The increasing frequency of natural disasters, such as bushfires, pose significant challenges for countries like Australia. This research investigates the changes in social connectedness following a bushfire disaster in 2019 in the rural community of Cudlee Creek, South Australia, Australia. Research has repeatedly highlighted the importance of social connectedness, social capital and secure attachment relationships in mitigating post-disaster mental health concerns. This study utilised semi-structured interviews with eight parent–child dyads twenty months post-disaster to understand changes in parent–child relationships, the quality of extended family ties and the role of the broader community in recovery and coping. Reflexive thematic analysis revealed three themes: (i) differences in children and parents in preferred forms of social support; (ii) a thinning of previously available support and (iii) altered patterns of communication in the parent–child relationships. The findings highlight the complex interactions of multi-systemic and intersectional disadvantages on social isolation and loss of social capital following disasters. The results also highlight the influence of stoic beliefs on patterns of miscommunication in parent–child dyads in rural contexts. Implications for the implementation of community-wide post-disaster supports, sociometric approaches to mental health screening and assessment, and targeted interventions for rural families.
