The attraction launched within a month of the Australasian Premiere of Harry Potter and the Philosopher's Stone at Warner Bros. Movie World. In order to fully publicise their new attraction Movie World opened a Harry Potter Gift Shop on Main Street and had young staff members dressed as generic Hogwarts students walking around the park. These characters remained in Main Street until the closure of the exhibit in 2003.
The attraction was modified in mid-2002 to suit the second film, Harry Potter and the Chamber of Secrets. A few scenes slightly changed to suit the second instalment including the addition of a replica of Mr. Weasley's Flying Car.
Guests would queue at Platform 9 3/4 right alongside a recreation of the Hogwarts Express. The walk-through began by admitting small groups of guests into a small room with brick walls surrounding. Thanks to the magical expertise of the group's guide, the wall would magically slide away to reveal Diagon Alley. A similar scene appears in Harry Potter and the Philosopher's Stone. Guests were guided along Diagon Alley, with a quick stop at Ollivanders Wand Shop and into Harry's dormitory. Guests were then able to discover the art of sending an owl with a real life owl display.
