Is Csillam Australian? I want a specific answer, thank you.

When Daxian/Kloc-0 was 0/0 years old, his father immigrated to Australia, and he followed his father to Australia for several years. The so-called Australian citizenship was immigrated by Daxian's parents when he was a student, because he was going to study in Australia. However, all of us, including himself, agree that he is from China, and his name in his works is also a Hong Kong actor from China.
