She's even thinking if she should start to apply for Australian citizenship? She's lived here for years as permanent resident, any difference in an overseas job market, with Chinese passport + Australian teaching credentials?

I think she's going to do a Master of teaching (secondary) with Maths and Chinese as her two teaching areas.

Thanks for replies. As everyone suggested, it is not the best option for us to go overseas currently... Maybe wait till my wife gets certified. She's Chinese and she's considering to do a Master of teaching (Early childhood & primary). A teaching couple two years later..

Yeah I have to say I agree with you guys... As I said, after a quick research I don't feel it is very realistic according to my current qualifications... Currently we are saving around USD 40000/year(paying mortgage and wife works part-time). Just considering if there's anything better...

expect to save USD 40000/year...

Thanks guys.
I just did a quick search and found according to my current qualifications actually it's not so easy to get anything more than what I'm paid now if we go overseas...I have a house(mortgage) and 1 child 5 years old(so definitely need 100% tuition waive in the IS I will be teaching), and it probably will take some time for my wife to get a job locally. So economically we need something close to AUD 100k. We prefer to work overseas for several years save some money to pay off the mortgage and my daughter can have some diverse culture recognition. I teach Chinese(LOTE in Aus high school) and ESL.

Currently earning around Aud 80k teaching in a state high school. PGCE+3 years experience. Where shall I focus on if I want to save most. .. (not teaching couple, 1 child 5 years old)
