"We need urgent action from government to protect the right to know," Murphy added.
In a rare instance of unity, media executives from the country's biggest news organisations have called for reforms to protect press freedom after two police raids last month — one on the home of a News Corp. journalist and another at the headquarters of the Australian Broadcasting Corp.
The journalist whose travel records were obtained, Daniel Oakes, was part of an ABC team that published "The Afghan Files," a 2017 article based on leaked military documents that described potential war crimes by Australian armed forces in Afghanistan.
Last year, the government passed sweeping legislation that included harsher penalties for leaking classified or secret information. The law made it illegal for government officials to disclose such information and in some cases, for journalists to receive it. The alleged whistleblower behind the "Afghan Files" documents, a former military lawyer, has already identified himself and is facing charges.
A spokeswoman for the federal police declined to comment Monday on the seizure of the travel records, saying the investigation is continuing.
A Qantas spokeswoman said in a statement Monday that the airline receives numerous requests for information from law enforcement agencies. She said the airline is not informed about the occupation of passengers in such requests and provides information only on passengers who are subject to a criminal investigation.
Christian Porter, Australia's attorney general, has said that he is "seriously disinclined" to prosecute journalists except in the most exceptional of circumstances.
Still, there is a "worrying chasm" between the government's actions and its words, said Joseph Fernandez, an associate professor of journalism at Curtin University in Perth.
On an international stage, such police activity is at odds with Australia's reputation for having a transparent democracy and could "embolden other oppressive governments," Fernandez said.
"We are seriously undermining our credibility when it comes to upholding basic rights and freedoms," he added.
