Just a reminder that the Melbourne Cup is not a National Holiday in Australia. It is a Holiday for Melbourne (and some parts of Victoria I believe). Other Victorian regions get their own “cup day” holiday.
However much of Australia has a long lunch, or even a party to watch the race. So there goes an afternoon of work in most places.
NSW-based filming is normally not affected by the Melbourne Cup.
Personally I’m Nup to the Cup guy. I don’t attend counter-programming as I think a boycott needs to not recognise the actual bloody event. I also don’t begrudge someone else’s decision to enjoy the event.
