I agree with you, Brekkie. Making the announcement so late in the day and also on the eve of Eid at Adha (an important festival for the Muslim community) is quite irresponsible.
If the intent was to curb mixed families movement over this period, the announcement should have been made days ago. Not at the 11th hour.
That said, I think we are to deduce from the latest announcements that the spike in figures has been very recent and the data upon which the decision is based was only available yesterday afternoon.
In which case, we could conclude that the last minute announcement was unavoidable and necessary.
Irrespective, regular briefings (weekly or twice a week, as you say) would perhaps tailor the mindset.
