Is studying abroad in Asia worth it?

I'm a 20 year old Korean male in Australia. I recently travelled to Japan and Korea and realised how much more I like it over there (although there are some things I would definitely miss about Australia). So my question is, is it worth going on exchange to other Asian countries? I don't really want to go to Europe or America atm, although that is where a lot of my friends are going. Main concerns is costs and income source obviously. Curious to hear other people's experience.
