Folks, To clarify my circumstances. Lodge my application late February 2021 and flew out of Oz on 19 March 2021. Harry is correct in stating to have all paperwork to hand, especially email granting permission to leave Oz. In your application ensure you state and evidence, ownership of property, rental agreements, length of previous residence in Thailand (enclose copy of visa stamps) etc. Driving Licence, copy of house book, medical record and so on. The application field is a max of 200 words which frankly is not enough. Hint....on your Stat Dec re undertaking to leave the country for 3 months or more that was item 10 on mine. 1 to 9 was all the info I did not have room for in the electronic application. Good luck.
