I don't know about IB, but it should be the same.  And why just ANU?  Rankings are bullshit in the real working world - just come out of a reasonably reputable school with good results.
Furthermore, Canberra isn't the best place to study law, and ANU certainly isn't, unless you're into government/public policy law.  Truth be told TER of 95 is considered very low.  Sydney/UNSW/Melb/Monash have just as good programs (harder to get in too) and will be much easier to gain employment if you plan to work in Australia.  Perth has a shortage of lawyers and only has 2 universities offering law.  UWA is a pretty good school too.

legal practiotioners are on the SOL, namely barristers and solicitors, so u have to take the necessary qualifications in order to be considered such. Other legal practitioners without practicing certs will have to apply for assessment to see whether they have the required experience, qualifications to be considered as legal secretaries etc. Lawyers are however not on the MODL.

Simple terms:

You will get your PR by doing law.  However, you can only apply after becoming a solicitor, and in most cases this means doing your degree + 1 year of practical legal training.  Therefore, if you are doing a single 4 year degree, budget for 5 years expenses.

You will get a job in Australia if your grades are decent enough.  Since you want to do just law, your options really are Monash, UNSW, and perhaps Queensland since Sydney only has double degrees for undergrads and Melbourne have their strange new system which prolongs your study.  Between Monash/Melbourne & UNSW/Sydney, there really is no discrimination.  All have people in high places of the judiciary and the profession.  All are equal when you're looking for a job.  Melbourne & Sydney have the most jobs.  There's nothing in Canberra except government, and you can't work in government as a non-citizen.  I am suggesting that you do not study in one state then move because you will build your network in the state you have studied in, and the partners who interview you sometimes favour graduates from their own alma-matter.  Australia is also very state-centric.  Nobody here in Melbourne cares that ANU is 'ranked' higher than Melbourne/Monash, and I can assure you that graduates from there will not be preferenced just for that reason alone. 

Assuming you want to work in the large commercial firms, sell your soul to the firm and get $75k/year as your starting pay, both Melbourne and Sydney offer good opportunities.  Sydney has perhaps more banking, finance, M&A jobs, whereas Melbourne will have more employment, trade practices, IP work.  I was in your position about 6-7 years ago, I went to Monash, did my PR thing and am employed in a reputable mid-sized Melbourne firm now. 

Good luck.

I do not know the perception of Western Australian residents, but I suppose Murdoch is okay.  Canning college can get you to any university in Australia so don't restrict yourself to just Murdoch.  If you're practising in Perth, Murdoch would be fine, but if you moved interstate, you'd want to be from UWA simply because its more well known.

It depends on you.  If you want to practice in tax, you would need an accounting degree as well.  If you want to practise in IT law, having an IT background would be good.  But you don't yet know what you want to practise in, and sometimes you really don't get to choose - you just take whatever's on offer and hope to god you like it.  I don't think its important to have a second degree, but it would help you get your first job.  After that, I don't think it matters anymore.

I am practising in IP law.

whats about Malaysian Practicing law in UK? with their Bar as well.

oh how interesting. im planning to practice in melbourne as well, and so is my girlfriend who specializes in IP...hmmm!

from what i heard, oxbridge students do get preferences. besides, u will be entitled to the graduate work visa. my friend from cardiff just got a job in cardiff. she's a barrister.

As far as i know, those who wanna take BAR in the UK must be at least also employed in one of the firms in UK there in order to qualify for the BAR. And in UK, the firms of course would rather choose their own skin and colour 1st before us. As for grades i'm not sure but obviously it will also be an important factor ler
