a few bets or a game of cards can be pretty fun

I must say, I have a much much more positive opinion of blackjack or poker than I do of sports betting—in fact, my opinion on those is basically neutral if not mildly positive—and I feel more positively towards sports betting than pokies. I'm not interested in banning any of those, just in decreasing their societal prevalence and in decreasing the amount the industry is profiting from their exploitation. It shouldn't be normal for kids to be exposed to gambling when they watch Friday Night Footy and start casually discussing the betting odds. The companies shouldn't be making massive profits by causing harm, without also being made to pay back to society in some way.

Yes, a bit of betting can be fun. So can drinking. And we have a pretty big excise on alcohol. Based on the numbers in this page, a case of 24 cans of beer has about $18 added to its price because of tax (and that's not even counting GST!). When that case probably costs less than $100, that means it's an over 20% tax. So "people should still be allowed to do it because it's a fun occasional thing" isn't a very strong argument against increasing tax on gambling.

I should probably admit though, I mainly included the tax thing so my comment flowed better and followed the "rule of 3". I would like to see it taxed more, that much is true. But I can't actually think how to practically institute such a tax, which I would rather were on the back-end, more similar to corporate taxes than to GST. The first thing I can think of would be to do it via council rates and zoning laws, but that would have the unfortunate effect of benefiting online gambling over casinos and (for now—though as I've said, I would like pokies outside of casinos to be banned) clubs/pubs, which isn't ideal either.

But regardless of the whole tax thing, for me the most important thing is by far the other two issues. Advertising should be outright banned, the same as smoking ads have been for a long time. And pokies should not be allowed to suck the life out of our local clubs and pubs. Australia has 20% of the poker machines in the entire world (despite about 0.5% of the world's population), and a massive 80% of pokies outside of casinos. That should be banned. If you want to play the pokies, you should go to a casino. The "clubs couldn't survive without pokies" bullshit needs to die. They do fine in Western Australia. They did fine in Queensland all the way up until the '90s. They do fine all over the rest of the world.
