As a kid, I never thought I'd be an actress. Never, ever, ever, no way. I was really shy - bordering on social disorder shy - and I was really academic.

All my family has very good mathematical abilities - like, so dorky. I was the dork then in school - on any maths exams I'd get 100%. I just knew how to do maths and most people would hate it, but for some reason it just came.

I don't like karaoke because the mics are always so worn out. The quality of the mics is such that you're always going (screaming) "Yeah, yeah!" and then you can't like it. It's like sometimes I'm too professional to get up and do it.

When I was just a girl in Sydney, no one thought, 'Oh, she's going to be a movie star.' No one. I had to get by with actual skill and talent.

I do notice that when I come in to meet casting people, they love that I'm Australian. Maybe it's our good work ethic.

As part of my job, I got malaria really badly and was put in intensive care, and I had a hallucination because they give you this cocktail of drugs to fix you so you don't die, and I had this hallucination that I was at the Oscars and I won and I was a really good actress, and it was so real that when I came out of the hospital, I started saying to people I'm going to become an actress.

Because of my filming commitments in America, you have to sign contracts where you can't change your physical appearance.
