In 2012, Ireland received the regular role of Liz Birdsworth on Australian prison drama series "Wentworth", a reimagining of the cult classic series "Prisoner" ("Prisoner: Cell Block H") which aired on Network Ten from 1979 to 1986. "Wentworth" went to air on SoHo in mid-2013. Ireland has so far appeared as a regular in all three seasons, as a prisoner who gives peer support to her fellow inmates. Her character name is that of the original "Prisoner" character Lizzie Birdsworth, although Ireland plays a completely different character role to that of Sheila Florance's character, they do however share a similarity as Liz is a functioning alcoholic, Ireland would later exit the series in season 7. After leaving Wentworth Celia joined the filming of Five Bedrooms and Total Control.
