This report presents the main results of the 2022 survey aimed to provide an understanding of
Australian attitudes toward the development and deployment of novel restoration and
adaptation options in the Great Barrier Reef (GBR).

Findings of a representative survey of Australians, industry and stakeholder interviews and scoping the issues and needs of Traditional Owners.

The complexity and gaps to be addressed in the regulatory environment for restoration and adaptation R&D and activities in the Great Barrier Reef.

The potential interventions investigated by the Reef Restoration and Adaptation Program; knowledge gaps in understanding benefits, risks and feasibility.

Summary of the current global knowledge of coral restoration methods and practises, highlighting the common issues encountered as the field has evolved.

Possible delivery methods for the proposed Reef interventions, analysing cost and scale implications for each, and identifying potential synergies and efficiencies.

Preliminary results of ecological modelling and analyses of the likely trajectories of coral condition over time under climate change, with and without intervention.

Discussions on how the broader decision-support system needs will be met were continuing at the time of the release of the RRAP reports and involve multiple stakeholders and research providers. Given this, the recommendations in this report are now obsolete.

Cost-benefit analysis of proposed Reef interventions, in different climate scenarios, in different combinations, to understand trade-offs and optimise decisions.

Combining economic data with forecast coral condition to estimate current and future benefits of proposed interventions, under different climate change scenarios.

Engineering concepts for systems to grow and deploy new corals on the Reef, at scale, as researched and developed by the Reef Restoration and Adaptation Program.

Modelling to investigate cold-water injection as a potential intervention, to cool reef waters and help prevent thermal stress, which can lead to coral bleaching.
