China urges probe after detainee suicide in Melbourne

China’s embassy in Australia has asked for an investigation after a Chinese national died by suicide in a Melbourne immigration detention centre on July 10, adding diplomatic pressure to ongoing scrutiny of Australia’s onshore detention arrangements.

The Chinese government said it had lodged “solemn representations” with Australian authorities and raised concerns about the safety and rights of Chinese citizens held in Australia’s immigration detention system, according to the source material.

Internal documents point to prior self-harm risk

Internal documents cited in the source material describe the woman as being in her mid-30s and record a history of self-harm, including recently expressed suicidal ideation.

Those documents indicate Australian Border Force officials notified Secure Journeys less than 24 hours before she was found dead.

Contractor custody and official investigations

The detainee was in the custody of Secure Journeys at the time of the incident, according to the internal documents and statements referenced in the source material.

Secure Journeys is described as an Australian subsidiary of the US-based Management and Training Corporation (MTC).

Victoria Police are investigating the death and are preparing a brief of evidence for the Coroner’s Court of Victoria, the article said. Investigators have not released further details.

The Department of Home Affairs and Secure Journeys declined additional comment, citing privacy obligations and the ongoing investigation.

Detention network incident records and oversight questions

The death comes after operational issues reported within the Secure Journeys network, including incidents described as high-risk escapes and staff injuries, according to the source material.

Parliamentary records cited in the article show 360 incidents of threatened or actual self-harm across Australia’s onshore immigration detention network between July 2025 and March 2026.

The source material said Home Affairs Minister Tony Burke previously summoned MTC leadership in September 2025 to address concerns about staffing models and security protocols.

With police and coroner processes underway, a central uncertainty remains what those investigations conclude about monitoring and risk management in the hours before the woman’s death.
