Foreign Exchange is a television series produced by Southern Star in association with Irish public broadcaster RTÉ (Raidió Teilifís Éireann).

The series starred Lynn Styles as Hannah O'Flaherty, a feisty Irish girl, and Zachary Garred as Brett Miller, a sun-drenched Australian boy.

The series of 26 episodes was created by the Australian author John Rapsey and directed by Annie Murtagh-Monks and Gillian Reynolos.

Brett Miller and his family live underneath their restaurant, only to find a rock that opens a portal into the basement level of O'Keeffe's College, an Irish boarding school (which is in reality Castlehackett House, near Tuam, County Galway).

[1] There he unexpectedly bumps into Hannah O'Flaherty, a student from Galway, who is delighted to learn that when she turns a similar rock on her side of the portal, she can escape the grey and winter of Ireland to the sun and summer of Australia.
