wasn't it Jeff Kennett that legalised them in the 90's?.
No! For the sake of accuracy it was the Kirner government that legalised poker machines in 1992.
Personally, I find poker machines to be as boring as bat s**t and haven't played one since they had handles and were known as one armed bandits.
But ban them? Probably better to regulate as much as can be done to minimise the social harm. Unfortunately the government is addicted to the tax revenue they generate so don't hold your breath waiting for them to do anything.
