I caught a UFO today with erratic movements

The UFO makes a big movement at 1:30 and looked to be rotating while stationary and moving randomly to the left and right.

This was spotted today at 4:48pm in St Clair, Australia while I was working outside and helping my mum clean the pool. We both caught the shiny object a few minutes before and it disappeared but reappeared around 10 minutes later and I got to capture this before my phone ran out of space, by the time I managed to make space it was gone. This is a 4K video shot at 60 fps on my iPhone Pro.
