A further 74 pirating sites such as Limetorrents, Putlocker, Kinogo, and Megashare could be added to the list of sites blocked by nearly 50 internet providers if movie studios succeed in their latest legal move to stop Australians streaming or downloading movies and television for free.

This follows a ruling late last year that granted studios like Roadshow Films, Disney Studios, Warner Bros and Twentieth Century Fox the right to request internet service providers (ISPs) block access to 61 sites that people were using to download movies and TV shows for free.

This second case has occurred because the studios are trying to stay ahead of the pirating sites, which often change names or web addresses to avoid blocks. If granted, it means Australian courts have blocked access to 135 piracy sites.

The studios have filed an application in the Federal Court of NSW asking Justice John Nicholas to order ISP's "take reasonable steps to block access to the target online locations".
