How are you feeling?
Kat: I think I was a bit disappointed as I wanted to make the top four, but at the same time making the top six is a huge achievement. I was so close, but I'm proud of myself.

BJ: I feel good. I feel excited. I think I was ready to go. Of course I the back of my head I wanted to make it to the top four, but my body was definitely ready to go.

What did you get up to once the show was over?

Kat: Me, BJ and the majority of the top 20 went out to have a little celebratory drink!

Kat, you turned 18 recently. How did you celebrate?

Yes, I turned 18 in January. I went to dinner at [Sydney's] Favela with my family and friends and then we all hit Sapphire nightclub. I got lots of perfume and jewellery and clothes and money. It was great!

Do you feel different having turned 18?

I didn't at first. I still felt really young. But because I've had to live on my own during the show, I feel like I've matured a lot and finally feel different. I still live at home with my parents but for the last couple of months I've been rooming with Amy, so I've had to learn how to wash my own clothes and cook my own food. Now I can help mum out heaps! Amy is the bomb! She helped me learn how to do all those domestic things.

BJ, you were away for six months last year in Korea performing in the musical Cats. What did that teach you?

BJ: It was really fun. It taught me how to be independent, because I still live with my mum, Gemma. She is very proud of me! That was the first thing she said when I saw her last night!

We hear you get really hyperactive. Did that happen during the show?

I do! I get so hypo, especially when I'm excited. There's only one way I can relax and that's by listening to music. I love lyrical music, like slow hip hop, so if I was stressed out or excited I'd just stay in my room and put my music on so I wouldn't annoy Amy.

Who did you see as your biggest threat during the competition?
Kat: I never really compared myself to anyone. I'm my biggest critic. I did surprise myself though. There's no way I thought I'd make it to the top six. I wasn't even going to audition for the show, but the day before I got butterflies and told my mum I had a good feeling about it. So I went for it and to make the top 20 is just the biggest achievement!

BJ: Myself! Everyone's different. Even when it got to the final six there was no sense of competition. All the guys are really, really close. We shared a tight bond, so there was no bitterness at all.

BJ, who did you get closest to?

BJ: Stephen is one of my best friends as well as my business partner, but also Tim, Charles and I got really close because we share the same sense of humour.

What's your sense of humour like?

BJ: We're just stupid, and we take things too far to the point of ridiculous! There were some very silly things happening back stage. For instance, Ben created an alter ego called Krumpzilla. Every now and then would start roaring and going crazy. One day he went crazy in the green room and throwing things, like bananas, and tipping bins over. We were all losing it on the floor. You absolutely lose it because you're at point of exhaustion, and the pressure sends you a bit loopy as well.

What was the toughest part of this experience?

BJ: Working at your peak without any sleep. For instance, Tuesdays and Wednesdays we started at 7.15am and didn't finish until 11pm. We were dancing all day; even at lunch we were eating whilst getting our wardrobe fitted. It becomes your life and I absolutely loved it but now I'm ready move on.

What was your favourite dance?

Kat: I never thought I could do ballroom! I shocked myself a lot, but my favourite was the tango! I felt like a completely different person with the short wig and little beauty mark. It completely transformed me. I felt like Maria from West Side Story.

How did you feel wearing those skimpy stage costumes?

Kat: Oh my God, I feel so much more fit from all the dancing. I've lost a bit of weight and toned up a little bit. I felt really good.

What's next?
Kat: I'm a singer as well as a dancer, so I'm going to be working on my music. My style is pop/RnB. I'm doing some writing, working with my producer, and getting some tunes down. I have also filmed my first feature film, The Combination, which is out at the moment. It's about Lebanese and Australian rivalry. It's a bit of a rough film actually. The moral of the story is don't judge a book by its cover. I play a Greek girl called Anna, who is the girlfriend of the lead boy in the Australian gang. I pretty much start conflict between the two gangs, because the leader of the Lebanese-Australian gang falls in love with me. It was a really intense film and it was great and I had a lot of fun.

BJ: I've got a business called A-Live Entertainment which I run with Stephen Tannos from this series, and Hilton Dennis from last year, who I went to high school with. We're a one-stop entertainment shop. We put on workshops to teach kids, do corporate packages and put on live stage shows.

What comes first for you: dance, music or film?

They're all equal. I started dancing when I was four so that's definitely my security blanket, but I would love to do another feature film and music just lives inside of me.

What about time for love? Kat, there are rumours you are dating Home & Away's Lincoln Lewis!

Kat: [Laughs]. I'll just say I'm single. But yes I know him; I'm very close to Lincoln.

What about you, BJ? You were single going in to the competition. Are you looking for anyone special?

BJ: Well, my fan base grew a lot from the competition and I appreciate it a lot. It means a lot to me that people are accepting what I do. But I'm not looking for anyone special at the moment. I'm looking for a good time, and I really just want to chill out a bit now.

Who should win?
Kat: I would love for Amy to win. I think she's an incredible performer and she's very humble.
BJ: On the basis of the votes so far, I think Charlie is going to win. But I kind of want a girl to win and I think both girls would bring something different to the American show, which is really important.
