IPDB has it as only 375 made. http://www.ipdb.org/search.pl?any=hit+the+deck&search=Search+Database&searchtype=quick#1201
pretty rare I'd say especially for Australia.
I think it was Gottlieb's way to make it look a bit like a SS machine, blacked out reels with red segments,
as they were starting to get left behind    in the sales by not getting into Solid state machines as quick as the other manufacturers.
Looks an OK game but.
