The Australian Child Support Scheme impacts on the lives of many Australian families. Yet the Australian evidence base informing child support policy development is relatively sparse and lacks coherence. In this article, we employ an equity framework to consolidate the published Australian empirical child support research in order to identify gaps in current knowledge and assess the various layers of competing interest inherent therein. While researchers have begun to examine the financial outcomes of the new Australian Child Support Scheme, work is urgently needed to understand the effects that the new scheme has on children, payees and payers, and how these effects operate. We conclude by proposing an agenda for future Australian child support research that focuses on the aims of the scheme and the four equity principles we employ, namely, horizontal, vertical, gender, and intergenerational equity.
