It took officers about an hour to get the unnamed man off of the top of the building while tourists watched the scene unfold and took pictures.
"He was yelling out 'where's my wallet?'" a witness told News.com.au. Witnesses also said the man "pulled a beer out of his pants and has been pacing up and down."
Police eventually used ropes to get the man off of the building
People have climbed the building in the past in protest, but police do not believe this was a protest climb.
"A drunken guy just decided to go up the sails," an officer told the Daily Telegraph.
