To paint the picture for those who aren't familiar, the industry is enormous and, in NSW in particular, extremely powerful.
For a while (still? Not sure) in Brisbane, for example, you couldn't enter a bar after 1:30am unless it was a casino.
In NSW the sports clubs, of which there is one in every midsized town, have busses which circulate the retirement communities and bring the elderly to the poker machines for the day then drop them home again, broke. The busiest day is pension day.
Most small pubs have a larger and busier poker machine area than bar/beer garden area. Large "sports clubs" dedicate entire floors.
Australians lose the most money per capita to gambling by a significant margin.[1]
