Study architecture abroad?

I am a graduate from University in South Korea, Majoring in Architecture. Now I am working in one architectural firm in south korea. I am thinking of my master degree in other countries but dont know where is the best place for my further education. I also still now sure if i should continue my major field or not. anyway, if i want to go for architecture degree where should i go? I am thinking of Australia and Europe. and how much should i save to spend for my living and education fees? Any chance to get scholarship from those school? or what should i prepare for it?
