We are sorry about the error message you are seeing when you try to start the game.
This is most likely because you are trying to login to the game with an account that isn’t registered on the Australian servers. Since the game is only released in Australia, you need to be located in Australia and create a new account on those servers.
If you have troubles accessing the game from Australia, please contact our support team at here!
We look forward to releasing the app to other countries as soon as we can!
