yes, yes, this is off topic, but i think mystikal already answered the OP quite well, essentially: ANU if you can afford it, Monash if you get into it, and Melbourne if you don't
I considered Law/Science because I wanted to apply for graduate medicine afterwards, and if I don't get in, I'll practice law
But I thought about it and I realised that it's not worth it 
So if I don't get into Med, I'll do Commerce/Law 
But law and science isn't unique they actually have a lot in common, like my favourite subjects are english and maths (which is a science kinda) and when I say they're similar, people disagree, but I personally think that they're fundamentally similar because you're using a means of expressing a viewpoint, whether it is to argue your view on a text or to argue a solution to a mathematical problem, both require analytical thinking and elements of creativeness and most of all, both are subjects where you can really think
(unlike subjects where you rote learn
)
A few things: don't that this personally, i''ve just been going out of my mind writing math notes for connect and need a good solid argumentative paragraph:
Sigh, i really *raised eyebrow* at people that do the whole "i'm going to do med or law" because frankly they are more or less polar opposites. Med requires being passionate about the body, and going crazily in depth to the anatomy of the body and the many many functions. It is not something you jump into for the hell of it, jsut like Law. Law requires a very different school of thought. Really apart from the fact that both require a *shite*load of work their matter is completely different. Very few if any have an innate aptitude for both, i.e. pretty much NO ONE thinks both genetics AND our contract law are amazing fascinating. Frankly, i think that anyone that has these in their course preferences has not put enough thought into what they really like and are most likely of a.... certain ethnicity... It is pretty much the ridiculous notion of wanting to go into something prestigious because it makes 'use' of your intelligence and what you can be good rather than making use of your passion what what you like doing.
In terms of the similarity between law and science i would have to disagree again. I would also like to take this opportunity to point out that maths is not quite a science more of the language of science, granted that maths and law do have a..... small degree so similarity as both are related to reasoning, but law really is not about reasoning so much as having masses of research into the best precedents/most appropriate law, sure presenting the arguments requires a degree of logic, but not really the kind that you would use within math to do a proof, and even less to the type of thinking required in other sciences with chem and biology where the most problem solving you do it stoich which doesn't exactly require an amazing amount of problem solving.
Also in terms of rote learning, in both law and med there is shit load of sheer information you just have to memorize, no doubt a fair bit of conceptual understand is also required but you will no doubt be doing a good chunk of going over and over information to remember it which by definition is rote learning. Also lets face it by the time you get to the english exam 90% of the people who get above 45 will have written a very similar essay before and gone over the idea and the evidence they will use many times over... hardly formulating amazing ideas for the first time in the exam using your creativity but more regurgitating what you've learnt and perfected, hello again rote learning. (yes. this was exactly what i did, and i am horrible at english yet managed to 'do well')
Having said that:
1) There was a rather interesting speech given by the chief justice of the high court of austral who himself did a science degree and law degree. The merit and usefulness of the science degree (physics) in terms of his career was more the knowledge rather then the 'way of thinking' that his science degree gave him however
