Digital media is a pretty popular course so I kinda doubt that there is one with UAI of 70s. And I think it is quite rare to find a uni that has an exact digital media course but do have similar things like B of Media or B of Media Communication. I guess, like how others say, UNSW and UTS is pretty good for those kinds of course. UNSW has a new course called B of Media. Check out its UAI for this year. I think you can also learn about digital media thought studying B of Advertising or just B of Communication.. You can always go to TAFE or institutions that are strong at digital media, such as Billy Blue and then move to uni next year.
