* DawsonCasting: Both averted and played straight. All actors were about the same age as their characters, but Leonard Fung was 15 while playing 10-year-old Sun.
* [[CaliforniaDoubling Poland Doubling]]: While the series take place in at least six parallel universe versions of Australia, only two were filmed there. Three Alt-Australias were filmed in Poland and one was filmed in [[CaliforniaDoubling China]].
* RealLifeWritesThePlot: If you pay attention to who is traveling where over the course of the series, you will realize that only Australian actors were flown to other countries, and more importantly that the plot is written so as to reduce the need to fly actors back and forth.
* ThrowItIn: The weather during shooting in China was poor, with foggy sky and almost constant raining. The producers decided to use it as form of EmpathicEnvironment - when Sharak takes over the Land of the Dragon Lord, everything is gloomy and dulled.
* UnintentionalPeriodPiece: To TheNineties. Just recall the girls shopping scene in the first series
