I am here in pp and i hear it here. I think they might be working over at the landings over here as there is 1 barge out back with it looks to be huge rocks on it.
I have heard it the past few days. its like boom boom ( brief 3 sec pause ) boom . And I am in Sandgates area . Cant be missle testing or anything because its way to close and they dont sound like that . hummm
