Paternal imprisonment creates a significant risk for the intergenerational transmission of offending. However, there is little research on the mechanisms underpinning this risk, including how paternal imprisonment interrupts parenting and father–child relationships. Culturally relevant research is also essential in the context of high imprisonment rates of Indigenous Australian men. We conducted interviews with 41 Indigenous Australian fathers from two prisons in North Queensland to examine their identities as fathers in prison and the barriers associated with maintaining relationships with their children. Findings are discussed in relation to contact and distance; intergenerational absence of fathers; paternal involvement through play, care and culture; and diminished opportunities for men’s parental and cultural generativity. We consider the implications of the findings for children’s well-being.
