DTV approved just now! Canberra, Australia Consulate.
Thank you to a few anonymous posters for their advice, I was considering just using an agent and doing the soft power route even though I am self employed - until reading their posts and I am very glad I did it myself! Super super easy. Had everything ready before I started (took me maybe an hour to prepare) and uploaded and submitted the application within 30 mins.
Type - Business Owner/director
Submitted: 12th Feb
Additional documents requested: 14th Feb they asked for proof of financials of the 500k thb, strangely I had already uploaded 2 different screenshots including a bank statement, but it seems they preferred a proof of balance letter from my bank which only showed the amount on that date, in AUD. I also showed well over the 500k minimum on all 3 screenshots.
