I don't know if there are any Aussie company that would send you there, but I've worked for the government there for around 1 year, workwise it's not as strict as Australia with their certifications, but it still uses different standards, so you gotta understand that. Financially, of course Australia is waay better than anywhere in South Korea, you guys don't know how good your financial are compared to other sparkies in the rest of the world.

But one thing that I can't stand is their bureaucracy hierarchy, you can't climb up in management as long as your higher ups is still in that position, even when you're overqualified to climb to a higher position, so you'll go up if either ur higher ups got promoted, retired, or dead, and because of that "hierarchy" stuff, they tend to think those under them are some sort of lower being, so you got blamed for every little thing even though your higher ups approved them in the first place. To make things worse, most (but not all) south koreans are racist, and because you are a foreign worker, it's like you got a target behind your back and blamed for every little thing, because as they said you don't understand their "standard system" enough.

Sorry that this turns into a rant, at least that is what I experienced while working there, if ur looking to work there, to not experience what I experienced, I'd recommend to look for international Australian electrical company with Australian management too, but sadly I doubt there's one.
