Present I'm working as a math academy instructor in Korea, and the biggest challenge in my life in Australia is English.

by any chance In neighborhoods with many Koreans, there are Korean-style math academies (offering Korean curriculum and Korean language classes). Is it well developed?

In fact I wonder if I have enough opportunities to work as a math instructor without any connections (instructor demand) I'm curious..

 

Or Is there a community where Korean-style math instructors are present?

again I wonder if many Korean families send their elementary school children to study rooms,

like this I'm curious if there are neighborhoods with clusters of academies and study rooms (like in Korea, cram school districts).
