We present a national social and economic benchmark for the Australian Marine Parks (AMPs), focussing on four key groups: the general public, recreational fishers, non-extractive recreational users, and charter operators. Establishing this benchmark involved conducting four integrated surveys nationally reaching approximately 4,000 respondents. The AMP benchmarks established here are amongst the most comprehensive globally in terms of the spatial extent and stakeholder groups considered. Overall, the surveys highlight the substantial values associated with the AMPs, and generally positive perceptions and attitudes towards the parks. The surveys also highlight potential areas for survey improvement, and data was collected to help address these (e.g. preferred modes of contact). The information is intended to inform management of the AMPs in ways that align with the preferences of stakeholders and the broader community.
