Of course...not.
That confessions poster was a post-grad student. And is in a really shitty situation too. I think there are even more comments about international students hiring out ghost writers (one of the prices was like $430 for something worth 60-70...)
For Techniques our presentation is just between two people and youre marked on your own performance.
That's the way it should be marked! IRRC, my friend at RMIT said that they had a system which they had to log onto to submit their work and used to communicate so that if any issues should arise, those who did their part would not be dragged down. Do you know if UoM has such a system? I think it would solve a lot of problems.
I have a feeling those internationals who use ghost writers didn't get into UoM through their academics. It's really unfair to those who actually work
