Triangular UFO Caught On Night Vision On December 8 In Melbourne, Australia

I've watched this guy's video clips before and some of his captures are easily explainable....drones, aircraft, satellites or space junk. However, once in awhile he does capture something unusual and most times it's triangular in shape. On December 8, YouTube's "UFO Lou" caught another triangular shaped object, moving quickly with his P8079HP Night Vision Device. Kind of makes me want to build a night scope, to mount somehow on my Nikon Coolpix P900. Definitely some weird stuff flying overhead in our darkened skies.
