Lights in the sky

From our 16th floor holiday unit on the Gold Coast, we are able to watch the planes swing around to line up to land at the Coolangatta airport. Last night, as I lay in bed, watching yet another set of lights in the starry night, I realised that this one didn't seem to be moving. Sure enough, over the course of the next (more than) twenty minutes, it continued to "hover" there. I tried to have a look through binoculars but the best I could make out was three lights - red, green and white. I couldn't tell how far away, or what, it was but it may be that I will check the local paper to see if there were any reports of UFOs in the night sky. If not, then I'm going with that it was a helicopter - although I had heard that most helicopter pilots would avoid prolonged hovering because it is dangerous.
