(talking about compsci/it) past this i would highly recommend doing as much work experience/internships in your degree, im not sure how it works at unsw/usyd but at uts u can either do a bachelor of professional practice or somethin of that name and get a 9-12 month work experience built into the degree, or take an internship elective for a semester (so 6 months). i would really recommend maximising that especially in technology, as has been said it is so saturated now that you really need that to get your foot in the door, a bachelors simply doesnt cut it. im pretty sure usyd/unsw would have a similar internship elective/program, so if youre going there that could be a good idea.
