If you have the time, Yes.
Check out how to get to get UNSW on a daily basis, don't leave it till the O-week or Enrolment day. Because sometimes, depending on your luck, you may not always get there at the right time.
But, it's not compulsory of course! =) I can understand that you have nothing to do, if you're just heading to UNSW for the sake of knowing transportation...but a really important thing to check out is (This applies to med and non-med students as well) - PRINT out your course timetables (i.e. Say you had BIOS1101, MATH1031) add your required courses into MyUNSW Student Profile then go click Enroll. Next you should see a whole list of times + Location of Tuts/Lectures/Labs.
If via UNSW Portal you cannot see the Lecture/tutorial locations, go to UNSW's Online Handbook, and type your course number into Quick Search on left hand side, then once you find the course click Class Details, it should display a WHOLE list of tutorial/lecture/lab locations. This should somewhat give you an idea of where your classes are.
The main reason why you should do this is so that just in case you have a lecture from 9-10am, then a tutorial straight away, you will know whether its 5 minutes away from your lecture room or 20 mins...this is also the reason why some tuts you see on screen run at the same time (= it's a different locations on campus)
