Ferrario was born in Canberra, Australia to an Italian mother and English father . She is currently the face of a lingerie line by Dita Von Teese for Australian department store Myer, and has previously worked with Gok Wan for Target (Australia) and other Australian brands such as Sportsgirl and Berlei, overseas she has worked for Italian stores Fiorella Rubino, Flow clothing in Malaysia and Swimsuits For All. 
In 2012 Ferrario shaved her hair off to raise money and awareness for cancer, alopecia and trichotillomania. She then grabbed the attention of fashion photographer Peter Coulson who photographed Ferrario for his book In My Pants, a charitable publication to raise money and awareness for cancer and the Cancer Council (Australia).
In February 2015, Ferrario started a campaign with television presenter Ajay Rochester to end the use of the term "plus size" to describe models who are above a US dress size 4 by the modelling industry. Ferrario posted a picture with the caption "I am a model FULL STOP" with the hashtag "#droptheplus" which gained coverage in the media and was heavily discussed, with mixed, but mostly positive reactions, on social media and within the fashion industry.
In 2017 Stefania was amongst the four faces of Melbourne Fashion Week.
