How do I find a Japanese-speaking flatmate in a place where it is not frequently spoken? (say Sydney, Australia, but totally as a hypothetical example, because I don't want to be seen as spamming)
Do Japanese speakers typically use the internet for searching for accommodation, or do they use other means as well, such as printed Japanese language newspapers, advertising on notice boards in shopping centres, or word of mouth?
What are the most commonly used websites for accommodation? What are the most popular equivalents of easyroommate.com (dedicated to shared accommodation), and gumtree and craigslist (general purpose, but have substantive sections for accommodation)? (I'm asking here, rather than just typing クラシファイド or 売ります買います into google, because I don't know whether the first hits are the most popular, or whether it's just search engine optimization).
Also, for people from countries near Japan, such as South Korea, Taiwan and China, who have learnt enough English to live in an English-speaking country, how common is it that they know enough Japanese to be a useful language exchange partner for a beginner?
I checked whether Resources for learning Japanese has any information on this topic, and it doesn't. If my questions are better answered in chat, I'm fine with that as well. I'll also keep in mind not to assume that everyone looking for accommodation is interested in language exchange.
