I was in melbourne last weeknd (with silverballfever) and this is what we found;
Airport - at international arrivals - Simpsons Pinball Party, South Park, Addams Family. $2 for 3 balls. All 3 had issues.
Casino - nothing and all the videogames/redemption machines/children drove me crazy
St Kilda - Apartment 23 had a Sopranos in good nick (though a little dirty). Prince of Wales had a Family Guy but didnt get time to play it. Pub at the end of Akland St had a Getaway in very good nick (though replay almost 200k)
