Conducted by the Australian Environment and Communications Reference Committee (ECRC), the survey of over 7,000 gamers comes to the conclusion that loot boxes are "psychologically akin to gambling". Adding that the results suggest a link between loot boxes and gambling-related harm.
The results were made public via a hearing, which you can read the transcript of here
, which was chaired by Senator Steele-John of the Greens.
The hearing begins with the confirmation that "not all loot box mechanics are homogenous, not all loot box systems are the same", before going on to cite that 45% of all games with loot box mechanics met all five psychological criteria for gambling. When it came to links between loot box items and real-world currency the first game mentioned was Counter-Strike: Global Offensive followed by PlayerUnknown's Battlegrounds.
Star Wars Battlefront II also made an appearance, specifically in reference to its pay-to-win mechanics. The in-depth analysis is quick to note the differences between pay-to-win and the cosmetic-only approaches of games like Overwatch, with the overall conclusion being that loot boxes exploit gambling disorders.
A recommendation of a parental warning label saying something like this game features "in-game gambling content" was proposed. In addition to the idea of restricting sales to players of a legal gambling age.
