Ultra I am sure that your academic subjects at UNSW were delivered by full time academics (lecturers or above) who are employed by the Kensingon campus. They weren't beamed in online by someone who is employed full time by UNSW yet lives in Broome - which is what Griff Avn are effectively doing
Actually, one of the lecturers works full time at my current place of employment, and was running one of the subject i was doing at UNSW.. the UNSW work wasnt his full time profession..
from my uni experiences, what Griffith Uni is doing is not that unusual, not common, granted, but not unusual either.
