This article compares evidence given to the 1970s Commonwealth Commission of Enquiry into Poverty by a social worker from Armidale with that of a group of foster carers in Adelaide. It does so to illuminate the power struggle underway between volunteers, professionals and experts at a key moment in Australia’s social welfare history. The testimonies provide two very different perspectives on the challenges of social welfare professionalisation. Analysing them allows a deeper exploration of those challenges, which, to date, have been under-explored, while bringing a greater understanding of the factors that shaped the creation of enquiry submissions.
