The online platform will have to take steps to restrict their users to over-16s on December 10.
Twitch is the latest social media site to be included in the looming ban on younger teens, which comes into force on December 10.
eSafety has assessed Twitch as meeting the criteria for an "age-restricted social media platform", as online social interaction is its sole or main function.
Twitch is a platform most commonly used for livestreaming or posting content that enables users, including Australian children, to interact with others in relation to the content posted.

However, eSafety has found Pinterest to not meet the criteria, so it will not be subjected to the rules of the ban.
"While Pinterest enables some online social interaction, it is not the significant purpose. Pinterest is more commonly used by individuals collating images for inspiration and idea curation," eSafety said in a release.
Twitch will join Facebook, Instagram, Kick, Reddit, Snapchat, Threads, TikTok, X, and YouTube on the list of platforms affected by the online safety legislation.

From December 10, they will all have to take "reasonable steps" to prevent Australian children under the age of 16 from having accounts.
eSafety has said no further assessments of other platforms are planned before that date.
