Gun-wielding thieves struck a Eumemmerring service station on Sunday 30 July.
Police said two men entered the business about 3.45pm, one carrying what was described as a long rifle.
They demanded the victim hand over money from the till and fled on foot to a court.
It’s believed they got into a silver hatch back and left the scene.
