I'd sort of assumed that the non-operational bits of the State Government close down in the Christmas-New Year week, as the Feds do. (Nobody told me this the first year I was there, so I fronted up on the 27th and wondered why the place was deserted).
We're much too important to all go on holiday ;) It's nice and quiet here (until you get to the basement carpark, which is also the QV basement carpark, and it's full of bargain hunters).
