peden is the National Manager of Research and Policy at Royal Life Saving – Australia, and a PhD candidate at JCU.

She said the study found 16 percent of swimmers recorded a positive blood alcohol content (BAC) and seven percent were over the legal driving limit, recording a BAC 0.05 or higher.

Of those who had been drinking, the average BAC recorded was 0.07, with one swimmer recording a BAC of 0.334 (six and a half times the legal limit for driving a motor vehicle).

Despite males being overrepresented in river drownings, the research identified similar numbers of males and females drinking alcohol at the rivers.

As part of the study, researchers collected data on the Australia Day holiday weekend and found the average BAC reading of those who had been drinking on the public holiday was 0.110 (more than double the upper legal limit).

“Alcohol is known to increase your risk of drowning and that’s especially true at rivers around the country. The average BAC of an adult who has been drinking and unintentionally drowned in an Australian river is 0.20, or four times the legal limit. This research will help us to target drowning prevention strategies to those most at risk,” said Ms Peden.

“We now have a better understanding of the type of person who drinks alcohol at the river. That person visits the river in the afternoon, with friends and on warm days. They are more likely to be frequent river users who spend longer in the water than those who weren’t drinking,” she said.

At Alligator Creek in Townsville, researchers surveyed and breathalysed 122 people. Most visited the river to walk, have a picnic or to swim (usually in deep water). Just 42% reported having a current CPR qualification. Almost half (47%) said they sometimes or always drank alcohol at the river and 4% were above the legal limit when breathalysed.

The highest BAC recorded by researchers at Alligator Creek was 0.240 (almost 5 times the legal limit).

Alligator Creek was chosen as a research site due to its popularity as a location for Townsville residents to cool off. There has been one fatal drowning at the swimming spot in the past 15 years.

This world-first research is supported by funding from the Australian Government through Royal Life Saving’s inland waterways drowning prevention program Respect the River.

“This program is about raising awareness of drowning risk factors and equipping everyone with the skills to safely enjoy our beautiful rivers, creeks and streams,” said Justin Scarr, CEO, Royal Life Saving.

Rivers are the leading location for drowning in Australia with an average of 74 drowning deaths per year.

Royal Life Saving - Australia is releasing these interim findings to remind people that drowning can occur all year round, with 40% of the 1,103 river drowning deaths in the past 15 years occurring in Autumn and Winter.

Along with a message reminding river users to avoid alcohol around water, the Respect the River program highlights the importance of wearing a lifejacket, never swimming alone, and learning how to save a life (such as through a CPR course).

The full findings of the research will be published in academic journals over the coming months.
