Nathalie was born in Peru to an Argentinian father and a Peruvian mother, and her family relocated to Australia when she was still a child. The family put roots down in Sydney, and Nathalie noted that she didn't grow up with people with similar backgrounds. 

Nathalie opened up about her upbringing in an interview with NBC News.

"It was not like growing up Latino in the United States. Once a year there would be a Latin American festival and we would never miss it because it’d be my one chance to eat empanadas and hear Spanish being spoken and watch people dance salsa," she said. 

As far as how her relationship with her parents is, the actress explained that her mother pushed her hard to succeed. That's why she connected so much to the Garcia family on The Baker and the Beauty. 

"I didn't really have a great stable family background, so they've [the Garcia family] kind of helped me heal my wounds around love and family," she said.

Nathalie returned to South America when she turned 16. It was the first time she had been there since her family's move. She said that the trip encouraged her to embrace her roots.

"I definitely feel a deep sense of responsibility to my lineage, especially coming from Perú. I'm so lucky to have that ancestry. My grandmother still speaks Quechua, the language of the Incas, so I’m very connected to my indigenous Latin America side, even though my Spanish is más o menos (more or less)," she explained to NBC News.
