We are not under attack. The RAAF are conducting exercises around the Upper Hunter over the next two weeks.
There will be increased jets, flying lower than normal. As well there will be personel on the ground. Travelling mainly, around the towns of Merriwa and Sandy Hollow.
Jets will continue flying up to 10pm, or if you prefer. 2200 hours.
These exercises are to train, both pilots and ground staff for deployment to the Middle East in the future.
So if you see any different behaviour, or activity. It is more than likely the defense force, training.
