Before Offspring, Barrington unsuccessfully auditioned for George Mason's role on Home and Away. "I knew I was too old for it, but it was great dipping my feet into the Aussie auditions, which led quickly to my role on Offspring."
Barrington is stoked with Kiwi actors' success over the ditch, citing Danielle Cormack's trailblazing roles in Underbelly and Wentworth as inspirational.
He said there was a "huge amount of digital auditioning going on by Kiwi actors, hence our growing success internationally".
