Opposition leader Bill Shorten says he remains concerned about encryption legislation despite helping pass the controversial laws before the Christmas break.
The laws cleared the Senate on Thursday, after Labor agreed to pass them at the last minute.
The government said the laws were necessary to protect Australians over the holidays and agreed to look at Labor amendments next year.
Mr Shorten concedes the bill was rushed, but is confident the amendments will go through when parliament resumes in February.
"There are legitimate concerns about the encryption legislation," the opposition leader told reporters on Friday.
"But I wasn't prepared to walk away from my job and leave matters in a stand-off and expose Australians to increased risk in terms of national security."
Attorney-General Christian Porter believes Australia is a safer place because of the laws that will now force tech companies to help authorities snoop on encrypted messages.
"This ensures that our national security and law enforcement agencies have the modern tools they need, with appropriate authority and oversight, to access the encrypted conversations of those who seek to do us harm," he said.
Labor agreed to drop its amendments due to national security concerns around terror threats over the holidays.
But its support was contingent on the government amending the new laws in February.
Government senate leader Mathias Cormann said the coalition supports in principle all of the amendments
"The focus yesterday was to secure the very important encryption laws, unamended, through the senate, and it was mission accomplished," he told Sky News on Friday.
The Law Council of Australia says serious concerns remain about the laws, which it believes have been rushed and politicised.
"We now have a situation where unprecedented powers to access encrypted communications are now law, even though parliament knows serious problems exist," president Morry Bailes said.
The Joint Committee on Intelligence and Security made 17 recommendations, covering components of the bill that had been agreed on by the coalition and Labor.
Mr Bailes said the committee should also be involved in helping get the laws right next year.
The laws require tech companies to help police and intelligence agencies see encrypted messages, which experts say will mean encryption will be broken.
Human Rights Commissioner Edward Santow has called for independent oversight and better safeguards.
"This new law will dramatically increase the access of intelligence and law enforcement agencies to the private communications of ordinary Australians, with implications for our right to privacy and freedom of expression," he said.
"The commission, and the public, have not been given a sufficient opportunity to review and comment on yesterday's amendments prior to them becoming law."
