The teen, who cannot be publicly named, was well known in the international hacking community.
He pled guilty in Australian Childrens Court on Thursday, with sentencing set for next month.
They also seized two Apple laptops, along with a mobile phone and hard drive.
He then managed to use security keys that worked flawlessly to access Apples information.
He also allegedly had a look at customer accounts.
The teenager used a virtual private internet (VPN) to disguise his location.
It is unclear if any of the acquired data was forwarded to third parties.
However, it is understood that the teen hacker used WhatsApp to communicate his intrusion to others.
Apple has not yet commented on the case.
