SYDNEY, July 7 (Xinhua) -- Australian Prime Minister Julia Gillard on Wednesday backed the policy aim of the government's proposed internet filter.
The Australian government plans to introduce a mandatory filter to block sites that contain illegal material.
Gillard said images of child abuse or child pornography should not be accessible on the internet.
However, she has acknowledged the concerns raised by critics of the plan.
"I understand that there's a set of concerns, technical concerns about internet speed, and also concerns that this somehow moves into taking away legitimate use of the internet," she said.
"It's not my intention that we in any way jeopardise legitimate use of the internet," she added.
Greens Senator Scott Ludlam believes more than 500 websites will take part in what is being dubbed 'The Great Australian Internet Blackout'.
The federal government's proposed internet filter would force all internet service providers to block "Refused Classification" material.
