Thanks KTE711!... we are going to try to apply for a 600. Hopefully with no NFS condition so we he can stay up to 6months. Hope everything goes well for all of us. =)Maybe to be safe just have him redo both before he leaves for Aus.
What temp visa is he travelling on? I'm going to have to do that too because we need to get our kids in school there. I applied April 2018 so I know we have a long wait... Ugh!
