Yvonne Strahovski is an Australian actress. Born in Australia to Polish immigrant parents, Strahovski speaks Polish and English. After graduating from the University of Western Sydney, she featured in a number of Australian television shows before starring as Sarah Walker in the American television series Chuck.

Strahovski first started her career in Australia appearing in film and TV roles, including a turn on satirical show Double the Fist and a part as Freya Lewis in the Australian drama series headLand. She has also appeared in Channel Nine's Sea Patrol.

She sent in her audition tape for the show Chuck while in the United States auditioning for roles in other shows, namely NBC's 2007 series Bionic Woman. She sent in an audition tape while waiting to hear from the other two jobs. She was contacted by the producers of Chuck the next day to come in to "run lines" with Zachary Levi. The producers called her back a week later letting her know she had been cast as Sarah Walker. Six months later, she moved to the United States.

Strahovski speaks fluent Polish and employed it in a brief exchange with a colleague in the Chuck episode "Chuck Versus the Wookiee" and again during the character's return in "Chuck Versus the Three Words". She used it again in "Chuck Versus the Honeymooners". Although she portrays an American in the series, she briefly spoke in a "Hollywood" Australian accent in the episode "Chuck Versus The Ex".

Strahovski appears in Mass Effect Galaxy and Mass Effect 2 as the voice of Miranda Lawson. Strahovski had her face scanned and animated so she could portray Lawson in Mass Effect 2. Executive Producer of the series Casey Hudson has indirectly confirmed her return for Mass Effect 3, stating "every main character will be in there somewhere" though the size of her role has not been revealed. Strahovski voices Aya Brea in the English version of the Parasite Eve spinoff, The 3rd Birthday, which was released on March 2011 for the PlayStation Portable. She also appeared in a CollegeHumor sketch in April 2011, parodying the music styles of Katy Perry, Ke$ha, Lady Gaga.

Strahovski appears in the upcoming film The Killer Elite, alongside Jason Statham, Clive Owen and Robert De Niro. In May 2011, she joined the comedy My Mother's Curse, opposite Seth Rogen and Barbra Streisand.
