The places to teach English is almost unlimited. You can even teach English in Australia if you want. Many students and working holiday makers do come to Australia to study for 1 year or more.

You could teach in Japan, Korea, China, Vietnam and the list goes on.

BUT, as you mentioned, you have one BIG limiting factor. Why would someone want to have you as a teacher if you are not native and you have admitted it yourself that your English still needs work on?

Why didn't you pursue studies to teach your own native language instead?

Just as a tip, places like China and Vietnam do take non-native English teachers sometimes, but it will depend on your accent, English level and past teaching experience.
