FACEBOOK wants access to Australia's sex offender registers to help it keep pedophiles and sex predators off its social networking site.

And Victorian Police Minister Bob Cameron says he is happy to discuss the idea, sending departmental officials to meet Facebook.

"I have asked my department to meet online social networking representatives to ensure that this issue is addressed," he said.

"I have asked my department to undertake work, including proposals for a national ban on child sex offenders accessing social networking sites where they can contact children."

Social networking giant Facebook, which has eight million Australian accounts among its 400 million accounts worldwide, is not actively lobbying for access to the sex offenders registers, which are held by each Australian state.

But in the US and parts of Canada, it is given access to the data on the sex offender registers and uses that information to track down sex offenders, disable their sites and ban them from opening new accounts.

Facebook's chief security officer Joe Sullivan said his company would co-operate with Australian authorities.

"We would welcome consideration of ways in which information about registered sex offenders can be securely shared with social networks- a model, widely deployed by the US States Attorney Generals, which has effectively removed dangerous individuals from access to such services," Mr Sullivan said.

Like most social networking sites, Facebook prohibits sex offenders from using its site, but without access to data on the sex offenders register, has to rely on its investigations and reports from other users to hunt down the predators.

Mr Cameron said he would raise the issue at the next Australian Police Ministers Council in the discussion on cyber crime.

Last month, the Victorian Government made it a requirement for sex offenders to provide police with all details of internet usage.

But after the Sunday Herald Sun revealed details of an intellectually-disabled sex offender using Facebook to look for women, Mr Cameron indicated he was prepared to look at further co-operation with Facebook.

The sex offender, who, after 11 years of detention, was released last month for court-ordered treatment, changed his name after the Sunday Herald Sun's story and is now calling himself "Billy Wang".
