Brisbane’s Courier-Mail newspaper ran a fantastic story a couple of years ago about a couple left at sea behind by their tour boat, after going scuba diving. The story suggested American diver Allyson Dalton and her British partner Richard Neely ignored advice when they ventured away from a lagoon where the tour boat was anchored. But the focus was on how Neely and Dalton survived by treading water for 19 hours at Paradise Reef, part of Queensland’s Great Barrier Reef, not so much (yet) on how fortunate they were not to be attacked by sharks. It would not be long, however, before that old journalistic maxim that implores practitioners to ‘question every assertion, doubt every claim’ shaped the reportage into an extended narrative about chequebook journalism, credibility, and culpability.

The scuba dive rescue story analysis presented here reflects contemporary journalism’s role in the formation of ideas about cultural value and character, and in more complex determinations of who gets a participatory stake in the formation of national narratives. As such, the article concludes with some signposts toward a critical approach to journalism-centred studies of culture in Australia.

In recent years there has been an increase in community-based monitoring programmes developed and implemented worldwide. This paper describes how the data collected from such a programme could be integrated into a Geographic Information System (GIS) to create temperate subtidal marine habitat maps. A differential Global Positioning System was utilized to accurately record the location of the trained community-based SCUBA diver data. These georeferenced data sets were then used to classify benthic habitats using an aerial photograph and digitizing techniques. This study demonstrated that trained community-based volunteers can collect data that can be utilized within a GIS to create reliable and cost-effective maps of shallow temperate subtidal rocky reef systems.

In October 2003, US citizen Christina Thomas died while scuba diving on Queensland’s Great Barrier Reef. Following over five years of delays, her husband David Watson accepted a plea bargain to which he pleaded guilty to manslaughter on the basis of criminal negligence. Watson was initially sentenced to four and a half years imprisonment, suspended after 12 months, however this was later increased on appeal to suspension after 18 months. Using Watson as a framework for analysis, this article examines some of the limitations of an inefficient justice system, with a particular focus on the private nature of the plea bargaining process, and the potentially favourable representations and sentencing of men who kill a female intimate partner. The authors argue that the need to respond to court inefficiency and under-resourcing in the criminal courts creates pressures that can result in a desire for increased efficiency being prioritised above other justice concerns, and this allows for existing flaws within the operation of the criminal justice system to be exacerbated, and excused.

Shifting baselines describes the phenomenon where long-term changes to an environment go unrecognized because what is perceived as natural shifts with succeeding generations of scientists and other observers. This is a particular problem for the oceans because we are rarely able to directly observe the consequences of human activities. In the absence of data to track these consequences, a common assumption has been that the communities we observe today using SCUBA or other technology, are similar to the communities that existed 10, 100, or even 1000 years ago. Research is increasingly demonstrating this is not the case. Instead, marine ecosystems may have been vastly different in the past, and we have succumbed to the shifting baselines syndrome. This has significant implications for scientific study, management, and for human communities more broadly. We discuss these implications, and how we might address the shifting baseline syndrome in the oceans to confront its repercussions. In a world where environmental degradation is accelerating, doing so is critical to avoid further ratcheting down of our expectations of ecosystem health and productivity, and to ensure that we have the information necessary to implement appropriate recovery and management goals.
