The troubled Tongan schoolboy Jonah Takalua looks certain to join spoiled brat schoolgirl Ja'mie King in the ABC's highly anticipated new comedy series from writer/actor Chris Lilley.

The series, Ja'mie: Private School Girl, will focus on King but Jonah, arguably Lilley's strongest fictional creation to date, will also appear in the series, according to sources.

Although the new project is not being marketed as a direct sequel to Summer Heights High, the move would reunite two of that show's most popular characters.

Jonah Takalua was first introduced to viewers in Summer Heights High as the second youngest of five kids being raised by single dad Rocky Takalua (Tovia Matiasi).
