Australia's communications watchdog is investigating whether the broadcasting of the video footage of the Christchurch mosque shooting breached media rules.
The Australian Communications and Media Authority has written to national, commercial and subscription broadcasters asking for information on the nature, extent and timing of the broadcast of content relating to the attack which has left 50 people dead.
ACMA will also meet with broadcasters to discuss whether current rules are adequately protecting Australian audiences.
The regulator is concerned about content made available or linked to on broadcasters' websites.
But as this content is beyond ACMA's remit, it will talk to the Australian Press Council about reviewing it.
