i grew up in forster/tuncurry and i remember the large arcade just off the bridge end at tuncurry....gee, i hadnt even remembered it till i saw your post.
when i was about 18 yrs old (22 yrs ago) i did go in there, but not much, we were too busy chasing skirt, but it did have alot of pins and other stuff.

that arcade did shut about 1991 or 93. 
that guy still has a small operators business today ( i think he took it over from his dad) and has a few machines here and there in those country areas. u see him selling stuff on ebay and his ebay name is rodney something (bit of an unfriendly bastard).

glad u bought back the memories. small world huh.
