I'm basically asking whether employers care about the uni you go to and your wam. I know that your wam has an affect but I know for a fact that unsw exams tend to be more difficult than other unis e.g. macquarie. Obviously higher difficulty exams mean lower wam and that's what I'm afraid will screw me over.
Generally speaking, employers don't care about your university. There are some exceptions to this (MBB and IB), but most modern organisations are more interested in other areas of your CV. The reason this myth continues to remain is because most people who secure graduate roles are from prestige unis. However, this is mainly because prestige unis tend to attract stronger, more serious talent. For example, the ATAR cutoff for UNSW Commerce is around 95, compared to say 60 for Notre Dame. ATAR might not be the best predictor of future success, but it would be fair to argue that the cutoffs ensure that UNSW has a stronger cohort versus ND. Consequentially, UNSW students perform better than ND students by virtue of their ability alone, not the unis prestige. However, it should be noted that top organisations focus their recruitment efforts and campaigns at the prestige unis due to the stronger cohorts which also adds to the overrepresentation.
