I think it's a possibility. The boarders are closed. We on this thread haven't got an exemption, if they grant us a visa, we have an exemption, thus laying more pressure on their isolation system, of which they have just capped the incoming flight numbers to deal with, as the quarantine hotels cannot handle it & cases seem to be a source from these.
If you look at the 4 part phased opening that was recently posted by the Government, things are going to move very slowly.
Non of us have a crystal ball, I challenge any agent, forum made agent or anyone for that matter, to tell me they know whats going to happen, its just too difficult to say.
Just stay positive & save.
