Zaetta was born to an Italian father and an Australian mother, and is the granddaughter of amateur botanist James Howard Browne.
[4] In 1999, Zaetta landed one of the six supporting roles opposite David Hasselhoff as Kendra the triathlete, in the short-lived Australian edition of Baywatch.
[6] Zaetta co-hosted Mission Implausible, Britain's Sky1 prime-time show, with Jason Plato, which found both hosts competing against each other in a series of challenges each week.
[10] In May 2011, Sydney-based author, Amanda Cole, issued Who Needs Prince Charming?, a self-realisation book for women, which collated contributions from 35 Australian women including Zaetta, Bianca Dye, Camilla Franks, Kathryn Eisman, Molly Contogeorge and Cindy Pan.
[12] Her first step into the Bollywood limelight was in Bunty Aur Babli in 2005, before winning a support role in Salaam Namaste which was shot in Melbourne, Australia later that same year.
This required her to learn fight sequences and perform wire work to display flying somersaults and mid-air kickboxing manoeuvres.
After the tour, accusations arose in the media that Zaetta had engaged in sexual relations with one of the Australian Special Air Service Regiment (SASR).
