Australian school schedule?

writing a story about a ten year old boy who spends his summer in australia. he’s going to be staying with his uncle and aunt, who have a son who’s a little older than he is (so his cousin’s about 12 ). but im guessing that although he’s on summer vacation (its winter in Oz.) his cousins will still be in school, right?

from around june-august
