You talk about a lecturer who is based at one University campus giving lectures to other campuses
This is a scenario where a lecturer is based in a state 2500 km away from Griffith , where Griffith as no presence , beaming lectures back to Qld. I would say that would be highly unusual in the Aust University context.
How many full time lecturers do Melb / Monash / Deakin have that are based somewhere else in Australia - zero I would suggest.
The students clearly miss out on having someone who is collecting a full time wage from being around the aviation department. Available for extra time outside of tutorials , the casual chats in corridor , attending lab work/ functions. Able to drop in to their office at a whim with queries or ideas.
In other words the person just not being available for the normal student/staff interaction (& availability) that is typical of normal uni courses at normal Australian universities.
