"Stella is definitely wanting to pursue modelling and it's very difficult stage to work though because she's 12 but she looks like she's 16," the 40-year-old tells WHO.
Rama-Ellis says her first chid with ex Michael Klim, who has an Instagram account she keeps private, has done a few surfing shoots but doesn't want her involved in the fashion world just yet.
"I think I want her to have a better understanding of it and I've explained to her that it's more important to have a cause or to be a spokesperson and not just a pretty face.
"I've been trying to teach her that the idea of just being a model, you get washed up at such a young age, so she really needs to try and find a niche in the market somewhere which she can move with."
The mum-of-four admits that she would be a hands-on momager, making sure her daughter wasn't "used and abused".
Rama-Ellis is also mum to daughter Frankie, 7, and son Rocco, 10, with ex Klim. She recently welcomed a baby girl, Goldie, with husband Adam Ellis.
