The Albanese government will next week bring legislation to parliament to allow it to re-detain the criminals released, after the court on Tuesday published the reasons behind its decision.
The laws have been described as a "robust preventative detention and community safety order regime", modelled on high-risk terrorist laws enacted under the coalition government.
It comes as another of the released detainees who authorities had not been able to locate was found by security agencies.
It's understood the former detainee is now complying with the stringent visa conditions that have passed following the High Court ruling.
As well, a bill to allow a court to strip Australian citizenship from people found guilty of serious crimes, including terrorism and espionage, was introduced to parliament on Wednesday.
Home Affairs Minister Clare O'Neil said the laws would repeal measures of previous citizenship stripping powers that were deemed invalid by the High Court.
"The bill provides an appropriate mechanism to deal with dual-Australian citizens who have committed crimes that are so serious and so significant that they demonstrate the repudiation of their allegiance to Australia," she said.
"The government understands the complexities of this significant legislation and is committed to a robust and workable regime. Laws that fail in the courts don't make our country any safer."
Citizenship can only be stripped under the measures if an order is made by the Home Affairs minister, but must be before sentencing is carried out.
Australian citizenship would not be able to be stripped if it would make someone stateless.

Ms O'Neil urged the opposition not to stand in the way of laws to protect the public.
"Our government is now going to move quickly to establish the toughest possible preventative detention regime," she told ABC News.
"Peter Dutton is very good at saying 'no' and they've played a lot of politics with this issue.
"Let's see now if they come into the parliament and help us keep the Australian community safe."
Ms O'Neil defended her government's response to the overturning of a 20-year precedent, saying a police operation and case management had been established within eight days of the court decision.
"I have never seen an Australian government move so quickly to adapt to a major constitutional decision," she said.
Constitutional law expert Anne Twomey said the court's judgment would support legislation that allowed an individualised process.
Seeking to categorise the entire cohort as suitable for re-detention because they posed a risk to the community would not succeed, she said.
"This judgment wouldn't support that," Professor Twomey told ABC radio.
"Trying to detain an entire group of people simply because they're unlawful non-citizens is not going to work."
Convicted murderers, rapists and those who have committed sexual offences against children are among the people released.
