A comprehensive investigation reveals how Australia’s mandatory detention regime inflicts profound harm on vulnerable people, as UN experts arrive to demand accountability.

As United Nations human rights experts touch down in Australia for a landmark 12-day investigation, a damning civil society submission exposes what advocates describe as one of the nation’s most enduring human rights catastrophes. The coalition report, delivered to the UN Working Group on Arbitrary Detention by Australia’s leading refugee and legal organisations, documents a punitive immigration system that detains vulnerable people indefinitely without judicial oversight, subjecting them to harsh conditions that compound trauma and violate international law.​

The timing could not be more critical. With 962 people currently held in immigration detention across the country and an average detention period of 456 days—nearly 30 times longer than Canada’s 16-day average—the UN visit represents the most significant international scrutiny of Australia’s detention policies in years.​

The Human Cost of Indefinite Detention

Behind the statistics lie profound human stories of suffering. The submission details the case of Maksym and Elena, Ukrainian asylum seekers who arrived in Australia in November 2024 seeking protection. Within hours of their arrival, their visitor visas were cancelled and they were transferred to immigration detention, despite officials recognising their likely asylum claims. For months, they endured restricted communication, denied access to their phones and limited internet connectivity, while authorities required them to discuss welfare concerns in front of security officers—replicating the surveillance culture they had fled. They remained detained for four months despite committing no crimes and posing no community risk, their mental health deteriorating until legal intervention secured their release.​

Their experience exemplifies what legal experts characterize as arbitrary detention. “Australia continues to operate a regime of mandatory immigration detention which is often punitive, there is no independent or judicial review of the ongoing necessity for detention in each individual case, and the grounds for securing release from detention are very limited,” the submission states.​

The demographic transformation of Australia’s detention population reveals the system’s punitive shift. While asylum seekers once dominated detention centres, 56% of current detainees are now individuals whose visas were cancelled on character grounds—many pipelined directly from prison to immigration detention upon completing criminal sentences. This “prison to deportation pipeline” particularly impacts New Zealand nationals, who comprise 18.8% of the detention population, alongside significant numbers from Iran (6.8%), India (5.6%), the United Kingdom (5.3%), and Tonga (5.1%).​

The NZYQ Aftermath: From Detention to Digital Prisons

The November 2023 High Court decision in NZYQ v Minister for Immigration marked a seismic legal shift, ruling that indefinite detention of non-citizens with no realistic prospect of removal is unconstitutional. The decision immediately freed approximately 140 people, with at least 224 released by October 2024 and 303 by May 2025. However, the government’s response has sparked fresh controversy.​

Within eight days of the NZYQ ruling, parliament rushed through legislation creating Bridging Visa R (BVR) with 20 mandatory conditions. These included electronic ankle monitoring and 10pm-6am curfews, transforming community release into what the High Court later described as “extra-judicial collective punishment”. In November 2024, the High Court struck down these conditions in YBFZ v Minister for Immigration, finding they violated constitutional protections by infringing liberty and bodily integrity without legitimate purpose.​

Despite this rebuke, the government reintroduced modified monitoring powers. As of September 2025, 356 people held BVRs, with an unknown number subject to electronic monitoring and curfews under revised legal frameworks. The submission warns these measures “extend detention into the community through punitive surveillance,” creating psychological burdens that trigger trauma symptoms in survivors of torture and prolonged detention.​

Awad’s story illustrates this new form of carceral control. After arriving by boat in 1999 and receiving protection, he built a life in Australia, marrying and raising stepchildren while working to overcome torture-induced trauma. Yet he remains trapped in a system where biometric surveillance replaces physical bars, his freedom conditional and his dignity constrained.​

Offshore Shadow: The Nauru Transfer Agreement

Perhaps most controversially, Australia has negotiated a secretive arrangement with Nauru to permanently transfer members of the NZYQ cohort, effectively creating an offshore exile system. Under a Memorandum of Understanding signed in August 2025, approximately 280 individuals may be resettled to Nauru for 30-year visas, with Australia providing up to $70 million annually—potentially exceeding $2.5 billion over the agreement’s lifetime.​

Home Affairs Minister Tony Burke confirmed the first transfers occurred in October 2025, stating: “Cancelling a visa must have significance. And until we established this agreement with Nauru… we faced a scenario where, regardless of the laws they had breached, cancelling a visa had no real effect”. Critics argue this amounts to exporting Australia’s legal and moral responsibilities, creating a two-tiered system where non-citizens face indefinite exile despite having served their sentences.​

UN Visit: A Moment of Reckoning

The UN Working Group’s visit from December 1-12, 2025, represents a critical inflection point. The coalition submission urges the experts to recommend immediate release of all NZYQ cohort members, abolition of mandatory detention, and establishment of judicial review mechanisms with enforceable time limits. It specifically calls for a legally enforceable prohibition on detaining children, noting that while Section 4AA of the Migration Act nominally affirms detention as a “last resort” for minors, this cannot be invoked in court and children continue to be detained under the mandatory framework.​

Madeline Gleeson, Senior Research Fellow at the Kaldor Centre, emphasises the visit’s significance: “After years of growing concern about arbitrary and unlawful detention practices in Australia, this provides an important opportunity for the Working Group to discuss urgent reforms with the Australian government. We call on the government to reaffirm the presumption of liberty, and to ensure that people are only ever deprived of their liberty when it is absolutely necessary to do so”.​

Laura John from the Human Rights Law Centre adds: “Australia is in the midst of an incarceration crisis, with migrants and refugees facing extended periods in immigration detention and the extension of detention into the community through punitive surveillance measures. We welcome this opportunity for the Working Group to hold our government accountable”.​

Systemic Failures and Oversight Gaps

The submission identifies critical oversight deficiencies. Government reporting is “persistently late, inaccurate and incomplete,” excluding people detained at airports, at sea, or in Nauru and Papua New Guinea. The increased securitisation of detention centres, combined with inadequate healthcare and use of force, creates conditions that “contribute to the punitive character and impact of indefinite and arbitrary detention”.​

Specific vulnerable groups face compounded harms. People with disabilities, women, and gender-diverse individuals experience additional challenges in facilities designed without their needs in mind. The lack of post-release support for those who have spent protracted periods in detention creates high risks of re-detention, perpetuating cycles of incarceration and trauma.​

International Obligations and Community Impact

Australia’s mandatory detention regime directly contravenes repeated UN expressions of “serious reservations” about its compatibility with international human rights law. The Working Group has previously issued opinions finding Australia in violation of its obligations, yet the system persists.​

For multicultural communities, particularly those with large migrant populations in Brisbane and the Gold Coast, these policies create ripple effects of fear and family separation. Community leaders report that the threat of visa cancellation and detention hangs over residents who have built lives in Australia, contributing to mental health crises and community fragmentation.

Fr. Brett O’Neill of Jesuit Refugee Service Australia, which has accompanied refugees for over 40 years, frames the visit as a reset opportunity: “We have seen the harsh effects of detention without due process. The Working Group’s visit is an opportunity for Australia to reset; to recognise the profound harm caused by arbitrary detention, and move towards a humane, transparent system that upholds the dignity of every person seeking safety”.​

Path Forward: Recommendations for Reform

The civil society coalition presents concrete reform priorities for the UN Working Group to endorse:

• Immediate release of all individuals in the NZYQ cohort and those facing indefinite detention
• Abolish mandatory detention and introduce independent judicial review with strict time limits
• Prohibit child detention through legally enforceable obligations, not unenforceable principles
• Repeal punitive BVR conditions, particularly electronic monitoring and curfews
• End offshore processing and third-country transfers that circumvent Australia’s responsibilities
• Establish robust oversight with enforcement powers to prevent human rights violations

Paul Power, CEO of the Refugee Council of Australia, delivers a stark assessment: “This civil society report delivers a damning assessment of ongoing human rights violations in Australia’s immigration detention system. It exposes the punitive, highly securitised nature of onshore facilities which, far from functioning as administrative centres, inflict serious harm on people lawfully seeking protection”.​

As the UN experts prepare their preliminary findings for release on December 12, 2025, Australia stands at a crossroads. Will it continue down the path of punitive deterrence, or will international scrutiny finally catalyse transformation toward a system that respects human dignity and complies with international law? For the 962 people currently detained and the hundreds more living under restrictive visa conditions, the answer cannot come soon enough.
