The Pinnie Parlour is assigned to history.
Finny was going to open something like one, but unfortunately the building caught fire before the place got a chance to open. Given the restoration standard of the machines, it may have worked as a venture, but I suspect more on the cafe side than through people pumping coin through the machines. We may never know. Would I have attended? Probably a couple of times a year, but I doubt more than that. You can play for free at the dealer showrooms and I have my own machines at home.
What will work, I believe, is Australia's own pinball museum. If you can hang out at a venue all day playing pinball from all eras instead of having to endure rollercoasters and similar rides, I know what I would choose!
