That would be about the time I woke with a start! Straight over my house (sounded like it) - Little build up...just whooshka! I sleepily lifted my fist "Air support!" And went back to sleep...I was up in time for the Gallipoli and Villas-Bretenuex (VB) dawn services...
Seemed to catch everyone out. And the timing was publicised prior. Even the abc didn’t get it on the live stream. Only talked about it after the fade. I knew it was coming so I was prepared. But it was about 2 minutes late.
