IntroductionDrowning is a leading cause of unintentional death, especially for males. In Australian coastal waters, young male adults account for 25% of the burden of male drowning. This study aims to describe young male coastal drowning deaths and to examine the prevalence of risk factors, especially alcohol and drugs.MethodsCharacteristics of unintentional fatal drowning involving males (15–34 years) were compared with other adults (15 years and older). Data were sourced from the National Coronial Information System (Australia) and Surf Life Saving incident reports (2004/2005–2018/2019). Relative risk was calculated and χ2 tests of independence were performed (p<0.05). Blood alcohol and drug concentrations were analysed with permutational analyses of variance.ResultsYoung males drowned more while jumping (9.85 times), swimming/wading (1.41 times), at rock/cliff locations (1.42 times) and on public holidays (1.8 times). Young males drowned less while boating (0.81 times), scuba diving (2.08 times), offshore (1.56 times) or due to medical factors (3.7 times). Young males drowned more (1.68 times) after consuming illicit drugs (amphetamines 2.26 times; cannabis 2.25 times) and less with prescription drugs (benzodiazepines 2.6 times; opiates 4.1 times; antidepressants 7.7 times). Blood serum concentrations of cannabis were higher in young males, while amphetamine and alcohol were lower.DiscussionUnsafe behaviours alongside certain activities or locations create deadly combinations of risk factors. A relationship between age, activity, attitude and affluence is proposed, where young males drown more in affordable activities with fewer regulations. Our results support multilevel strategies (spanning life stages) to reduce young male coastal drowning.

An issue of growing importance within the field of drowning prevention is the undertaking of aquatic rescues by bystanders, who sometimes drown in the process. The main objectives of this study were to describe characteristics of bystanders making rescues in different Australian aquatic environments, identify the role of prior water safety training in conducting bystander rescues and provide insights into future public education strategies relating to bystander rescue scenarios. An online survey was disseminated via various social media platforms in 2017 and gathered a total of 243 complete responses. The majority of bystander rescues described took place in coastal waterways (76.5%; n = 186), particularly beaches (n = 67), followed by pools (17.3%; n = 42) and inland waterways (6.2%; n = 15). The majority of respondents were males (64.2%; n = 156) who rescued on average approximately twice as many people in their lifetime (6.5) than female respondents (3.6). Most rescues occurred more than 1 km from lifeguard/lifesaver services (67%; n = 163), but in the presence of others (94.2%; n = 229). The majority of bystander rescuers had water safety training (65.8%; n = 160), self-rated as strong swimmers (68.3%; n = 166), conducted the rescue without help from others (60%; n = 146), did not use a flotation device to assist (63%; n = 153), but were confident in their ability to make the rescue (76.5%; n = 186). However, most considered the situation to be very serious (58%; n = 141) and felt they had saved a life (70.1%; n = 172). With the exception of pools, most bystanders rescued strangers (76.1%; n = 185).While Australia clearly benefits from having a strong water safety culture, there is no clear consensus on the most appropriate actions bystanders should take when confronted with a potential aquatic rescue scenario. In particular, more research is needed to gather information regarding bystander rescues undertaken by those without prior water safety training.

Bystanders who drown during a rescue attempt in aquatic waterways are becoming an increasingly important issue within drowning prevention. In the Australian context, the majority of these incidents occur in coastal water ways. This study documents and characterizes bystander rescuer fatalities within Australian coastal waterways that occurred between 1 July 2004 and 30 June 2019 in order to provide suggestions for future public safety interventions involving bystander rescuers. Data was sourced through Surf Life Saving Australia’s (SLSA) Coastal Fatality Database, which collates information from multiple sources. Sixty-seven bystander rescuer fatalities in coastal waterways were reported during the 15-year period, an average of 4.5 per year, which is a significant proportion of the five fatalities previously reported across all Australian waterways. The majority of coastal bystander rescuer fatality incidents occurred in the state of New South Wales (49%), at beaches (64%), in regional or remote areas (71%), more than 1 km from the nearest lifesaving service (78%), during summer (45%), in the afternoon (72%), in the presence of rip currents (73%), and did not involve the use of flotation devices to assist rescue (97%). The majority of coastal bystander rescuer victims were Australian residents (88%) born in Australia/Oceania (68%), males (81%), aged between 30–44 years old (36%), visitors to the location (55%), either family (69%) or friends (15%) of the rescuee(s), and were attempting to rescue someone younger than 18 years old (64%). Our results suggest future safety intervention approaches should target males, parents and carers visiting beach locations in regional locations during holiday times and should focus on the importance of flotation devices when enacting a rescue and further educating visitors about the rip current hazard. Future research should examine the psychology of bystander rescue situations and evaluate the effectiveness of different safety intervention approaches.

Natural hazards combined with the COVID-19 pandemic have had significant global impacts to the community and the environment. This study explores the impact of the Australian 2019/20 bushfires followed by the COVID-19 pandemic on unintentional coastal drowning fatalities. Fatality data were collated using triangulation methodology. Percentage change in coastal drowning fatalities between 2019/20 financial year (FY) and the 15FY annual average (2004/5–2018/19) were calculated for the dominant bushfire period (August 2019–February 2020 inclusive) and COVID-19 restrictions in place for 2019/20FY (March–June 2020 inclusive). Relative risk (RR; with 95% confidence intervals [CI]) of coastal drowning was calculated against the average for overall, bushfire and COVID-19 periods, using coastal participation data as the denominator, weighted for the predicted decrease in the use of outdoor coastal areas due to these widespread events. Coastal drowning fatalities increased in 2019/20FY by 9% overall (bushfires: 6%; COVID-19: 9%). Swimming/wading drowning fatalities increased during the bushfire period (RR = 2.02; 95% CI: 1.13–3.63), while boating and personal watercraft (PWC)-related fatalities increased during both the bushfire (RR = 2.92; 95% CI: 1.41–6.05) and COVID-19 period (RR = 3.86; 95% CI: 1.64–9.11). Rock fishing fatalities also increased across both the bushfire (RR = 4.19; 95% CI: 1.45–12.07; p = 0.008) and COVID-19 (RR = 3.8;95% CI: 1.24–11.62; p = 0.027) periods. Findings indicate the activity patterns leading to coastal drowning fatalities changed despite significant public health events impacting freedom of movement and thus opportunity for coastal participation. Understanding, and preparing for, the impacts of natural hazards on drowning risk is vital for future preventive efforts.
