I'm in UniMelb Arts and I can attest to the Ancient History Dept. being pretty good. History is a mixed bag but I know people who swear their lecturers are utter gods.
Would not recommend literature one bit. Very niche-y; most lecturers are dry morons who'd rather be teaching Art History or Sociology so prattle on about irrelevant stuff, and most tutors are condescending 20-somethings who are all high and mighty about that one thesis they wrote, and seem to think undergrads are incapable of holding pens let alone writing essays. There are a few diamonds in the rough (two good lecturers that I've come across so far) but really not much in the way of selling points. It also seems to be the easiest area for unis to make cuts to, so subjects are frequently appearing and disappearing which can kinda screw up planning your degree -.-
I've had fleeting affairs with the philosophy department and most of them seem alright - couple of standouts in 2nd year subjects especially. I've heard way more people praise the philo people at Monash, though it'd make a pretty solid major/minor anywhere really.
I know absolutely nothing about how Law works. All I've heard is that it's mega-competitive because you'll have more than half of the Commerce and Arts departments wanting to do the JD, so if might be worth having a back-up option.
If you're keen on Journalism, Melbourne have a good reputation for honours/post-grad Media Studies.
You don't want to do Media as an Undergrad thing though!! Luckily you're eligible for almost all of the post-grad subjects so long as you've got a BA (and sometimes they require you to have 'some background in the field' which usually just means you've done some electives if not an official Major/Minor.) The undergrad Media & Comms classes are kind of a waste unless you want to sit around talking about shitty reality T.V. shows and how they represent capitalist ideologies

In post-grad they actually let you experiment with media writing and forms, so presumably that's where the interesting stuff happens.
I know independence is a really appealing idea, but unless you're financially stable enough to venture out on your own, it might not be a great move. House prices and rent aren't all that reasonable in Victoria, but they're way worse in NSW, especially in the metropolitan areas.
Very few people I know will have moved out of home by the end of an undergrad degree; unless there are extenuating circumstances you'll probably be better off staying at home, earning heaps of money for the three or four years you're at uni, and then moving out/ interstate when you're comfortable.
Happy to answer questions about Melb Arts if you want
