Quigley Down Under (1990)

American sharpshooter Matt Quigley, known for his extraordinary long-range accuracy, answers an Australian rancher's ad seeking someone with his unique skills. But upon arriving, Quigley learns that the job isn’t about hunting dingoes, as he’d assumed—the ruthless landowner, Marston, wants him to kill Aboriginal Australians. Outraged, Quigley refuses and is left for dead in the Outback. As Marston’s men relentlessly hunt him, Quigley prepares to strikes back.
