Labor will seek to force the government to change controversial encryption-piercing legislation, introducing amendments recommended by a bipartisan parliamentary committee and addressing concerns from United States lawmakers which threaten a landmark security deal.

The government rushed the Assistance and Access Bill through Parliament late last year with Labor's support. The opposition has since accused the government of breaking a promise to put in place a series of amendments to the legislation.

The laws, which compel a company to provide assistance or introduce technical changes to its platforms to access user data, have been heavily criticised by the tech sector. The companies argue the legislation undermines the security of their products and erodes user trust.

A landmark law enforcement data access agreement between the US and Australia is also at risk, with US Congress judiciary committee chair Jerrold Nadler having warned the encryption legislation might disqualify Australia from an agreement under the US Clarifying Lawful Overseas Use of Data (CLOUD) Act.
