[1] Four well-identified tropical cyclones over the past century have been responsible for depositing distinct units of predominantly quartzose sand and gravel to form the most seaward beach ridge at several locations along the wet tropical coast of northeast Queensland, Australia. These units deposited by tropical cyclones display a key sedimentary signature characterized by a sharp basal erosional contact, a coarser grain size than the underlying facies and a coarse-skewed trend toward the base. Coarse-skewed distributions with minimal change in mean grain size also characterize the upper levels of the high-energy deposited units at locations within the zone of maximum onshore winds during the tropical cyclone. These same coarse skew distributions are not apparent in sediments deposited at locations where predominantly offshore winds occurred during the cyclone, which in the case of northeast Australia is north of the eye-crossing location. These sedimentary signatures, along with the geochemical indicators and the degraded nature of the microfossil assemblages, have proven to be useful proxies to identify storm-deposited units within the study site and can also provide useful proxies in older beach ridges where advanced pedogenesis has obscured visual stratigraphic markers. As a consequence, more detailed long-term histories of storms and tropical cyclones can now be developed.

International and national representations of the beach perpetuate normative female concepts by maintaining dominant masculine myths, such as that of the heroic lifesaver and tanned sunbaker. Female experiences on the beach are traditionally associated with rhetorics of danger and peril, contrasted to the welcomed and protective gaze of the beach male. Conventional understandings of the gaze promote male surveillance of women, and although some resistance exists, the beach primarily remains a place to observe the female form. This article attempts to explore currents of resistance at the beach through a self-reflexive examination of Schoolies. Although the event is fixed within patriarchal codes and structures, small eddies of resistance exist amongst female participants in light of increasing awareness of masculine hegemony. The Australian beach remains a contested site of multiple constructs of gender and national identity. This article reveals the changing tides of resistance.

The Australian beach is now accepted as a significant part of Australian national culture and identity. However, Huntsman (2001) and Booth (2001) both believe that the beach is dying: “intellectuals have failed to apply to the beach the attention they have lavished on the bush…” (Huntsman 2001, 218). Yet the beach remains a prominent image in contemporary literature and film; authors such as Tim Winton and Robert Drewe frequently set their stories in and around the coast. Although initially considered a space of myth (Fiske, Hodge, and Turner 1987), Meaghan Morris labelled the beach as ‘ordinary’ (1998), and as recently as 2001 in the wake of the Sydney Olympic Games, Bonner, McKee, and Mackay termed the beach ‘tacky’ and ‘familiar’. The beach, it appears, defies an easy categorisation. In fact, I believe the beach is more than merely mythic or ordinary, or a combination of the two. Instead it is an imaginative space, seamlessly shifting its metaphorical meanings dependent on readings of the texts. My studies examine the beach through five common beach myths; this paper will explore the myth of the beach as an egalitarian space. Contemporary Australian national texts no longer conform to these mythical representations – (in fact, was the beach ever a space of equality?), instead creating new definitions for the beach space that continually shifts in meaning. Recent texts such as Tim Winton’s Breath (2008) and Stephen Orr’s Time’s Long Ruin (2010) lay a more complex metaphorical meaning upon the beach space. This paper will explore the beach as a space of egalitarianism in conjunction with recent Australian fiction and films in order to discover how the contemporary beach is represented.

The Centre for Subtropical Design has prepared this submission to assist the Gold Coast City Council to finalise a plan and detailed design guidelines for the Urban Plaza Zone of Surfers Paradise Foreshore Redevelopment Masterplan which will create a public open space ‘alive’ with the quality appropriate to a place which is both a local centre and an international destination. This review has been informed by the two over-arching values identified as characteristics of a subtropical place and people’s connection to it:  A sense of openness and permeability, and  Engagement with the natural environment. The existing qualities of the foreshore area proposed as the Urban Plaza Zone, reflect these subtropical place values, and are integral to the Surfers Paradise identity:  Seamless visual and spatial access to the beach and sea,  Permeable interface between beach and built zones provided by beach planting and shade to sand by Pandanus,  A shade zone mediating beach and linear promenade, road and commercial zones, enabling a variety of social and visual experiences, on soft and hard finishes, and  A lively, constantly moving shared road and pedestrian way catering for events and day to day activities with visual access to beach and shaded areas. The Centre for Subtropical Design commends the Gold Coast City Council on preparing a plan for a public open space that is a contemporary departure from the adhoc basis of development that has occurred, in that it will make this area more accessible. However, the proposed plan seems to be working too hard in terms of ‘program’. While providing an identifiable interruption in the linear extent of the Foreshore, the lack of continuity of design in terms of both hardscaping (such as perpendicular paving elements) and softscaping (such as tree selections) may contribute to a lack of definition for the entire Foreshore as a place that mediates, along its length, between sea and land. Providing a hard edge to a beach character of soft and planted transitional elements needs to balance the proposed visual and physical barrier with the need for perceived and actual easy access. The Surfers Paradise identity needs strengthening through attention to planting for shade, materials, particularly selection of paving colours, and stronger delineation of the linear nature of the Foreshore. The Urban Plaza zone is an appropriate interruption to the continuous planting, however the link from the commercial zone overtakes the public and beach zone. A more seamless transition from shop to sea, better integration of the roadway and pedestrian zone and improved physical transition from concrete to sand is recommended. Built form solutions must be robust and designed with the subtropical design principles and the Surfers Paradise identity as underpinning parameters for a lasting and memorable public open space.

The Australian beach is a significant element of our national identity. Since the majority of the population lives on the coastlines of the continent, the beach (rather than the Bush) plays an important role to many Australians. Yet the beach can also be a complex setting because of the often complicated concepts of ownership that surround it. ‘Flagging Spaces’ examines the layers of complexity surrounding textual representations of ownership of the beach space. In particular, this paper explores the Indigenous representation on the beach moving through to the role of multiculturalism on the beach space in the wake of the 2005 Cronulla riots, using specific textual examples such as Sacred Cows (Heiss 1996), Australia (dir. Baz Luhrmann 2008), Heaven (dir. Tracey Moffatt 1997), Radiance (dir. Rachel Perkins 1998), Butterfly Song (Jenkins 2005), and Bra Boys (dir. Sonny Abberton 2006).
