Film and music companies have behaved in a "disgracefully hypocritical" way by lobbying politicians to change copyright laws instead of meeting consumer demands, according to a Labor MP.

Ed Husic, who launched a landmark inquiry into information technology price discrimination when Labor was in government, said he will raise concerns in Labor caucus about the Abbott government's proposal to allow rights holders to apply to block overseas websites hosting material that infringes copyright.

"The market should deal with this but instead they've had lobbyists crawl all over Canberra forcing change by government instead of doing the right thing by consumers," Mr Husic, the member for Chifley in NSW, told Fairfax Media. "It's disgracefully hypocritical that we've got the whole wheel of government turning to address industry interest on this rather than consumers' interests."
