In March 2010, shadow treasurer Joe Hockey attacked the filter, saying "What we have in the government's Internet filtering proposals is a scheme that is likely to be unworkable in practice. But more perniciously it is a scheme that will create the infrastructure for government censorship on a broader scale". During the 2010 Federal Election, Liberal communications spokesman Tony Smith announced that "a Coalition government will not introduce a mandatory ISP level filter", with Joe Hockey also announcing an intention to vote against the policy if Labor is re-elected. This followed the 2010 Federal Conference of the National Party passing a motion proposed by the Young Nationals to "oppose any mandatory ISP-level internet censorship".
