Last October the wife and I applied for Australian ETA via the app and it went through, payment processed and was granted. I printed the related emails just in case they were needed. This month we upgraded our phones and when I access the app it says "no applicants to display" and wants me to start new ETA. Apparently when everything from old phone was copied to new phone the Australian app information did not make it. Everything is fine with the New Zealand ETA information.
So my question is are the printed related emails sufficient or do we need to redo the Australian ETA over again (and pay again)?
Any suggestions greatly appreciated.
