Ya I think it was after his graduation he said that in an interview that he would like to get out to Oz as he has family there.Powter going travelling? I believe I read comments from him during year saying as much?
I don't think he said when tho, I also vaguely remember in the interview he said he wants to settle in as a Dr first etc so we could be a few years off him going.
Every year in the off season tho Powters name is brought up as travelling/taking a year out or that he's injured etc
