Edgar "Zonker" Harris, a citizen of the USA, wants to travel to Australia to study for a Masters of Suntanning at Slacker College, Humpty Doo, in the Northern Territory. (Assume that Slacker College's Masters of Suntanning course is, inexplicably enough, CRICOS-accredited.) Zonker obtained a BA from Walden College, Connecticut, USA, despite an academic record described by one potential employer as "catastrophic" (although Zonker prefers "colourful" or "remarkable").

Explain how Zonker will need to go about proving that he is a genuine applicant for entry and stay as a student.
