You might just be able to make out Sydney Centrepoint Tower (to the right, behind those tree branches), one of the most recognisable landmarks of the city. The tower was built to withstand high speed winds up to 172 km/hr, and stands 304 m tall. Of course, from this angle, it doesn't look that impressive, but the view from the top is quite breathtaking, expanding seemingly forever in all directions! There's a revolving restaurant at the top, so you get to see the whole 360 degree view over dinner. One of these days, I will snap a shot of the tower from another angle (closer this time).
PS: This one's for you Eric!
