This record provides an overview of the NESP Marine and Coastal Hub project "Evaluation of recreational fishing behaviour, use, values and motivations that relate to compliance". No data outputs were generated by this project. -------------------- Recreational fishing is an important leisure activity in Australia that delivers important social and economic benefits to the community. As the largest and most widely dispersed natural resource-based recreational activity in the country, it is subject to management strategies including bag limits, quotas, and no-take zones. Given the prohibitive cost of deploying compliance officers to monitor Australia’s vast marine estate, strategies are needed to encourage voluntary compliance from fishers. This project explored behavioural interventions to promote self-compliance among recreational fishers, focusing on no-take zones within the Great Barrier Reef Marine Park and two Commonwealth parks off Western Australia (Geographe and Two Rocks). The research distributed more than 800 online surveys, followed up by focus groups and analysis to examine how demographics, motivations and fishing patterns influence fishers' intentions to comply with zoning rules. Survey insights were used to pilot a new targeted approach to awareness campaigns. Using behavioural segmentation, the project tailored messaging to specific audience types and tested these via GBRMPA social media channels. The project also examined perceptions of compliance visibility and found fishers were more likely to comply when uniformed officers were present and engaged directly at ramps or on water. The project outcomes provide a foundation for evidence-based behavioural interventions and targeted communication campaigns. It delivers a proof of concept for scalable, audience-specific behaviour change approaches that can be refined, implemented, and evaluated in future research.

Data from multibeam echosounder surveys taken as part of the Ningaloo Outlook project were classified into various seafloor cover types according to their hardness, rugosity and depth. The classifications were validated with towed video ground truth where it was available. This dataset describes two AOIs which are explicitly part of the Ningaloo Outlook Deep Reefs project. Substratum classifications were applied using multibeam backscatter angular response curves along with rugosity as input to a maximum likelihood classifier. See original metadata record(s) and associated attached documents for accuracy estimates, alternate classification techniques, and additional surveyed areas. https://doi.org/10.25919/kssa-5b46 https://doi.org/10.25919/kttc-x397 https://doi.org/10.25919/8m65-7k26

Aquatic flora surveys were conducted in the Leschenault Estuary in April 2009. This data is part of the 2013 report "Synthesis of seagrass mapping studies" conducted by the Water Science Branch of the Department of Water. Surveys were initially conducted by the WA Department of Water together with Geoscience Australia. The objective of these surveys was to collect baseline data on seagrass composition and distribution in key estuaries of southern and south-western WA. This data was acquired by the ACEAS Seagrass Group as part of the 2013 Australia-wide risk assessment of Seagrass. Surveys were conducted again 2015-2023 (February 2015, February and March 2016, February 2017, February and March 2018, February 2019, February and March 2020, February 2021, February and March 2022, and February and March 2023) by the Department of Water and Environmental Regulation as "Leschenault Estuary Seagrass Survey". The datasets making up the 2009 Leschenault Estuary seagrass survey data are: WA_Leschenault_SAV_sites - point dataset of species presence/absence and survey methodology at each site. WA_Leschenault_SAV_polygons - polygon dataset showing interpolated percentage cover in polygons derived from site points. This record provides access to the initial WA DoW surveys. See associated DWER records in Data WA catalogue for access to newer surveys at this site.

This record provides an overview of the NESP Marine and Coastal Hub project "Improving knowledge transfer to support Australian Marine Park decision making and management effectiveness evaluation". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia’s network of Commonwealth Marine Parks plays a central role in conserving marine biodiversity, supporting sustainable use, and protecting cultural and recreational values. With over 60 parks spanning diverse habitats - from shallow coastal areas to deep offshore canyons - effective and adaptive management depends on access to reliable, fit-for-purpose data and data products that reflect the condition of park values and the pressures acting upon them. This project improved the capacity to assess the effectiveness of Australian Marine Park (AMP) management by identifying and evaluating priority data and data products required for characterising marine systems and management effectiveness. It worked closely with Parks Australia to assess the availability, quality, and delivery mechanisms of existing datasets, and determined whether these were operationally viable, maintainable over time, and aligned with FAIR data principles. Technical assessments considered consistency of formats, use of standardised vocabularies, as well as machine-readability and the use of national standards for data and collection methodologies. Using available data, knowledge, and existing data infrastructure, the project developed methods for estimating the condition of AMP values (excluding cultural values) and for assessing management effectiveness. Recommendations were provided to improve the discoverability, accessibility, and usability of priority data products through national platforms. Outcomes of the project include a clearer understanding of existing data gaps and a practical foundation for improving future AMP assessments. Parks Australia was equipped with a structured assessment of current data suitability and availability, a demonstration of condition estimation methods, and strategic recommendations to enhance data delivery and alignment with park management cycles. This work directly contributes to the Marine and Coastal Hub’s Protected Place Management Initiative and supports national efforts to build integrated data systems for marine estate monitoring and reporting.

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Assessing changes in black rockcod abundance and size". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The Black Rockcod (Epinephelus daemelii) is a large, reef-dwelling species that can live for more than 60 years. In Australia it occurs along the coast of New South Wales, including at Lord Howe Island. Black Rockcod populations have been significantly reduced here due to overfishing, accidental hooking, and loss or degradation of estuarine and intertidal nursery habitats. As a result, the species is listed as Vulnerable under Commonwealth and NSW legislation. Despite having been protected from fishing in NSW since 1983, Black Rockcod are still taken illegally, or caught incidentally and released, which can lead to mortality post-release from embolism. Long-term population monitoring is a high priority identified by the species’ recovery plan and the NSW Fisheries Scientific Committee. In 2010, a broadscale baseline survey (81 sites) was undertaken in northern NSW and Lord Howe Island, followed by smaller surveys every four to five years. This project repeated the initial 81 baseline site surveys to assess if protection measures, such as marine protected area sanctuary zones, are assisting in recovery of black rockcod. This contributed to a 13-year time series (2010 – 2023) that was used to examine distribution and population structure of rockcod to assess if recovery actions being implemented are effective. Outputs • underwater visual census (UVC) data for black rock cod [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub project "Mapping critical Australian sea lion habitat to assess ecological value and risks to population recovery". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australian sea lion populations have declined by more than 60% over the past four decades. Abundance and trends vary markedly across the species range, suggesting that localised risk profiles from threats - such as bycatch, marine pollution, and habitat degradation - vary at small spatial scales. Fine scale variation in habitat use is thought to underpin these differences, yet knowledge about Australian sea lion's dependency on key habitats and their vulnerability to human impacts is limited. This project deployed compact animal-borne cameras with GPS and motion sensors on eight adult female sea lions at two key colonies: Seal Bay (Southern Kangaroo Island Marine Park) and Olive Island (Western Eyre Marine Park). The devices recorded nearly 80 hours of footage over 560 km of seabed, identifying six distinct benthic habitat types, including previously unmapped rocky reefs and kelp forests. The footage was used to develop fine-scale habitat maps using machine learning models, providing a valuable baseline for assessing ecological value, foraging intensity, and the effectiveness of protected areas. This innovative approach complements traditional seafloor mapping and offers a scalable, cost-effective method for locating and monitoring critical habitats for endangered marine species. The results directly inform recovery planning, fisheries management, marine park design, and the identification of Biologically Important Areas. Ongoing camera deployments at Seal Bay and new sites along the western Eyre Peninsula will improve understanding of sea lion colony-specific behaviours and contribute to long-term monitoring of habitat change, diet, and emerging threats. Outputs • Tracking data from sea lion-deployed tags: location, depth, time, temperature, light, acceleration [dataset] • Timestamped video footage from sea lion-deployed cameras [dataset] • Final project report [written]
