The shortfin mako, longfin mako and porbeagle sharks have widespread distributions in temperate and tropical waters of all the world’s oceans. Makos are bycatch and by-product species of pelagic longline and gillnet fisheries where they are taken for their meat and high-value fins. They are also highly-prized recreational species in many regions. Makos have low productivity, typical of sharks that do not mature until reaching a large size, producing few young and where individuals are unlikely to reproduce annually. Risk assessments both nationally and in the Atlantic concluded that mako sharks are at the highest risk of all pelagic sharks. These species are listed by the IUCN as Vulnerable globally and Critically Endangered in the Mediterranean. Significant population declines in the Mediterranean Sea and the North Atlantic resulted in these species being listed under Appendix II of the Convention on Migratory Species (CMS) in 2008 and concomitant listing under Australia’s EPBC Act in January 2010. This effectively meant that the target commercial or recreational fishing for these species was prohibited in Australian waters. In May 2010 the National Recreational Mako Shark Fishery - Management Forum identified the need for a study to identify and propose cost effective ways to fill key gaps in the collective knowledge of these species. In July 2010, after considerable debate, a legislative amendment was made to allow for the recreational fishing of mako and porbeagle sharks in Commonwealth areas despite the offence provisions under the EPBC Act. Commercial targeting of these species remains an offence, however, there are exemptions where they are taken as bycatch under accredited management plans. The Federal Environment Minister also directed DEWHA/SEWPaC to work with Fisheries Managers to provide a “more comprehensive information base on mako and porbeagle sharks for the future”. This project is a direct result of these needs.

In many states and regions around Australia there is a lack of current and reliable recreational fisheries data (e.g. participation rates, catch) that can be used in decision-making processes. Since the stock boundaries of some recreationally-important species can span several State and Federal jurisdictions, reliable stock-specific data is needed. The results of the last national recreational fishing survey undertaken in 2000-2001 are now considered outdated in many respects, or are of limited use for rarely-caught species and some fisheries or regions due to issues of scale.

Since the national survey, various recreational fishing surveys have been undertaken by State fisheries agencies to address their own specific management issues. These surveys have generally been telephone-diary approaches based on the National survey methodology. Additionally, community-based recreational fishing data collection have been undertaken at regional levels by community and recreational fishing groups. However, there has been a lack of coordination between agencies to report at a national level. Therefore, there is a need to assess the feasibility of aggregating data from these surveys to provide reliable up-to-date information at regional and national levels.
