They’re currently accomodating Daniel and his girlfriend in Sydney, apparently.
I don’t see how they will do the Finale with the finalists over Zoom. Definitely the previously evicted HMs will be, but the three finalists will almost certainly be in person. It just would be a lacklustre anticlimax. But I agree they’ll likely pre-record and film multiple endings now, not have it “live”.
They may end up having to do it via zoom. Who knows.
