Young people transitioning from out-of-home care (generally called care leavers) are recognised globally as a vulnerable group. In the last eighteen months, four Australian jurisdictions have extended state care till twenty-one years in an attempt to advance the life opportunities of this cohort. These initiatives are strongly influenced by extended care programmes in the USA and England, which have reported improved outcomes for care leavers. This article interrogates formal public evaluations of these extended care programmes with a particular focus on their eligibility criteria that have determined which groups of care leavers are included or alternatively excluded and the identified strengths and limitations of the programmes. Additionally, we consider cross-cultural differences in leaving care populations and variations within the broader social policy context of these jurisdictions, which may also impact on the effectiveness of policy transfer. Some conclusions are drawn about key factors that may enhance the success of extended care programmes.
