Born November 18, 1970, Peta grew up an army brat all over the pacific rim, spending several years in Papua New Guinea where her Australian father was stationed. She discovered at a young age a love of performing, in part to help her dealing with changing schools and being the odd one out growing up. She spent summers with her grandparents in Australia, and she remains to this day very close to her family. Before becoming an actress, Wilson worked as a model. However, performing is her first love. She moved to Los Angeles to study acting with Arthur Mendoza, a protege of Stella Adler. Wilson's credits include a bit part on Highlander: The Series, the films Loser, The Sadness of Sex, A Woman Undone, One of Our Own, and the forthcoming Mercy, co-starring Ellen Barkin, Julian Sands, and Wendy Crewson, directed by her longtime boyfriend Damian Harris. She also has a production company, Sweet Lip Productions, and is developing several projects, including Guns In The Night.
