Primary school with french language (Brisbane)

Dear expats in Brisbane!
We are expat family and will be moving to Brisbane next month from DRC. Our 7yo boy had to start primary school here in Belgium school last year with zero knowledge of French and today its quite better than his english.
Ive been looking for school in Brisbane (public or private) that have bilingual education or french as second language to learn and don't have any luck yet. It would be really sad to loose all his french language skills.
IS anyone aware of such a school?
Thanks in advance,
Anna
