The only problem gambling that betting company's worry about is punters who win, losers are most welcome.
Short term gain for long term pain is the only way I see this turning out, Entain will entice geo blocking with a lump some that's very tempting, if they get the monopoly then you can take it ir leave it.
Most of the betting on TAB racing is on NZ racing, have you seen the size of the non commingled pools on lots of the lower class aussie racing?
No doubt the big racing in aussie is a exception, lots of interest in that and rightly so, the product is good.
I really can't see how this is any better than the present setup, everyone grizzles about the present lot but better the devil you know than the devil who's lurking.
Leave it to the experts they know what they are doing, supposedly.
