What should I do about my Psycho strata-neighbour (NSW, Australia) repeatedly trespassing and harassing me?

You need to go back to your original reference and look two paragraphs before - STRATA titles have additional requirements - you must adhear to their rules even if they override (in reducing the times noise is permitted) the state laws. You have more restrictions on noise when living in a strata facility than if you were living in three separate houses.
