Isabel (On working with the rest of the cast of Home and Away): It's been so great. Everyone has been really welcoming. All the cast and crew are really down to earth people because there are a lot of kids in the cast. It was lovely to meet some nice friends, especially not knowing anyone in Sydney.
Isabel: I play Tasha Andrews. My character is quite an unusual girl. She's a bit of a Jane Doe, a mystery girl. She's discovered the beach and no one knows who she is or where she's from. It's all quite bizarre how she just turns up and as the storyline unfolds it's revealed she's a very withdrawn, naive, fearful kind of character, nearly animalistic. She's got these tribal instincts and she has aggressive outbursts like she's had some sort of trauma. No one knows where her parents are and no one can understand her because she speaks pig Latin, which is like a coded language.
Isabel: Well, the best piece of fashion advice, I gave someone would be: Be individual and wear what suits you and what you like!
Isabel: (Favourite fashion labels) I like unique clothing with beading and usually opt for more soft, flowing styles for example, Peace Angels. But I usually just wear jeans or whatever is the most comfortable.
Isabel: (on nicknames) I have like so many cool and funky nicknames. My sister tends to call me Belle. I love it when my friends call me Izzy. But, my favourite nickname is Isabella.
Isabel:(Getting the role on Home and Away) I felt so surprised when I got the role. I kept asking myself, "Why me?" I was so blessed to be in that position.
Isabel: I am totally addicted to natural beauty products. I like to look natural and radiant. So my best beauty tip is start on the inside. Make sure to eat healthy and drink plenty of water.
Isabel: (Your other talents) I love art.I always loved creative art-all of those arty subjects at school.Also music-I love guitar and I've had singing lessons. I'm now learning to skateboard and I am learning some moves now. I have also never been surfing, but I want to.
Isabel: (revealing why she chose to pose for photos in "FHM" magazine) I agreed to do it because I was able to handpick the photographer and the location and was able to control what the finished product would look like. [Acclaimed fashion photographer] Nick Leary took the shots, and the end result is no different to how a Vogue shoot would look.
Isabel: (on her future) Film (is my focus), but I want to try all different mediums. I have really had a lot of time to think about what I want and Home and Away was a wonderful learning experience, but it was a lot of pressure for a young person straight from school. Acting is what I love, so film and theatre is what I want to do now.
Isabel: (on her self-promotion tour of London) I auditioned for lots of different projects, all grass roots at the moment, so I can't really speak about them, but I met with lots of agents, including Kate Winslet's. She (Winslet) actually called when I was in the meeting. She was flying out to the Oscars the next day. It was all so surreal.
