Abstract: An exceptionally large coral Porites sp. has been identified and measured at Goolboodi (Orpheus Island), Great Barrier Reef (GBR). This coral was measured in March 2021 during citizen science research of coral reefs in the Palm Islands group. We conducted a literature review and consulted scientists to compare the size, age and health of the Porites with others in the GBR and internationally. This is the largest diameter Porites coral measured by scientists and the sixth highest coral measured in the GBR. The health of the Porites was assessed as very good with over 70% live coral cover and minor percentages of sponge, live coral rock and macroalgae. An estimated age of 421–438 years was calculated based on linear growth models. Manbarra Traditional Owners were consulted and suggested that the Porites be named Muga dhambi (big coral) to communicate traditional knowledge, language and culture to indigenous, tourists, scientists and students.

Abstract: While coral reefs in Australia have historically been a showcase of conventional management informed by research, recent declines in coral cover have triggered efforts to innovate and integrate intervention and restoration actions into management frameworks. Here we outline the multi-faceted intervention approaches that have developed in Australia since 2017, from newly implemented in-water programs, research to enhance coral resilience and investigations into socio-economic perspectives on restoration goals. We describe in-water projects using coral gardening, substrate stabilisation, coral repositioning, macro-algae removal, and larval-based restoration techniques. Three areas of research focus are also presented to illustrate the breadth of Australian research on coral restoration, (1) the transdisciplinary Reef Restoration and Adaptation Program (RRAP), one of the world’s largest research and development programs focused on coral reefs, (2) interventions to enhance coral performance under climate change, and (3) research into socio-cultural perspectives. Together, these projects and the recent research focus reflect an increasing urgency for action to confront the coral reef crisis, develop new and additional tools to manage coral reefs, and the consequent increase in funding opportunities and management appetite for implementation. The rapid progress in trialling and deploying coral restoration in Australia builds on decades of overseas experience, and advances in research and development are showing positive signs that coral restoration can be a valuable tool to improve resilience at local scales (i.e., high early survival rates across a variety of methods and coral species, strong community engagement with local stakeholders). RRAP is focused on creating interventions to help coral reefs at multiple scales, from micro scales (i.e., interventions targeting small areas within a specific reef site) to large scales (i.e., interventions targeting core ecosystem function and social-economic values at multiple select sites across the Great Barrier Reef) to resist, adapt to and recover from the impacts of climate change. None of these interventions aim to single-handedly restore the entirety of the Great Barrier Reef, nor do they negate the importance of urgent climate change mitigation action.

Abstract: Scientific, tourism and non‐government organisations collaborated to design and undertake a small‐scale coral outplanting intervention at Fitzroy Island, the Great Barrier Reef (GBR), Cairns, Australia. Activities were implemented to assist recovery of a reef showing signs of reduced coral cover after recent coral bleaching and to trial potential for implementation of work of this kind by community members. In December 2017, 240 coral fragments were collected and deployed on mid‐water coral nursery infrastructure. Ten months later, 96 corals (˜15 cm) were outplanted onto bare sections of the surrounding reef rock at depths of 2–8 m. Monitoring was undertaken to measure changes in coral cover at treatment and control locations to determine the potential of using coral outplanting intervention to assist the recovery of degraded reefs. We found no significant difference in live coral cover between controls and treatment over a 12‐month period. Although statistically insignificant, we observed an increase in live coral cover in treatment plots (9.8%) and control plots (2.2%), indicating natural recovery processes occurring across the reef. Total number of fish species and abundance increased significantly over time. Although the outplanting may not have been needed in this case, as a pilot project and the first coral nursery and active reef restoration project in the GBR Marine Park, the research provided valuable lessons associated with project collaboration and planning, site selection, monitoring and natural recovery vs restoration.

Abstract: Coral reef restoration is a rapidly growing movement galvanized by the accelerating degradation of the world's tropical coral reefs. The need for concerted and collaborative action focused on the recovery of coral reef ecosystems coalesced in the creation of the Coral Restoration Consortium (CRC) in 2017. In March 2020, the CRC leadership team met for a biennial review of international coral reef restoration efforts and a discussion of perceived knowledge and implementation bottlenecks that may impair scalability and efficacy. Herein we present six priorities wherein the CRC will foster scientific advancement and collaboration to: (1) increase restoration efficiency, focusing on scale and cost‐effectiveness of deployment (2) scale up larval‐based coral restoration efforts, emphasizing recruit health, growth, and survival (3) ensure restoration of threatened coral species proceeds within a population‐genetics management context (4) support a holistic approach to coral reef ecosystem restoration (5) develop and promote the use of standardized terms and metrics for coral reef restoration and (6) support coral reef restoration practitioners working in erse geographic locations. These priorities are not exhaustive nor do we imply that accomplishing these tasks alone will be sufficient to restore coral reefs globally rather these are topics where we feel the CRC community of practice can make timely and significant contributions to facilitate the growth of coral reef restoration as a practical conservation strategy. The goal for these collective actions is to provide tangible, local‐scale advancements in reef condition that offset declines resulting from local and global stressors including climate change.
