Former CFMEU leader John Setka has appeared before the Melbourne Magistrates' Court over allegations that he sent threatening, offensive and abusive messages to administrators overseeing the construction union. The case is the latest development in the ongoing scrutiny surrounding the CFMEU following its placement into administration in 2024.

The 61-year-old faces multiple charges, including allegations of using a carriage service to menace, harass or offend, as well as an additional charge relating to allegedly committing an indictable offence while on bail. Prosecutors allege the communications were directed at administrators appointed to oversee the union following federal intervention.

Court documents released on Wednesday detail a series of messages allegedly sent during late 2025. According to the charge sheets, the communications contained abusive language and personal insults directed at administrators, including former union administrator Mark Irving KC. Authorities allege several emails and text messages were sent over multiple days.

During the hearing, lawyers representing Setka told the court that their client had himself been the subject of death threats, which are currently being investigated by Victoria Police. The defence requested that certain personal information, including his residential address, remain protected in court documents due to safety concerns.

Setka has indicated he intends to contest the allegations. His legal team is seeking access to additional documents they argue may be relevant to the case. Prosecutors have opposed some requests, arguing that certain materials are either not held by police or are not directly relevant to the charges before the court. The dispute over evidence is expected to be addressed during a future hearing.

The CFMEU has remained under intense public and political scrutiny since allegations of corruption and criminal influence emerged within parts of the union. In July 2024, the construction division was placed under administration after a series of investigations and media reports prompted government action. Setka resigned from his leadership position during that period.

Prior to his resignation, Setka was one of Australia's most prominent and controversial union figures, having led the Victorian-Tasmanian branch of the construction union for more than a decade. His tenure was frequently marked by industrial disputes, legal challenges, and political controversy.

The court adjourned the matter, with Setka remaining on bail. He is expected to return to court in September as legal arguments continue regarding disclosure of evidence and the progression of the case. No findings of guilt have been made, and the allegations remain before the court. Under Australian law, Setka is entitled to the presumption of innocence unless and until the charges are proven.
