So last week aussie stated they would not issue letters however i believe they are anyway.
Also forcing you (as a citizen) to cover your own quarantine was deemed illegal by i believe a qld court so no doubt you will be threatened to have to pay but ultimately won't have too.
NZ are issuing letters and have been a long time. Now they have closed all flights incl repatriation for 3 weeks so no going "home" anyway
generally in a group of say 6 people they aren't as bad as u think. There was one in Aussie offering flights melb to Syd for $800pp with a load of 6.. not bad considering say a wedding in syd and remove all the time delays of normal transport and a hotel vs up and back in a day on the jet
We are terrified dude. Gotta accept some of us were between visas at the worst time and now can't renew or know the future, with businesses and family here it's highly upsetting.
I do also understand your point that nothing is offical yet, however, not having a plan is a plan to fail
