Perth Central Business District (CBD) is the best place to visit around Perth. During the night, it is the best thing to do- exploring the street, city and looking at all those beautiful rivers and colorful lighting. I had only witnessed it one time while returning back home on a car. On the daytime, I travel across the main part of the city from time to time not frequent.
It's always mesmerizing to watch all those beautiful buildings, tall skyscrapers and roads.
