Perhaps that's the way it's taught at Trinity College which Zhou Tong claims to attend.

In addition to its resident community of around 300 students and tutors of the university, Trinity includes three other major educational programs: Trinity College Foundation Studies, which prepares 700–800 international students for admission to the University of Melbourne annually
http://www.trinity.unimelb.edu.au/Founded in 1872 as the first residential college of the University of Melbourne, Trinity is a unique tertiary institution that provides a diverse range of high-quality academic programs for some 1500 talented students from across Australia and around the world.
The 1500 figure represents the 300 residences and the online students.

Phin, you're misunderstanding what the "colleges" within the old universities are.
Only a very small proportion of people - including overseas students - studying at Australian universities live on campus. Some universities don't even provide student accommodation. The fact that someone isn't one of the 300 residential students doesn't mean a person is a distance education or flexible delivery student. Foundation Studies students
aren't eligible to be residential students of the College.
Zhou may or may not be in Australia attending Trinity college, but the nature of Trinity college and its programmes neither supports nor refutes that possibility.
To be honest, if you're so damned sure that he's not in Australia, I'm not sure why you haven't asked him to take a photo of himself in front of a uniquely Melbourne landmark holding today's paper instead of trying to prove it through tenuous connections.
