Research from the Australian National University linking poker machine density to family and domestic violence rates in New South Wales (NSW) has become a recurring reference point for advocacy groups pushing for tougher gambling reform, as separate federal and state-level regulatory processes move forward in parallel.
The ANU study, commissioned by the NSW Responsible Gambling Fund and published in March 2026, analyzed longitudinal data from 2017 to 2023 across NSW local government areas, tracking changes in gaming machine numbers against police-recorded domestic violence rates over time rather than comparing different areas at a single point.
The researchers found a statistically significant, though small, association between rising machine numbers and rising family and domestic violence incidents, with the effect strongest in metropolitan Sydney and the state’s north and north-west. A second stage of the research involved interviews with 33 service providers across gambling support, domestic violence, mental health and child and family services. The report’s authors noted limitations, including that police-reported data likely understates true incident rates and that the analysis did not control for some relevant variables, such as proximity to alcohol outlets.
The findings have been cited repeatedly by Australian harm-reduction advocates over the following months. Wesley Mission used the study to call for a mandatory overnight shutdown of poker machines in NSW between midnight and 10am. The same research underpinned a private member’s bill introduced by independent MP Dr Monique Ryan in March, with crossbench support including Senator David Pocock, seeking to formally classify gambling harm as a public health issue under the Australian Centre for Disease Control. St Vincent de Paul Society has also referenced the study in recent commentary linking gambling losses to homelessness presentations.
The advocacy push runs alongside, but separately from, the federal government’s online gambling advertising reforms. The Commonwealth’s reform package stems from a 2023 parliamentary inquiry led by the late Peta Murphy, which made 31 recommendations including a full phased ban on gambling advertising. The government’s formal response, released on 12 May 2026, adopted a more limited package — restrictions on wagering ads during live sport and on broadcast radio during school pick-up hours, a cap on television ad frequency, and an opt-out model for online platforms — while referring several of the Murphy Review’s recommendations to state and territory governments. Exposure draft legislation is currently in a targeted consultation process with broadcasters, sports codes and harm-reduction groups, ahead of an intended 1 January 2027 commencement. St Vincent de Paul’s national president described the package as a partial regime that leaves children exposed to continued advertising.
The distinction between the two tracks is relevant to how the research has been used in public commentary. The federal package addresses online wagering advertising under the Interactive Gambling Act, a Commonwealth responsibility. Poker machines remain a state regulatory matter, and the ANU research speaks specifically to gaming machine density rather than online wagering. Advocacy commentary in the Australian press has at times blended the two issues into a single gambling harm narrative, using the NSW findings to argue both that the federal advertising reforms do not go far enough and that NSW should introduce machine-specific restrictions the federal package does not contemplate.
