Despite growing investment in mangrove restoration across the Great Barrier Reef (GBR) catchment, stakeholder support remains a critical barrier. While ecosystem services (ES) such as coastal protection and biodiversity are often highlighted in environmental management strategies, negative perceptions of nature (i.e. ecosystem disservices -EDS) are rarely addressed, despite their influence on public support. This study surveyed 869 residents across 27 Local Government Areas in the GBR to explore how perceptions of both ES and EDS, as well as sociodemographic factors, influence support for mangrove restoration. Using binomial regression models and sociodemographic data, we found that mangroves are generally viewed positively and that these perceptions were predictors of support. Overall, 87.6% of respondents expressed support for restoration. Positive perceptions, such as viewing mangroves as biodiversity habitat and a legacy for future generations, increased support. However, negative views—especially concerns about land productivity loss—reduced support by up to 69%. Sociodemographic trends revealed that younger people, males, or residents in high-density areas, such as cities, showed greater support, while participants in less densely populated areas emphasised cultural services but also risk-related disservices (e.g., crocodiles). These findings highlight the need for tailored communication strategies that both amplify positive narratives and acknowledge public concern. This presentation provides insights for restoration planners, communicators, and community organisations to better align restoration efforts with public values in the region.
