wanna find a boarding school

My son loves green and animals, so we choose Australia
however, we never been in Australia, just knew aus by online,

Son now studying in Band 1C S.2, academic not bad, just he is not talkative

i would like him in a pure and nature but also good academic boarding school

Not a must with many Chinese
No boys school

Please help if any recommendations for your child is happy to study at.
