Introduction
Independent data validation in commercial fishing is becoming more commonplace in Australia. Fisheries in Australia provide a significant income to the country, and play an integral role in our food security, livelihoods, and social lives. Challenges such as overfishing, illegal and unreported fishing, bycatch and interactions with threatened, endangered, or protected species, provide hinderances to fully sustainable fishing. The increasing demands on the marine environment for energy production, marine protected areas, and recreational use are leading management of fisheries in Australia to be spatially based. Currently, some jurisdictions in Australia (e.g. Queensland, Tasmania, Australian Fisheries Management Authority), have already introduced independent data validation programs. The aim of these programs is, on the surface, to improve the quality, reliability, and transparency of fisheries data in Australia. However, there is considerable distrust from commercial fishers regarding a) data collection methods; b) the use of collected data; c) the legality of both collecting, and storing data; d) the cost of installing and running the systems – both financial and physical; e) ongoing maintenance of systems; f) the reliability of data from the systems, and g) whether the data are actually going to be used for their intended purpose.
Recognising the need for greater transparency in fisheries data, and the general distrust of these systems, this project aims to provide an external review of data validation options, uses, and opportunities within Australia.
Objective
The primary objective of this project is to address industry stakeholders’ concerns regarding the reliability and transparency around the collection, use, and storage of independent fisheries data validation methods. This will be achieved by conducting a comprehensive, and systematic review of independent data validation (IDV) processes both within Australia, and globally. The review will then allow us to evaluate IDV mechanisms, legal implications around IDV, and economic considerations of various IDV methods, including whether any value-add opportunities exist. The project will provide outputs that will allow for efficient choice of relevant data validation options for particular fisheries in Australia, while outlining the pros and cons for relevant methods. The results will enhance confidence for commercial fishers, and fishery managers around choosing the best data validation options for their fishery.

Methods
1) Systematic literature review to determine available independent data validation methods
We will research and compile a comprehensive list of independent data validation methods (IDV) that are available currently, and in the future through a systematic literature review. The systematic literature review will cover peer-reviewed literature and relevant reports published globally in the last 10 years. The review will examine existing technologies, methodologies, and best practices in IDV used in relevant industries (not just limited to fisheries), and present a summary of current best practice, and likely additions in the future to IDV. The review will include information on the potential add-on possibilities associated with IDV methods – which will be expanded upon in (4). The review will equip industry stakeholders with the knowledge to fully understand the range of options in IDV, and those most suitable for their fishery.
2) Stakeholder consultation – strengths, weaknesses, opportunities, and threats (SWOT)
Within the project we will conduct an extensive survey across a diversity of fishers across Australia (including those that have already implemented IDV, and those that have not), to gather insight into the perceptions of independent data validation (IDV). Through this SWOT analysis, we will identify the strengths, weaknesses, opportunities, and threats associated with current IDV mechanisms from the perception of industry, and map this to the published literature in point (1). This will allow us to address concerns from industry and identify those concerns that are representative of IDV globally. This analysis will serve as a foundational understanding of the industry's readiness and receptiveness towards adopting IDV and provide industry with independent information relating to their concerns.
3) Review of legal implications for IDV implementation, including case studies
Alongside the systematic literature review in (1), we will conduct a thorough review of Australian legislation relating to IDV. This will include both publicly available legal documents, and information regarding internal policy documents from governmental departments. The review will include fisheries legislation and policy, data ownership, data licencing, data storing, and Freedom of Information requests that have occurred within the context of fisheries data relating to IDV. Some of industry’s concerns regarding IDV relate to how the data will be used outside of a fisheries context, and we will ensure that our legislative review includes advice regarding data use. The review will provide information on Australian legislation relating to IDV, and data collection, storage and sharing.
4) Assessment of value-add opportunities
Building upon the findings from (1-3), we will assess the value-add opportunities presented by adopting IDV. This assessment will include a financial model similar to the one in the report “Challenges, Opportunities, and Costs of Electronic Monitoring” that was published by The Environmental Defence Fund in 2016 [REF] that will provide industry with a tool to investigate the costs and benefits of adopting various IDV methods. Additionally, we will explore how IDV can contribute to improved market access, stakeholder relationships, and sustainability credentials for fisheries businesses, alongside the potential of improved data quality from fisheries. Our work will build on our planned literature and legal review of independent data validation (IDV) and provide potential ‘value-add’ opportunities for commercial fishers, based on the information in the review. Some potential benefits may include:
• Increased or improved market access (where IDV can demonstrate aspects of sustainable fishing practices required by, for example, sustainability labels such as the Marine Stewardship Council Certification).
• Potential for selling or distribution of data to researchers / third parties (depending on data owners.

We will include updated outcomes and outputs from the project as detailed below, and will look to refine these with the Professional Fishers Association of New South Wales, commercial fishers, and the Steering Committee.

5) Best Practice Guidelines
We will provide industry and fisheries resource managers with a Best Practice Guideline relating to IDV as a formal result from the steps (1-4) above.
6) Engagement with Industry Stakeholders
Throughout the project, we will actively engage with industry stakeholders through workshops, focus groups, and one-on-one consultations to discuss project findings. This engagement will provide a platform for dialogue, collaboration, and knowledge sharing, fostering a sense of ownership and commitment among stakeholders towards implementing IDV practices. We will facilitate target outreach efforts engaging with industry associations, peak bodies, government agencies, and non-governmental organizations (NGOs), and other interested parties on the project progress.

The marine waters of Southeast (SE) Australia are one of a series of global ocean-warming hotspots. In this region, the East Australian Current is extending pole-wards, resulting in warming of ocean surface at a rate four times the global average. Many species have extended their distributions southward, with potential changes in local abundance. In addition, climatic extreme events, such as marine heatwaves, are leading to additional impacts in the region. Projections show that these changes, and the associated biological responses, are expected to continue in the next century.

In this hotspot lie important fisheries, providing the bulk of fresh fish to Melbourne and Sydney markets. The Southern and Eastern Scalefish and Shark Fishery (SESSF) has a total catch of about 20,000t and a value above $80 million. Concerns about the ecological, economic and social sustainability of this fishery raised in the public, and by scientists, over the years, have prompted a series of management responses, initiatives and regulations. In the hotspot also lies an Australian Marine Reserve network established to protect and maintain marine biodiversity and ensure the long-term ecological viability of Australia's marine ecosystems.

Observations from the Australian commercial fisheries regulator, the Australian Fisheries Management Authority (AFMA) suggests that the abundance of some species have declined, while others have increased. Additionally, some species that have been historically over-fished do not seem to be recovering despite reduced fishing pressure. The South East Australian Marine Ecosystem Survey will seek to answer the questions:

1. Despite reduced fishing pressure, have fish abundances in the SESSF really declined in 25 years? And if so, why?

2. Are species shifting their ranges to places outside of where they have been historically found, including to the continental slope?

3. What are the prospects for the future?

Comprehensive bio-physical and ecosystem assessments of the shelf were last conducted 25 years ago. This project will repeat the surveys to document changes, and will establish a new baseline for the continental slope. Specifically, it will help answer the broad questions:

1. How and why have fish assemblages and species abundances changed in the southeast ecosystem, and can the causes be mitigated?

2. How does this affect the multiple-use management of the region for fisheries, conservation and biodiversity and the hive of activity from oil & gas, and renewable energy sectors?
