Not a direct answer to the question, but
General Handbook 33.6.4 wrote:When a person moves from the ward for less than three months and plans to return, the membership record is kept in the ward.
You didn't say where she would eventually move to, but unless it's to be with here father, I'd keep her records for the month.
If you move them out, what's likely to happen is the Australia ward will eventually move her record back - but probably a month or more after she's already left. And then you're stuck not knowing where to send them.
Personally, I think you're better off hanging on to them so you remember to ask for the info before her final moveout.
