This's a pic I took when I came back Sydney from a month holiday. Look at the pic, you can the main CBD area as the background. Both sides are full of people on the pedestrian (probably you only can see left-hand side). The street is during construction at least few years.
Thing is changing every day, min and sec. The only thing does not change is "Sydney is always busy." This city will get better and better. The new Sydney will be shown up in a couple years.
