Quigley Down Under (1990)

Sharpshooter Matt Quigley is hired from America by an Australian rancher so he can shoot aborigines at a distance. Quigley takes exception to this and leaves. The rancher tries to kill him for refusing, and Quigley escapes into the brush with a woman he rescued from some of the rancher's men, and are helped by aborigines. Quigley returns the help, before going on to destroy all his enemies.
