Methodology 2011 National Coastal Safety Report
INTRODUCTION
METHODOLOGY
For more than 100 years, Australians and visitors to Australia have been drawn to our coastline. With an estimated 100 million beach visitations each year, the task of ensuring the safety of everyone who visits Australia’s 11,600+ beaches and approximately 36,000 kilometres of coastline is an extremely challenging one, and one that Surf Life Saving (SLS) is dedicated to.
The 2010-11 National Coastal Safety Report contains information on all confirmed coastal drowning deaths for the period of 1 July 2010 to 30 June 2011. This information is correct as of 31 July 2011.
Since 1907, when a group of surf life saving clubs on Sydney’s beaches first emerged, the network of services protecting our coastline has grown rapidly. Today, volunteer surf lifesavers, SLS and councilemployed lifeguards, rescue helicopters, rescue power craft, surveillance systems and radio control and coordination centres all work together to ensure that our beaches are the safest in the world. This collaborative approach to coastal safety is essential in preventing drowning along our coastline. Despite this extensive network of services, coastal drowning deaths are still at unacceptable levels. In 2010-2011, there were 61 coastal drowning deaths* in Australia, and while this figure is down on last year’s 84 coastal drowning deaths and the seven-year average of 89, it still shows that there is significant work ahead of us – every life lost is one life too many. SLSA produces the National Coastal Safety Report to provide a detailed annual summary of coastal drowning deaths in Australia. In 2010-11 the report has adopted a more rigorous methodology to ensure the data provided is as thorough as possible and better assists all coastal safety service providers with evidence-based decision making. I commend this report to you as part of the ongoing process to reduce coastal drowning deaths. Brett Williamson OAM Chief Executive Officer Surf Life Saving Australia

All care is taken to ensure the statistical information included in this report is correct. However, pending the outcome of ongoing coronial investigations, this data may be amended. A validation of drowning data has recently been completed by Surf Life Saving Australia (SLSA) using the National Coroners Information System (NCIS). This process included a review of definitions, with new definitions for coastal drowning death, inland drowning death, ocean drowning death, and undetermined presented in the glossary of terms on page 24. A search query was performed for all deaths due to drowning between 1 July 2010 to 30 June 2011 and the new definitions were applied to generate this report.
Data Sources SLSA collects incident data from our own SurfGuard Incident Report Database (IRD), the NCIS and by monitoring media reports for drowning incidents. The information is verified with the assistance of each state Surf Life Saving centre and compiled for analysis by SLSA’s Lifesaving and Research Departments. The following information is recorded for each drowning incident: state; date; drowning location; GPS coordinates; time; age; gender; incident type; activity information; whether the incident was work related; entered into IRD; IRD number; NCIS case number; whether the case is open/closed; whether the case was reported by the state; the original source of information; drowning location suburb; local government area; postcode; associated SLS club; month; day; season; quarter; victim’s name; address; residence country; residence distance to coastline; residence distance to drowning location; victim’s birth country; nationality; time in Australia; main language; additional activity information; the victim’s experience in the activity; whether the incident was rip current related; detailed description of the incident; details relating to alcohol, drugs, or health conditions; weather conditions; wind conditions; sea conditions/ wave size; wave type; water surface; temperature; tides; location to a lifeguarding service; whether the location was patrolled at the time; personnel who
The following variables are used to match drowning cases from more than one data source: incident date; location; age; gender; and incident description. The NCIS is considered the ‘gold standard’ when there is a discrepancy in the detail collected from different data sources. Annual drowning rates are calculated using the Australian Bureau of Statistics (ABS) population statistics for each year and individual states. The rates are based on 100,000 members of the population. ABS numbers for the June quarter of each year or the latest data available for the current year is used for calculations.
Verification Process The original drowning data that had been published in SLSA reports from 2004-2010 has been reviewed to ensure the validity of the data. Each case was analysed to ensure that the descriptions as ‘coastal drowning death’, ‘coastal death’, ‘inland drowning death’, ‘ocean drowning death’, and ‘undetermined’ meet both our current definitions and the NCIS information available. Deaths that are reported as ‘unintentional’, ‘unknown intent’ and ‘unlikely to know intent’ are included. Deaths are excluded if they are reported as ‘intentional deaths’, they are inland/ocean locations or drowning is not the primary cause of death. The new list is compared to the original data and any necessary inclusions are made. All details are also matched with the NCIS reports. When incidents on our database were not found on NCIS, we liaised with NCIS personnel for help. Cases with detailed IRD and media reports are investigated and included whether the NCIS case number is found or not.
NCIS cases we can modify undetermined cases, those with unknown intent, and those where the cause of death is not drowning. Details will not be provided in this report if incidents occur where there are less than 5 drownings per state to protect the privacy of the individuals.
What is a coastal drowning death? SLSA defines a coastal drowning death as a fatality arising from the process of respiratory impairment from submersion/immersion in the foreshore, seabed, coastal water, and air space above a large body of water (harbour/bay/inlet), including areas up to 2NM offshore and of which the landward boundary is the line of mean high water, except that where that line crosses a river/inlet, the landward boundary at that point shall be the point upstream that is calculated by multiplying the width of the river/inlet mouth by 5. These unambiguous coastal/inland boundaries have been adopted from New Zealand’s Resource Management Amendment Act 1991 (NZ Ministry for the Environment, 1991).

Changes from previous reports Activity categories have been changed to include beach activities, separate diving and snorkelling, and to specify rock fishing incidents. The verification process has modified previously reported totals as illustrated below:

Over years of investigation as part of the NCIS process, some cases are amended prior to their closure, resulting in changes to the classification of cases in our datasets. Therefore, the number of coastal drowning deaths published in this report may be different from annual totals previously reported. In an effort to produce a timely report on our current year’s data we acknowledge that these figures will change. Each year, the changes that occur in the previous year’s report will be made transparent. The data in this current report are not the final figures as 51 coastal drowning deaths reported remain open cases. Once closure occurs to

Geoscience Australia recognises the following locations as Remote Offshore Territories (ROTs): Christmas Island, Cocos (Keeling) Islands, Coral Sea Islands, Norfolk Island, Heard Island and McDonald Islands, and the Australian Antarctic Territories. Coastal Drowning Deaths in ROTs will be listed in their own separate category in this, and future issues of the National Coastal Safety Report. Media reports describe a refugee boat crash on Christmas Island, 5 December 2010, that resulted in up to 50 deaths. This is classified as a disaster incident because ten or more people were suddenly killed. Please see the definition on page 24. There are only 20 of these cases closed within the NCIS at the time of this publication. All of these cases have been closed with a cause of death (COD) as “Body not found-missing person”. We don’t include these as drowning deaths. We will describe the other possible 30 individuals as ‘undetermined’ until coroner reports are produced. We will update this data in future reports as we will with other open cases that do not have a COD listed. 22

Seven year trend of coastal drowning deaths Figure 54
The Australian Water Safety Council (AWSC) launched the Australian Water Safety Strategy in October 2008. This strategy includes an aim to achieve a 50% reduction in drowning deaths by the year 2020 (AWSC, 2008).
2010-11
to 2006-07. The average rate of coastal drowning deaths during the same period was 0.48 per 100,000 population. The last three years (2008-09 to 2010-11) have been analysed resulting in a current average rate of 0.36. This is a 25% reduction in the rate of coastal drowning deaths. SLSA strives to continue this trend to meet and hopefully surpass the goal of a 50% reduction by 2020.
The AWSC calculated a baseline average from drowning death data collected from 2004-05

Individuals of foreign ethnicity coastal drowning deaths Figure 55
In 2010-11, 21 coastal drowning victims were of a foreign ethnicity. This represents 34.4% of all coastal drowning deaths this year. The average percentage of coastal drowning deaths has not changed much over time. The baseline three year (2004-07) average is 35.0%, the current three year (2008-11) average is 34.9%. When the last seven years of data are averaged, individuals of foreign ethnicity make up 35.2% of coastal drowning deaths. This over-representation of persons of a foreign ethnicity in our drowning data remains consistent and will continue to be an intervention priority.

An understanding of why people drown is significant when developing drowning prevention strategies. Four key factors have been identified that may lead to accidental drowning, known as the ‘Drowning Chain’. Any of these factors alone, or a combination, could lead to death by drowning (George, 2011).
Drowning chain and drowning prevention strategies Table 3
Drowning Chain
Drowning Prevention Strategies
Lack of knowledge, disregard or misjudgement of a hazard
Education and information
Uninformed, unprotected or unrestricted access to a hazard

Lack of supervision or surveillance
Provision of supervision
Inability to cope once in difficulty
