Get a DTV instead, it also 5 years total and only cost $600, plus you can keep your money on your account rather than in a Thai bank acconut, well that is what I have done anyway😊

Yes but it will only be valid if you remain there, if you move to a different place and then go to immigration to extend you will need the TM30 to match where you are currently staying.

Followed this post by Emma as a guide, am also a Kiwi but been in Oz for about 6 months so had a bank statement and license for proof of address, attached the VEVO to the proof of address section using pdf merger. Uploaded my NZ company rego doc as well as my letter to work remotely. Had no further document requests, submitted 10pm Monday, had it approved by 10am Friday. Was super fast but I had absolutely everything attached and double checked it all before sending. Very easy. Glad I didn't follow other advice from sites saying you have to do it inNZ if you are an NZ company as it would have cost 2K.
