Show genuine interest in the field. (admittedly this is hard to fake, but I'm guessing you are into it so will be OK)
Make sure you've read in depth into what areas the institution researches. Read around those areas, be prepared to discuss it, particularly future directions in those fields. If you know who is interviewing you, google scholar search them (scholar.google.com) and read some of their papers. Don't be pushy about it, but try and have an insight/opinion on the areas of biology that are important to that Insitutue, basically.

Also what Shambles said.
I'm sitting here in my office in a Tshirt, jeans with baby sick on, and I haven't shaved in weeks and, y'know, I'm successful and good at this stuff.

You should be able to absolutely breeze it.

I have no interview appropriate clothes. Need to go shopping.
all the ones I have either need a new shirt/blazer, or are skirts (which means my foot tattoo will be visible and I don't want that).

Why not?
I'm not sure that would make the slightest bit of difference, but it's up to you of course. You need to balance being dressed fairly smartly, of course, but with feeling comfortable. Don't wear something you'd never consider wearing, you'll feel out of place and it'll show.

Remember, you interviewing for an internship in a research group, not a bank. Don't dress like a beach bum, sure, but equally don't dress like some power lawyer.

I dunno, I just don't usually have it on display, and I have a feeling that if someone doesn't like tattoos is on the interview panel and they see it, then it might be a little flag against me or something.
I was just thinking nice pants and shirt, but it's getting very cold here now, so will need a jacket or a coat is all.

I would suggest showing the interview panel
Your skiddies will be a bigger issue than a small tatt.

Proud to say I've not had skiddies since I was completed Potty-training as an infant.

thank you.
I'm very interested, the problem is that this internship is run through Melbourne University who liase with about 6 different institutions, so, potentially I could get placed at any one of them. I do have some say where I want to go (the Baker Institute), but I have no idea if they'll listen or not. I have been told the name of one of the interviewers (a HR lady), but the other two are research scientists who have not been named,I presume so as to stop us from trying to play on their pride?

I'll definitely have a read up on some more papers though. :)

I wouldn't worry too much about the mystery interviewers.
You have to remember that the people who are looking are at least as keen as you are to find an appropriate person. They're not going to be a dick and turn the interview into a power game. And if they do then you'd be as well to tell them to fuck off straight away. The far more likely scenario is that they'll be charming and welcoming (give or take their natural academic autism) and give you a chance to show them what you're made of.

well if they display their academic autism I'll feel much more at ease...

Also, the most likely reason they aren't named
is not that they are being mysterious but more that they've no idea who will be around on the day. what with them being academics.
