Hacking activist group Anonymous admitted on Tuesday that it was responsible for the attacks that took down at least 10 websites being maintained by the Queensland state government over the weekend.

In its report, News.Com.Au said the online security breach was in response to what Anonymous Australia, presumably the local arm of the international alliance of computer hackers, described as attempts by the federal government "to strip away its citizens' internet rights."

Australians, the hacking group said in a statement, were being forced to "surrender passwords and internet usage data," under the guise of the Parliamentary Joint Committee on Intelligence and Security (PJCIS).

Prime Minister Julia Gillard has expressed support for beefing up online security by allowing government intelligence agencies to monitor activities in social media sites like Twitter and Facebook.

Such would only be possible by compromising the personal data of users, according to Anonymous.

The attacks are still underway, the group claimed, and will be sustained "unless the Government starts acting in the best interest of its people, it will continue to bring the noise."

"We plan to continue targeting 'Gov.Au' websites until PJCIS is rejected," the hacking group warned.

Websites by run by the Queensland government were attacked as Anonymous claimed that state authorities have commenced its monitoring operations that specifically focused on small to medium businesses, education departments and students.

The group insisted that it has evidences against Queensland authorities but offered no details on its claims, according to News.Com.Au.

Anonymous also cautioned the public that though measures that federal authorities have been aiming to impose "our own rights to privacy dwindle ... (while) corporate rights to commercial confidentiality and intellectual property skyrocket."

"We no longer know about many of the activities of our governments while our governments have the means to accumulate unprecedented vast banks of data about us," Anonymous Australia declared.

In an earlier statement, however, Attorney-General Nicola Roxon has assured that the online security amendments will be rolled out with the Australian public having a clear say in the finalisation of laws governing the proposed changes.

"(That) is why I'm asking the Committee to conduct public hearings," Ms Roxon stressed.

She added that for stronger national security, access internet and phone records must be added to the basic functions of Australia's intelligence agencies.

It is also understood that Anonymous launched the attacks to taunt Canberra for its perceived persecution of WikiLeaks founder Julian Assange and another whistleblower in Sydney.
