This study addresses a gap in understanding the relationship between eco-emotions, mental health and pro-climate actions among adolescents living in rural Australia. A mixed methods approach was used to triangulate survey data (N = 145, mean age = 13.09 years, SD = 0.73) and photo-elicitation focus groups (n = 21, mean age = 12.95 years, SD = 0.58). Bivariate and moderation analyses of the survey revealed that a stronger connection to nature moderated the relationship between eco-anger and mental ill-health symptoms and pro-climate actions, respectively. Thematic analysis of the focus group data provided deeper insights, showing that participants with a connection to nature felt a sense of responsibility and willingness to engage in pro-climate actions. Triangulation of the data revealed a gap between awareness and action. While survey data indicated low levels of individual and collective action, qualitative findings provided an explanation that although many participants expressed a desire to be involved in climate action, they identified a need for more practical support and guidance from adults. The study provides insights into the need for practical, targeted interventions that support mental health and encourage constructive climate-related behaviours, particularly by leveraging the protective role of connectedness to nature.
