Me and my wife where outside about half an hour ago, we live in the newer part of Bourke lands. It was around about 11:12 at night. We where outside having a drink when we heard a pulsating noise. We looked up and high above our house was a cigar shaped metallic object. It was only just below the cloud layer. It only seemed to make noise every time it pulsated. It seemed to be reflecting light even though there was no light at the time (seeing that it was late at night). When I say it pulsated it kind of went invisible. It pulsated around 12 times, around about the 12th time it pulsated it sped off, it went to fast to be any type of military aircraft that the Australian military would have.
