At just 20 years old, Courtney Eaton has already had some pretty impressive doors swing open. The first one was when the former Perth model was picked by George Miller to star as one of his five beauties in the dystopian action thriller Mad Max: Fury Road - and lucky for her, the film was a worldwide critical smash, recently scoring 10 2016 Oscar nominations. The good fortune continued when Courtney caught the eye of Karl Lagerfeld, which led to walking the Cannes red carpet in Chanel and winning a coveted spot at the house's S/S '16 show. Even more recently, Courtney learnt a valuable social media lesson in dating former Disney star/musician Ross Lynch - watching her Instagram followers skyrocket after announcing their relationship.

And now, Courtney returns to her Australian roots by starring in Bonds' latest A/W '16 Sport campaign. We sat down with her to talk about her exciting new role as Youth Ambassador for the iconic Aussie brand and other exciting projects.

From Mad Max to Bonds girl: the rise of Courtney Eaton

You've done a lot of modelling before but now you've switched to acting - was it strange to go back to it for the Bonds campaign?
No, acting and modelling intertwine a bit, especially with things like magazine interviews and shoots. I haven't really stopped modelling in that sense, there's just less model and catalogue stuff. With acting, it comes with ambassador jobs and shoots, so they're similar.

What was your favourite part of shooting with Bonds?
I loved the [shoot] day - we ended up going down to Bondi. I hadn't been back in Australia for about a year, so being at a good beach with Aussies running around was great. It was also fun doing the video section of the shoot, they made me do push-ups and sit-ups, and by the end I was like, 'Ah, I need to work out more!'

Last year was huge for you! What films or projects do you have coming up?
I have [the film] Gods of Egypt coming out next month so I'll be busy doing press for that, and I have a few things in the works but I don't know if I can speak about them yet.

You're dating former Disney star turned R5 musician Ross Lynch, who has 2.5 million Instagram followers - what's it like to be with someone with that level of fame?
It's interesting - when fans first started finding out about us, my phone couldn't handle all the notifications coming in. He has such supportive fans and I think it's great. A few of his fans probably don't like me, but I think it's because they don't really know me. It's pretty crazy in this day and age, how you can keep up with people's personal lives through social media.

You also quickly gained a lot of followers on Instagram, that must have been strange! How have you coped with the sudden fame after Mad Max: Fury Road?
I still feel pretty normal and can go down to the store and buy things without being noticed. It hasn't really hit me much. I was 16-17 when I filmed Mad Max and I'm 20 now, so there's probably a height difference, plus I have a fringe now, which probably makes me less recognisable. When they think they recognise me I say, "I played the youngest sister in Mad Max" and they go "Oh wait! I do recognise you!"

You've been lucky to develop a relationship with Karl Lagerfeld and Chanel - can you tell us what Karl is like?
Yes, for red carpets and events, I love Chanel! Karl is pretty amazing, the things he can create. I really admire him.

What was it like attending the Chanel show last year and wearing the clothes?
It was insane. I knew the set would be out of this world and it was incredible. The clothes were amazing and it was great being in Paris too. Then after the show, seeing Karl, he looked so happy with everything.
