I'm having trouble with Ｘからきた as a modifier...
I have heard people say 住んでいるのはどこ？ or something like that in order to say like, "where are you living?"... but what if someone wanted to say どこから来た？ in this manner? Like... "The country I came from is called Australia".
I can't say から来た国はオーストラリアという because you can't have から just sitting there like that... and you can't say 私が来た国はオーストラリアだ because you can't tell whether I'm saying I came from there or came to here (isolated from context).
Is there a way to fit から in there?
