Australia’s Highest Post Box

On the top of Australia’s highest building, the Eureka Skydeck (nearly 300 m tall, 91 floors), is Australia’s highest post box. From here you can send letters all across the world. There is a small sense of irony with this box. On the top of the tower there is so many people that the phone reception is very minimal, so minimal you can barely send a text message. One of the only forms of communication freely available on the top of this feet of human engineering, is the old fashioned snail mail.
