Crossbench MPs and senators are putting pressure on the Morrison government to provide better protections for journalists and whistleblowers as a new report highlights an erosion in press freedom.
Former Greens senator Scott Ludlum, who co-authored the report - backed by GetUp and the Digital Rights Watch - said he was "horrified" by the police raids on the ABC headquarters and journalists homes a few months ago.
He said the report shows the heat has been turned on the media over the past 10 to 15 years.
"Nobody should be arrested or have their homes gone through or possessions or devices gone through simply trying to their job," Mr Ludlum told reporters in Canberra on Wednesday.
He said journalists needed protections, as do their sources.
Independent MP Andrew Wilkie said the federal government now has "excessive powers" since the 9/11 attacks in 2001 - which has seen has 75 separate pieces of security legislation passed - many of which he believes are "entirely unnecessary".
He said it was not good enough for the government to flick concerns of media freedom to the parliamentary intelligence and security committee because it had signed off on every one of those 75 pieces of legislation in the past 18 years.
Greens senator Sarah Hanson-Young said the Senate was undertaking its own inquiry into the issue and expects legislation will come out of that in the new year.
Mr Wilkie said there are already two bills in the House of Representatives put forward by himself and Centre Alliance on protections and a bill of rights.
However, the government controls the numbers in the house and decides what business is dealt with.
"We now look to the government and to the opposition to get behind these issues and to allow that business to be brought on," Mr Wilkie told reporters.
