The measures stemmed from a High Court decision that ruled indefinite detention was illegal and resulted in 215 immigration detainees being released as of October 18, 2024.
Of those, 143 have electronic monitoring bracelets and 126 are subject to a curfew after the federal government passed emergency legislation to add extra restrictions to the cohort.
The legislation overreached the separation of powers between the courts, that administer criminal punishment, and the commonwealth government, the High Court found.
Breaking bridging visa conditions, including electronic monitoring restrictions or a curfew, would result in a mandatory minimum one-year prison sentence.
"The imposition of each of the curfew condition and the monitoring condition on a (bridging visa R) is prima facie punitive and cannot be justified," the High Court's decision on Wednesday said.
The High Court bid was launched by a stateless Eritrean released from immigration detention under the previous court ruling in November 2023 and was charged with six offences for failing to comply with curfew and monitoring.
The federal government had planned for all possible outcomes of the High Court case, including the possibility of further legislation, Home Affairs Department legal counsel Clare Sharp said.
Neither curfew nor electronic monitoring applied to 64 people - 56 of whom previously had at least one of the restrictions, which has cost the taxpayer more than $73 million.
But the removal of restrictions includes 28 people being taken into police custody.
Of the 215, there are 12 people convicted of murder or attempted murder, 66 for sexual offences, 97 for assault, 15 for serious drug offences, 15 for domestic violence, five for people smuggling and five had low-level or no offences.
Since their release, 62 people have been re-detained at some point.
State and territory police have charged 65 people since their release - 20 of whom are in remand. The rest were in the community either on bail or because their case had been finalised.
