I think there's always pieces of yourself that bleed into your character. That's inevitable. In some ways, we have similarities, but in other ways, we're completely different. It's hard to say because I'm an actor living in a world where we're all pretty privileged, and this guy is fighting for his life. They're very different circumstances. Within those circumstances, there are probably ways that we react to certain situations that are similar.

I think the most challenging aspect was keeping up the degree of physical fitness you need while filming a major leading role in a primetime U.S. series. You have very little time to sleep and eat, let alone train.

I hadn't been there [Comic-Con] before. It's pretty eye-opening, when you haven't been there, just with the sheer amount of fans that are there for different shows and films. It's like a big fan symposium, in a way, as well a way for film studios and television studios to really promote their product to their loyal audience base. It was an experience.

There are parliamentarians in Australia I really support. People through history, you know? Men like Ned Kelly in Australia who challenged ideals. Governor William McKell in Australia really set the tone of building a nation. The fundamentals of the country are built on what the governor McKell created. I think Sea Shepherd (Conservation Society) is a wonderful organization and I support what they do.

Doing all the rig work and the stunt work has actually been wonderful. It's a whole new skill set that I've learned that I'll get to take onto my next jobs. We get to do that all the time, the fighting and the learning new moves. It's quite exciting.

When I'm not working, I weight train three times a week and swim and surf as much as I can - in the summer, you usually find me in the water.

The White Ribbon Foundation is organization I support. They're bringing awareness of violence against women and I think it's important in our society.
