It's not actually related to the review into online gambling from 2023, but your comment reminds me of the pokies issue. We're constantly told that pubs and clubs have to be allowed to have pokies, because otherwise they'd go out of business and lose jobs! Never mind the fact that things seem to work completely fine in Western Australia. They worked fine in Queensland (with the exception of some people nipping over the border to Tweed) until 1992. And they work fine in the entire rest of the world that largely don't permit rampant pokies in non-gambling venues.
Sure, it would be a problem to remove something they've been reliant on for so long overnight. But a gradual, phased reduction of pokies in pubs and clubs on a clear timetable would certainly not be harmful.
