Margot Robbie wants four children.

The 'Wolf of Wall Street' star - who was born in Queensland - is keen to stay in the US while her career blossoms, but she's convinced she'll return to her native country Australia when she has kids as she believes the relaxed lifestyle will be better for them.

Asked when she'll move back Down Under, Margot replied: ''Probably not for about 10 years, because I've got so much to do before then, but I really want to have four kids ... I'd love them to have adorable little American accents, but I do want to bring my kids up in Australia; it's such a good lifestyle.''

The 24-year-old actress shot to fame after starring as Leonardo Dicaprio's onscreen wife in the biographical drama last year and she admits she was concerned she wouldn't be able to progress further.

Speaking in the March issue of Australia's Vogue magazine, the blonde beauty explained: 'Wolf of Wall Street' was so insane and doing it was such a crazy, amazing experience. But once I'd done it, or while I was doing it even, I didn't see how I could possibly move things forward from that because that was just so incredible.''

However, Margot has since landed an upcoming role alongside Will Smith, 46, in the forthcoming American rom-com movie 'Focus.'

Speaking about her handsome co-star, she said: ''Will is the loveliest person. I'd heard he was the nicest guy ever, so funny, so professional, and I thought, ''He can't be that great,'' and then I got on set with him and I was like, 'You are that great, I want you to be president of the world because you are amazing!'
