Apple One signed up with an Indian account, can not be family shared with AU account. The only thing that can be shared with AU account is iCloud storage.
It's a good deal for Apple TV / non Apple/ iPhone users to be able to access Apple Music, Apple Arcade, and Apple TV Plus, while also being able to share iCloud plus storage with their AU account.
Apple one is not available in Türkiye
Set up an Indian Apple ID using your AU number to verify.
Login into an iPhone, iPad, iPod touch, using an Indian Apple ID.
Buy Apple gift cards from Amazon India using your AU amazon account. Enter an Indian address (make sure indian address is selected, otherwise gift cards will show as out of stock) and use a virtual card from Wise.
Sign up to Apple One via settings.
Login on your Apple TV as a second account and enjoy all the services for a lesser price.
You can also share the iCloud store with your AU Apple ID via Family Sharing.

Dang that is cheap!
Was always against paying Apple one but now part of a shared family account with other ozb members. iCloud for photos is handy AF, and Apple Music is great. Arcade is still kinda soso.
