don't take this the wrong way folks but... we've seen this angst before (and for the record I am an August anniversary) and ALWAYS (since this had to be a thing) QF has come to the party in the most generous of ways. Just because they have not announced anything yet in public doesn't mean it won't happen.
The "St Mark" situation is actually a factor in favour for many as frustrating as it has been, along with the relatively late opening of QLD borders (Dec 17).
I am just sitting back and waiting for the reaction in a few weeks/month or whatever time when it's announced.
I mean look back and similar "they won't do it..." threads have been going on since the first extension and they have. And honestly it would be fair to make it a full year's extensions.
but also.. you know what? if it doesn't happen (which I doubt) then.. I'll live. As will everyone.
So try and relax.
QF will do whatever QF thinks will serve it best and I would put money on July-Dec extension.
My 47 cents worth. Happy New Year to all!
