Labor strikes deal with government for metadata amendments

The Abbott government has struck a deal with Labor to create a public interest advocate to assess warrants for the metadata of journalists.

Communications Minister Malcolm Turnbull confirmed the addition would come in amendments to controversial metadata legislation now before the lower house.

The advocate will be able to make submissions in response to applications for warrants on matters of public interest.

It's understood the advocate will be a senior barrister and appointed by the prime minister.

The government has also agreed to a presumption against issuing a warrant, meaning police or intelligence agencies must meet a higher threshold to get the warrant.

The agency seeking the warrant will also have to demonstrate they have tried other means to get the information.

Opposition Leader Bill Shorten said freedom of the press was one of the most fundamental parts of democracy and Labor would fight to protect it.

"These changes will mean much stronger protections in place to protect journalists and their sources," he said.
