The intended effect of this persuasive technique in this article is to get Australians to stay away from using American vocabulary instead of their own.  It is intended to persuade them to, as the author says, "speak Australian."

The author argues that something is lost and Australian culture and society are degraded when Australians use too many American words and phrases.  He argues that Australian values are being replaced with American ones.  He uses subtle and not so subtle appeals to patriotism and nationalism to encourage Australians to stop using American words so that they can preserve their own, unique culture and society .
