The object is unidentified, as in no particular type of bird has been identified. Australia has owls, not sure why owls would not be candidates for night flyers.My position remains unchanged, "object unidentified".
Not sure if I will continue to participate. Thanks to all contributors.
Over what span of hours were the videos collected? I would suggest collecting video at dusk and dawn, to see if anything flies overhead that appears similar to these two objects. The lighter background sky at those times could make it easier to identify the objects.
One of the problems with reviewing classic UFO pictures is that what pictures we have are all we will ever have (unless someone invents a time machine). In this case you have the ability to collect more video and the ability to collect video under different conditions (background illumination) than the videos you have posted. More information is always nice.
