Quigley? Seen it once many many years ago. Can't really remember it, but good scenic filmwork from what I can recall.
The area I live in Sydney is very popular for TV and movie location shooting. The pub they made Priscilla, Queen of the Desert at, is just up the end of the street. Other movies shot around here are Billie's Holiday, Muriel's Wedding, and Strictly Ballroom. Fox studios is about 5 kms away, where they made Moulin Rouge, and curenlty, The Matrix II, and the new Star Wars movies are being made there too.
With a lot of Oz movies (outback stuff) you will recognise the same location for most of them. It is at a place called Silverton (bout 25kms out of Broken Hill). The only thing there is a pub!
The plains beyond Silverton.
This piece of road has been used in many movies. Not sure if Quigley was made there or not.
However, Silverton does have it's own railroad.
