No, I'm not. The key word is "prolonged" which you said was 1 year. So, fly back to Oz, put your papers in, get approved, fly back to Thailand, fly back to Oz within 12 months, fly out again, and fly back to Oz within the second 12 month period and you have qualified for portability.
Based on the information in your previous post, this can be done. It either can be, or it can't be. Which one is it?
