So...
On the day before myself, my wife and son head back to Perth from Bali we go to the Oz consul and visa application center for advice (to no avail) and 3 working days before my daughter flies to Perth we got an email address and send what is basically a grovelling letter explaining again our situation emphasising the ties and personal situation including my 21 year old daughter potentially being stuck here in Bali on her own until the visa is granted.
Email sent at 3:30pm Perth and Bali time (5:30 already in Canberra), at 4:22pm local time she received the good news, RRV granted!!! The gods of Bali are on our side! And obviously they have some sway at immigration house
We came so, so close to changing application to WHV but resisted at the last minute too
Again a huge thank you for the sound advice received in the last few days, it was very much appreciated and swayed us to hold on
Application submitted 24 March ‘19 and granted 22 May ‘19
