In 2015 Heathdale Christian College is offering four languages:
- Latin (Years 4 to 12 at Werribee);
- French (Prep, Year 1 and Years 5 to 12 at Werribee);
- Chinese (Years 5 to 12 at Werribee); and
- Indonesian (Prep to Year 6 at Melton).
As part of an extension to offerings in Modern Languages, it has been a Heathdale tradition to offer in-country excursions to both China and France. These excursions are open to students in Year 9 upwards as per the language they are studying.
Heathdale has connections with schools in these countries and these excursions have been most beneficial for all students, who have reaped many rewards both culturally and and linguistically.
