La Trobe University’s Centre for Alcohol Police Research has released a report, which found a 40 percent increase in domestic violence on State of Origin Wednesday matches in New South Wales, as compared to regular Wednesday nights.

The Foundation for Alcohol Research and Education research manager, Dr Melanie Pescud said that the NRL has a responsibility to acknowledge the research and create a plan to solve the problem, such as lowering the game’s extensive sponsorships and advertising of alcohol.

The report comes before the second Origin match at Sydney’s Olympic Park, which is on Sunday.
