The objective was to describe the relationship between epidemiological and biomechanical factors in the causal pathway of inflatable rescue boat (IRB)-related injuries in Australian surf lifesavers; to develop epidemiological and biomechanical methodologies and measurement instruments that identify and measure the risk factors, for use in future epidemiological studies. Epidemiological and biomechanical models of injury causation were combined. Host, agent and environmental factors that influenced total available force for transfer to host were specified. Measurement instruments for each of the specified risk factors were developed. Instruments were piloted in a volunteer sample of surf lifesavers. Participant characteristics were recorded using demographic questionnaires; IRB operating techniques were recorded using a custom-made on-board camera (Grand RF-Guard) and images of operating techniques were coded by two independent observers. Ground reaction forces transmitted to the host through the lifesaver's feet at the time of wave impact were measured using a custom-built piezoelectric force platform. The demographic questionnaire was found practical; the on-board camera functioned successfully within the target environment. Agreement between independent coders of IRB operating technique images was significant (p < 0.001) with Kappa values ranging from 0.5 to 0.7. Biomechanical instruments performed successfully in the target environment. Peak biomechanical forces were 415.6N (left foot) and 252.9N (right foot). This study defines the relationship between epidemiological and biomechanical factors in modifying the risk of IRB-related injury in a population of surf lifesavers. Preliminary feasibility of combining epidemiological and biomechanical information has been demonstrated. Further testing of the proposed model and measurement instruments is required.

The Inflatable Rescue Boat (IRB) is arguably the most effective rescue tool used by the Australian surf lifesavers. The exceptional features of high mobility and rapid response have enabled it to become an icon on Australia's popular beaches. However, the IRB's extensive use within an environment that is as rugged as it is spectacular, has led it to become a danger to those who risk their lives to save others. Epidemiological research revealed lower limb injuries to be predominant, particularly the right leg. The common types of injuries were fractures and dislocations, as well as muscle or ligament strains and tears. The concern expressed by Surf Life Saving Queensland (SLSQ) and Surf Life Saving Australia (SLSA) led to a biomechanical investigation into this unique and relatively unresearched field. The aim of the research was to identify the causes of injury and propose processes that may reduce the instances and severity of injury to surf lifesavers during IRB operation. Following a review of related research, a design analysis of the craft was undertaken as an introduction to the craft, its design and uses. The mechanical characteristics of the vessel were then evaluated and the accelerations applied to the crew in the IRB were established through field tests. The data were then combined and modelled in the 3-D mathematical modelling and simulation package, MADYMO. A tool was created to compare various scenarios of boat design and methods of operation to determine possible mechanisms to reduce injuries. The results of this study showed that under simulated wave loading the boats flex around a pivot point determined by the position of the hinge in the floorboard. It was also found that the accelerations experienced by the crew exhibited similar characteristics to road vehicle accidents. Staged simulations indicated the attributes of an optimum foam in terms of thickness and density. Likewise, modelling of the boat and crew produced simulations that predicted realistic crew response to tested variables. Unfortunately, the observed lack of adherence to the SLSA footstrap Standard has impeded successful epidemiological and modelling outcomes. If uniformity of boat setup can be assured then epidemiological studies will be able to highlight the influence of implementing changes to the boat design. In conclusion, the research provided a tool to successfully link the epidemiology and injury diagnosis to the mechanical engineering design through the use of biomechanics. This was a novel application of the mathematical modelling software MADYMO. Other craft can also be investigated in this manner to provide solutions to the problem identified and therefore reduce risk of injury for the operators.

The first practice-led research project 'Heroes of the Club', through collaboration with business and community, involved portraying the stories on canvas of heroes of the Australian Surf Life Saving movement. The second project 'Crossing the intersection… art and life' researched a post-modernist approach to a fusion of the aesthetics of Abstract Expressionism and Pop Art. This study resulted in a body of work 'Long Playing' which sought to harmoniously reconcile two apparent polarities of style and context between high and low art characteristics, through personal narrative and with reference to artistic tradition.

Since the publication of Fiske, Hodge and Turner’s Myths of Oz: Reading Australian Popular Culture (1987), Australian Cultural Studies has turned to the beach as a primary site for examining national identity and the myths of Australian culture. In the text the beach is read as a liminal site between ‘culture’ and ‘nature’, represented respectively by lifesaver and surfer. The meanings of anti-authoritarianism attached to the surfer are significant to the reading. And yet Fiske, Hodge and Turner also locate a heritage of authoritarianism, discipline and civic duty in the figure of the lifesaver:
'Lifesavers have drills, march-pasts and patrol squads, while exercising a conservative pastoral interest in their members’ moral health. They are agents of social control. Further, they see themselves as servants of the community, sacrificing their weekends for others—a tradition of sacrifice dear to a nation which twice voted no to conscription in the Great War.' (Fiske et al. 1987, 64–65)
The last sentence distils the bifocal meanings not only of the ‘culture’ of the beach but of Australian cultural identity more broadly, framed by contested norms of civic participation and moral values. This binary frame has been a productive starting point for analyses of national identity in Australian Cultural Studies since the 1980s. These have dropped off the radar in recent years owing to a shift away from the national field and the privileging of a transnational cultural agenda. And yet recent events in Australian politics and culture have unexpectedly re-centred national identity as an urgent issue for Cultural Studies, particularly in its use as a form of exclusion to targeted populations within the national community.
In light of these developments this article revisits Myths of Oz and its construction of surfer and lifesaver c.1987 to focus on the reordering and re-assemblage of these figures on Sydney’s beaches 20 years on. It also acknowledges that this is a process which cannot be understood in isolation from broader shifts in Australian political culture, and particularly the current obsession with national ‘values’ hinging on a strategic shift away from multicultural policies and the redefinition of the ‘fringe’ as an ethnic position.
Reflecting on these issues, this article locates a slippage between the binary framing of the surfer and lifesaver in Myths of Oz and their complex ‘relationality’ on the beach today. Specifically, it examines how the surfer has recently become co-opted into the Australian mainstream and imbued with a form of ‘governmental belonging’ (Hage 1998) once attributed to the lifesaver alone. This slippage has been enabled by the overlap betweenlocal surfie cultures and exclusivist national cultures assembled by State and federal governments; particularly as both draw upon a normative frame that opposes the meanings of white belonging to Muslim groupings within the nation.
