Thanks all for your replies. I will re-apply now that I am back in China. I thought being a fair-dinkum Aussie might help, seeing that there is a partner country connection there
I remember the BC in Thailand writing that the reason I was not given an interview was that my degree was old (1981) and because I only have a TEFL certificate and no other degree or Masters, so that I was underqualified compared to other applicants, though I have more than enough experience teaching adults.
Anyway, everything happens for a reason, so I will just try, try , try again and take note of your comments and advice.
