Hi, I would encourage your husband to sort his trbwa as soon as he can. Mines was painless as I got mutual recognition as I was registered in Victoria but it seems like a real nightmare for some people.
I agree with the previous post that primary teaching jobs are tough to get. I arrived in sept but starting applying around July!! Huge amount of adverts but obviously a lot more teachers applying. Getting no after no is really tough but I guess that's what happens. I was really lucky and had a couple of offers. I got a years post through an appointment pool however I kept applying for permanent jobs and any in catholic schools as that's what I really wanted. I ended up getting one last week so all the hard work, constant knock backs has been worth it!! I also did some relief which was fine, just over $400 a day!! Plus no commitment of after school sports etc however, again as the previous post says you just don't know where u will end up! Suppose it all depends on your character.
Good of luck with it all.
