UFO or Bird?

Two astrophotographers found this image on their dashcam while driving in Australia. Our experts are unsure about what it is, but the consensus seems to be that it’s not a fast moving insect. If it is not an unknown, then it must be a bird. We have not been able to find any type of nightbird that would fly at high speed in a straight line like this in Australia. But if any of our Australian readers know different, we would be interested to hear from you. Please comment below.
