Approximately 3600 Korean children have been adopted to Australia, as of 2023. Existing studies have tended to approach transnational or intercountry adoption from child development, social welfare, or identity perspectives. Research on Korean adoption to Australia is relatively scarce. The current article approaches the population from a migration perspective, building on Richard Weil’s conceptualization of transnational adoption as “quiet migration.” Drawing on both Korean-language data from South Korean governments and Australian data, the authors analyse Korean adoption to Australia as a state-sanctioned transnational migratory mechanism that facilitated the orderly movement of children from so-called “deficient” families of predominantly single mothers in South Korea to adoptive families in Australia. Situating adoption practices within the socio-political contexts and larger migration trends of both countries, the authors identify multiple enabling factors for channelling the ‘quiet’ flow of Korean children for adoption and argue the very ‘quietness’ of the adoption system is a source of concern despite Australia’s relatively stringent regulations. A migration perspective and analysis of these enabling factors contributes to the conceptualization of adoption as a socio-political state-sanctioned phenomenon, rather than a solely private family affair.
