The Abbott government is considering a major crackdown on online piracy, including forcing internet service providers to block websites that allow users to illegally stream or download movies, music and television shows.

The federal government is also considering implementing a "graduated response scheme" that could lead to consumers' internet accounts being temporarily suspended if they ignore notifications to stop downloading illegal content.

If implemented, the reforms could see popular file sharing sites such as The Pirate Bay blocked by some internet service providers.

Attorney-General George Brandis flagged the changes in a major speech to the Australian Digital Alliance forum on Friday.
