THE Victorian Attorney-General, Robert Clark, will lead a group to create national guidelines on social media after fears that comments on Facebook and Twitter could jeopardise the trial of the man accused of killing the ABC journalist Jill Meagher.

Australia's attorneys-general met in Brisbane yesterday - the day of Ms Meagher's funeral - to discuss social media's impact on the right to a fair trial.

The standing council on law and justice agreed to Mr Clark's proposal for a working group, which will comprise mainstream and social media representatives, judicial officers and police.

The group will make recommendations on how to regulate the spread of prejudicial material on social media, including warnings for users (which courts and police could issue on Facebook or Twitter) and protocols for social media companies.
