We’ve just checked the Nintendo 3DS eShop and Pokémon Sun and Pokémon Moon’s demos have not yet been released.
According to Nintendo of Europe, the demo will be available in all regions from October 18.
The Pokémon Sun and Pokémon Moon Special Demo Version will be available to download directly from Nintendo eShop or via the official Nintendo website starting from 18th October. The Special Demo Version introduces players to the Alola region and features Ash-Greninja, the Pokémon that appears alongside the hero Ash in the animated TV series Pokémon the Series: XYZ. Players will be able to transfer their Ash-Greninja from the Special Demo Version to their full version of Pokémon Sun or Pokémon Moon once the game launches on 23rd November.
Don't forget: a special demo of #PokemonSunMoon will be available from late morning on 18/10.

Since it’s already October 18 in Australia, 1:02 am AEDT at time of writing, we had hoped the demo would have gone live. Unfortunately, we’ll have to continue to wait.
Pokémon Sun and Pokémon Moon will be available for 3DS on November 18, 2016.
