This approach makes you think that interviews may kick off in December, but it probably won't be until later in December. Given the month of December is cut short my the Christmas Period, I don't expect many interviews will be held prior to 2022. Certainly unlikley that the significant backlog gets cleared any time soon.
In reality, the actions appear to be focused on stopping criticism of the inability of the Sydney Consulate to continue services following the end of the NSW shutdown period rather than clearing the backlog of immigrants that are waiting for interviews.
