No, not at 5. My 5yr old is well spoken, mature, independent and confident. But I wouldn't let her travel unaccompanied. There are way too many what if's and if something happened to her, I could never forgive myself. I don't think I could do it til she were around 8yrs old.

This is really where I am at I think.

The only alternative is to fly her over, drop her at airport with ex and fly home immediately. Then he can fly her back to Melbourne and drop her at the airport with me and fly home immediately himself.
