Can you give a few clues? Mainly just frequency reductions, or route cancellations?
Is the delay from today (when you seem to know about these) simply because it takes time to work out exactly what the airline wants to achieve, as it has to closely examine booking trends?
QF's focus in announcing changes will probably be still international, with maybe a mention here or there of domestic if any routes are to be cancelled, and a percentage reduction figure in flights given as a one line item for domestic.
However, one thing that's seemingly stood out domestically thus far is that MEL - SYD (busiest and probably with the highest percentage of corporate traffic as a percentage of seats occupied for the east coast routes, not including west coast mining centre routes like Pt Hedland) has, even accounting for the greater number of flights normally scheduled, much higher flight cancellation numbers than #2 route SYD - BNE.
If anything, this seems even truer for VAd than it does for QFd. To me that's counter-intuitive because QFd has dominance in non-leisure flyers.
Maybe this greater rate of SYD - MEL (not SYD -BNE) cancellations is to be expected because to obtain the cheapest fare, many leisure travellers book a few weeks in advance, whereas lots of business travellers have to book close to date of travel due to meetings constantly changing, and hence latter in theory often pay higher fares, and are loved by airlines for so doing.
However to be definitive we'll have to wait for official government statistics that have a time lag.
