Correction: the Giant Drop cost A$14m.

r tower is 38 stories. now they say 40 with the top on.

Correction- 119 meters is as tall as a 39 storey high building and DID cost $12 mill Aus Dollars. It also pulls 4 g's and the top speed is 135kph.

Correction to you all. Giant Drop cost Dreamworld four million, the quote that everyone gets mixed up with was the one that Dreamworld quotes as "The Giant Drop would cost 12 million if it was a STAND ALONE attraction i.e. including the tower's actual cost and whatnot." And yes, Giant Drop is 39 stories, the tower stands at 126.5 metres (for those die hard fans who wanted to know) and the Tower of Terror can hit a maximum of 38 stories, the equivalent of 115m. So now you know.
