Self-Exclusion as a Substitute for Mandatory Limits?

The Australian government is attempting to require that all players of "pokies" (electronic gaming machines) at clubs and pubs choose an expenditure limit. When they hit that limit, the players would have to wait (24 hours?) before they could resume gambling. The Australian loyal opposition is looking into alternative measures, including a national self-exclusion system. Perhaps more controversial is the possibility of third-party or family exclusions, where someone can be barred from gambling following an application not from the gambler him or herself, but from a close family member. Of course, family exclusions already exist in Singapore -- and in Australia! Another measure that the opposition is considering is to remove ATM access at gambling locales for would-be punters on the exclusion list. The inquiry by the Australian opposition is slated to be completed by the end of the month.
