Abstract To address the increasing need for volunteers in countries experiencing conflict and natural disasters, this study examined young adults’ willingness to volunteer abroad in a “higher risk” country. Young Australian adults ( N = 163) completed an online survey of Prototype Willingness Model constructs, risk perceptions, and trust in the organization. Attitude, subjective norm (approval from others), perceived similarity to a typical volunteer, risk susceptibility, risk severity, and trust in the charitable organization significantly predicted volunteer willingness, with trust in the organization influencing a number of the antecedents to volunteer willingness. Risk susceptibility had an unexpected positive relationship with volunteer willingness, highlighting the importance of acceptance of associated risks for openness to volunteering in higher risk settings. This study contributes to our understanding of volunteering abroad in higher risk countries, informing efforts to increase the prevalence of international volunteering, essential to address the imbalance of resources globally.
