Note that we can't guarantee it can be installed safely. At least I have been playing it without any problem on my phone.
Soft-launch in Australia
Animal Crossing mobile should be available on both iOS and Android. As reference, Super Mario Run and Fire Emblem Heroes, games that were developed by Nintendo and DeNA, are available on these platforms (Super Mario Run become available on March 2017).

Hello!!! I can't run the game in my iPhone. I downloaded it in the appstore and its crashing! Argggh! anyone?
If you are using a jailbroken iPhone, you can't run the game even you downloaded it from the App Store with an AU Apple ID. Since the game is online, they can detect if you are using a modified system. Try using tsprotector+ from Cydia.
