High Seas Biodiversity Bill 2026

High-Level Summary
The High Seas Biodiversity Bill 2026 aims to implement Australia's international obligations under the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement). This legislation establishes a regulatory framework for marine genetic resources, area-based management tools (including marine protected areas), and environmental impact assessments in areas beyond national jurisdiction, ensuring Australia's commitment to global ocean health.

Summary
The High Seas Biodiversity Bill 2026 (the Bill) is designed to implement Australia’s international obligations under the Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement) [Explanatory Memorandum page 2]. This BBNJ Agreement is an implementing agreement under the 1982 United Nations Convention on the Law of the Sea (UNCLOS), which serves as the comprehensive legal framework for all ocean activities and includes a general obligation to protect and preserve the marine environment (Article 192) [Explanatory Memorandum page 2]. The core purpose of the BBNJ Agreement, and consequently the Bill, is to ensure the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction. These areas encompass the water and seabed beyond the limits of national jurisdiction, extending beyond 200 nautical miles from States’ baselines [Explanatory Memorandum page 2]. The BBNJ Agreement addresses four main topics:
  1. Marine genetic resources, including benefit sharing.
  2. Area-based management tools, such as marine protected areas.
  3. Environmental impact assessments.
  4. Capacity building and the transfer of marine technology.
In addition, the Agreement enhances coordination and cooperation across existing sectoral and regional regimes [Explanatory Memorandum page 2]. The Bill translates these international obligations into Australian law by creating a new regulatory regime covering:
  • Part II (Marine Genetic Resources and Digital Sequence Information): This part regulates activities related to marine genetic resources and digital sequence information (DSI) from areas beyond national jurisdiction. It imposes international obligations for benefit sharing, capacity development, research and innovation, and the development and transfer of marine technology [Explanatory Memorandum page 2, 10]. Key mechanisms include a notification-based regime for collecting and utilising these resources, requirements to deposit them in regulated databases or repositories, and associated reporting and record-keeping duties [Explanatory Memorandum page 13].
  • Part III (Area-Based Management Tools): This section establishes a framework for area-based management tools, including marine protected areas, to protect, preserve, restore, and maintain biological diversity and ecosystems in areas beyond national jurisdiction [Explanatory Memorandum page 3, 58]. Parties can propose these tools for decision by the Conference of the Parties (COP) [Explanatory Memorandum page 3, 58]. If Australia objects to an established tool, it is still required to adopt equivalent alternative measures to the extent practicable [Explanatory Memorandum page 58].
  • Part IV (Environmental Impact Assessments): This part mandates an environmental impact assessment (EIA) process for planned activities under Australia's jurisdiction or control that pose a risk of harm to the marine environment in areas beyond national jurisdiction [Explanatory Memorandum page 3, 70]. States are responsible for screening and assessing these activities, only authorizing them once appropriate measures are in place to prevent significant adverse impacts, and ensuring ongoing compliance with Part IV requirements [Explanatory Memorandum page 3, 70].
Beyond these specific implementations, the Bill also introduces a modern compliance and enforcement framework, outlining Commonwealth regulatory powers, offence and civil penalty provisions, and audit and information gathering capabilities to ensure adherence to the Bill [Explanatory Memorandum page 3, 154]. The Explanatory Memorandum states that the Bill is expected to have no financial impact on the Australian Government Budget [Explanatory Memorandum page 4].

Argument For
Normative Bases
  1. Environmentalism
  2. Legal Principle
  3. National Prestige / Patriotism

The High Seas Biodiversity Bill 2026 is a crucial legislative step towards safeguarding global marine biodiversity in areas beyond national jurisdiction. It directly supports the conservation and sustainable use of marine biological diversity, which is fundamental for a healthy and resilient ocean. A healthy ocean provides invaluable ecosystem services, such as oxygen production and carbon dioxide absorption, and underpins Australia's vital marine industries like tourism, fishing, and aquaculture. The establishment of marine protected areas and other area-based management tools, facilitated by this Bill, will enhance the long-term viability of fish stocks and offer improved protection for migratory megafauna [Explanatory Memorandum page 2, 4]. This demonstrates a proactive commitment to protecting our shared planetary environment [Judgment].

Furthermore, this Bill ensures Australia's adherence to its international legal obligations. By implementing the BBNJ Agreement, an essential implementing agreement under the UNCLOS, Australia upholds its responsibilities under international law to protect and preserve the marine environment (Article 192). The Bill provides the necessary domestic legal framework for Australia to meet its commitments regarding marine genetic resources, area-based management tools, and environmental impact assessments, thus reinforcing the global legal framework for ocean governance [Explanatory Memorandum page 2]. This is vital for maintaining a rules-based international order in environmental matters [Judgment].

As a major coastal state with extensive maritime jurisdiction, ratifying and implementing the BBNJ Agreement enables Australia to assume a leading and active role in global ocean conservation and sustainable use. This strengthens Australia's international environmental leadership and allows it to significantly contribute to shaping global rules for managing the high seas in alignment with national interests. Moreover, the Bill fosters collaboration with other States in the region to establish and manage marine protected areas, which in turn bolsters bilateral relations and facilitates the exchange of critical expertise [Explanatory Memorandum page 2, 4]. Such leadership enhances Australia's standing and influence on the international stage.


Argument Against
Normative Bases
  1. Value-Neutral / Epistemic Objection

While the stated objective of protecting high seas biodiversity is laudable, the High Seas Biodiversity Bill 2026 introduces a complex and potentially onerous regulatory framework that may inadvertently hinder scientific research and innovation, particularly concerning marine genetic resources and digital sequence information. The Bill imposes extensive requirements for pre- and post-collection notices, mandates the deposition of materials in regulated databases, and necessitates detailed reporting and record-keeping for Australian entities operating in areas beyond national jurisdiction [Explanatory Memorandum page 13, 20-47]. These comprehensive compliance obligations, combined with strict liability offences and substantial civil penalties (e.g., up to 1,000 penalty units for certain environmental impacts) for non-compliance, could create significant administrative and financial burdens for Australian researchers and industries [Explanatory Memorandum page 98, 155]. This heightened regulatory load may discourage engagement in crucial high seas research and development, potentially stifling the very scientific progress and capacity building the BBNJ Agreement aims to promote [Judgment].

Moreover, certain provisions within the Bill raise concerns regarding privacy and the free flow of information, which could have unintended negative consequences. For instance, Clause 121 abrogates the common law privilege against self-incrimination, compelling individuals to provide information even if it could be self-incriminating (albeit with use immunity in criminal proceedings) [Explanatory Memorandum page 133, 159]. Additionally, Clause 109 requires the publication of the names of individuals who hold relevant certificates or authorisations on the High Seas Biodiversity Register [Explanatory Memorandum page 117, 162]. Although these measures are justified by the Bill for transparency and enforcement, they could create a chilling effect. Researchers and commercial entities might become reluctant to engage in activities or share valuable scientific data due to concerns about personal data privacy, public scrutiny, or the risk of incurring severe penalties for what might be minor administrative oversights. This could ultimately undermine the broader objectives of open access and equitable benefit-sharing under the BBNJ Agreement [Explanatory Memorandum page 12, 13, 162].
