The Australian Government could be facing tens of millions of dollars in compensation claims following a landmark High Court decision that found the Department of Home Affairs liable for the unlawful indefinite detention of a group of immigration detainees.
The case centres on the so-called NZYQ cohort, individuals who were held in immigration detention despite being unable to be deported from Australia.
The ruling represents one of the most significant immigration law decisions in recent years and may open the door to substantial compensation claims against the Commonwealth.
Speaking to reporters, Home Affairs and Immigration Minister Tony Burke said the government was still assessing the implications of the judgment and could not yet estimate the potential cost to taxpayers.
“The courts have not yet made any orders regarding compensation,” Burke said.
The minister noted that at the time the individuals were detained, the government of the day was acting according to what it believed was the law.
“If we’ve been acting in good faith following what we were told was the law, then we shouldn’t be liable in any way. That particular argument, however, has been rejected,” Burke said.
The High Court’s decision could therefore expose the Commonwealth to significant financial liabilities if compensation is ultimately awarded to those affected.
The issue has also become politically sensitive, with questions being raised about how future governments can avoid similar situations.
When asked whether new legislation would be needed, Burke argued that the circumstances that led to the NZYQ case were unlikely to occur again because of Australia’s agreement with Nauru.
“The situation will not occur again, because we now have the agreement with Nauru,” he said.
In October 2025, Burke confirmed that members of the NZYQ cohort had begun being transferred to the Pacific island nation under a 30-year agreement reportedly worth approximately $2.5 billion.
The arrangement has been presented by the government as a long-term solution for dealing with non-citizens who cannot be returned to their countries of origin but are considered unsuitable to remain in Australia.
Despite those measures, the legal consequences of the High Court ruling remain unresolved.
Should compensation claims succeed, taxpayers could ultimately bear the cost of one of the most significant legal fallout events arising from Australia’s immigration detention system.
The case has once again placed the nation’s immigration policies under scrutiny, reigniting debate over the balance between border protection, public safety and the fundamental rights of individuals held in detention.
