The replica of the historic facade will include statues of Scottish heroes Robert the Bruce and William Wallace.

It will be shipped in pieces to Melbourne’s Etihad stadium, next February.

Performers will enter the stadium by crossing the drawbridge, just as they do in Edinburgh.

Brigadier David Allfrey, the Tattoo’s chief executive and producer, said shipping over and assembling the replica of the historic fortress, which has dominated Edinburgh’s skyline for centuries, is “a huge job”.

“When people see it, they will be absolutely astounded,” he said.

It will be so authentic that “people will be able to go up and touch it and wonder if it’s made of stone”.
