Remember This? Sydney Tower Spidermen (1987)

In 1997, Frenchman Alain Robert climbed up Sydney Tower. Robert is famous globally for climbing up skyscrapers or notable structures in cities without the aid of any climbing equipment. In addition to Sydney Tower, Robert scaled The Sydney Harbour Bridge in 2003, Aurora Place (2009) and the Lumiere Tower in Bathurst Street (2010). 

But did you know that a decade earlier (1987), there were two incidents that involved people climbing the tower

In February 1987, one individual managed to climb all the way to the top. The Daily Mirror referred to the person as a "human fly" and a "daredevil". They did use a rope to scale the tower.

Five months later, three men decided to climb up Sydney Tower, not for the sake of climbing, but rather to protest against nuclear arms. The banner was unfurled around halfway up the tower. They were arrested. Greenpeace accepted responsibility for the incident.
