One of the problems here is that the ATIS does not seem to be updated at regular intervals, at major airports in OZ, and I must assume that YSSY is A major airport!!
It is not uncommon to receive the ATIS 200 miles out, and find the same ATIS current after 40 minutes on the ground.
If crew know that the ATIS is being updated every 30 minutes, (as happens at real airports O/S) they will look for it, even if there are no significant wx changes. The only time SYD changes its ATIS, seems to be when we are dictated to change runway and beat up someone else's back yard and land with maximum crosswind and least headwind.!!
