hey robb i live in australia and i dont think u have vistied some of our gr8 theme parks even thought we only have 3 good one and 1 big water park. These 3 are some of the best in the world:
1. Dreamworld, in dream world we have the tallest drop ride in the world..way better than blue fall! yes u heard me better then blue fall! also a coaster called cyclone that is a nice looping coaster
2. Warner Brothers Movie World, In this park we have one of the fastest coasters in the world reaching 100 km/hour in 2 seconds!!! Also another coaster called Lethal Weapon which one of those suspended ones. Plus those little novelties rides related to the loony tunes.
3.Sea World this park has one good coaster but is fun cause sometimes they have it run 50 times in a row!!! Plus gr8 dolphin shows and polar bears!!!
All i m saying is consider a trip to aussie theme parks cause even thought there arent 4 billion like america (so i exxagerated) we make up in quality!!! trust me it is worth it!!!
P.S cheers on this gr8 site and coverage of other theme parks in the world
