INTRODUCTION: Exposure to natural hazards such as fire, drought, floods, and earthquakes can have negative impacts on physical and mental health and wellbeing. The social and structural factors contributing to individual and community vulnerability also influence responses to disaster and the resulting consequences on health and wellbeing. Experiencing disasters like bushfires amplifies the impacts of inequality, magnifying existing disparities and contributing to additional psychological burdens of grief, trauma and adaptive challenge. There is a need to understand how vulnerability can influence responses to disaster, and to identify factors that develop and foster resilience in the context of increasing disasters and vulnerability. MATERIALS AND METHODS: This protocol will describe the methodology of two scoping reviews: the first will describe the mental health outcomes of vulnerable populations after droughts and bushfires; the second will identify and describe strategies that promote community resilience in vulnerable populations in the context of a disaster. A thorough search will be conducted in relevant databases. Studies will be limited to English language. The reviews will be reported using the 22-item checklist for the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Methodological quality of the included papers will be assessed using the Joanna Briggs Institute's critical appraisal tools. RESULTS & CONCLUSIONS: The two scoping reviews described in this protocol will have broad relevance in the context of increasing and intensifying disasters, and will especially consider the compounded impact of disaster on vulnerable communities. Findings will contribute directly to the design and implementation of solutions to improve post-disaster health and wellbeing and community resilience.
