Applied for 3x ETAs with them this morning. Email with data sent at 1049am, received response from DFAT at 1058am, followed by an email from our friendly ETA expert at 1111am indicating that 2x ETA approved but mine was rejected. Payment was requested for the two approved ones.
However, this rejection is probably due to my existing ETA on my old passport which is valid until Jan2019.
Rachel subsequently advised me to follow the instructions on the High Comm URL and this was just done a short while ago.
All in all, speedy response plus willing to assist when hit a snag. Just make sure you follow their published set of instructions, and of course, pay on time.
Keep it up Roos.
