I filmed up to 10 flashing lights above the horizon on my iphone11 on the evening of thursday 20th aug 2020, at 6:17pm in wallsend nsw east coast australia looking north. both myself and wife watched all these light slowly ascend slightly into the sky as they flashed all over the place from left to right above normal street lights and houses in the distant sky. i believe it was either over wetlands national park or over the mountains far away in the distance. duration of this sighting was around 3 minutes before the flashing lights moved to the left and could no longer be visible. they also produced no sound that we could hear.
