SYDNEY, Nov 5 (Reuters) - Australia's internet watchdog

on Wednesday widened its world-first teen social media ban to

include Reddit ( RDDT ) and video live streaming platform Kick,

and said more sites could be added if their main role was to

enable online social interaction.

Australia will become the first country to fine social media

firms up to A$49.5 million ($32 million) if they fail to take

reasonable steps to block users aged under 16. The law will

become effective from December 10.

* The eSafety Commissioner on Wednesday urged tech firms to

continually assess whether they meet the definition of an

'age-restricted social media platform' when they introduce new

features or their primary usage changes.

* Discord, GitHub, LEGO Play, Roblox ( RBLX ), Steam and

Steam

Chat, Google Classroom, Messenger, Meta Platforms' ( META )

WhatsApp and YouTube Kids do not currently meet the criteria for

an age-restricted social media platform, the regulator said.

* Facebook, Instagram, Snapchat, Threads, TikTok,

X, and

Alphabet-owned YouTube have already been included in

the list.

* There will not be a static list of companies that are

age-restricted because of the fast-changing nature of

technology, eSafety said.

* When new tech platforms emerge or existing ones change

their

purposes, eSafety said it may reassess those services.

* "We will continue to take a whole of ecosystem approach,

but we

want to reinforce that just because a service is excluded, it

does not mean it is absolutely safe," eSafety Commissioner Julie

Inman Grant said in a statement.
