Labor MP Tim Watts also denied the bill would prevent ABF officers from making disclosures that fell within the Public Interest Disclosures Act.
“All staff and contractors would have the right to report child abuse if they had raised it with their employer and nothing was done about it,” he said.
However, the act allows only for whistleblowing to media or another entity outside government in extremely limited circumstances, such as in the case of “substantial and imminent danger”.
Explaining the need for the gag laws, Dutton has said: “Every day, the department and the Australian border force within it will create, receive and use critical and important information, including intelligence and personal information. Much of this information will be sensitive and complex.
“It is therefore necessary that information secrecy and disclosure arrangements should be in place not only to protect information but also to enable the disclosure of information in appropriately controlled circumstances.”
He said the formation of the ABF meant “we are equipped to deal with future challenges and threats to our national security and financial prosperity and our borders are stronger than ever before”.
The prime minister, Tony Abbott, told a swearing-in ceremony of ABF staff they were more than just officials.
“You are guardians of our safety, our security and our prosperity,” he said. “May God bless you, may God bless your work, may God bless the country you are helping to protect and prosper.”
Labor’s immigration spokesman, Richard Marles, said the new agency would “play a crucial role in ensuring the integrity of Australia’s borders”.
