Mick Gatto

Domenic "Mick" Gatto (born 6 August 1955) is an Australian boxer, debt collector, and professional mediator within the Victorian building industry. He was named as a standover man during the Royal Commission into the Building and Construction Industry. Gatto was involved in Melbourne's illegal gambling scene in the 1980s and 1990s. after Veniamin pulled out a .38 handgun and threatened to kill him. Gatto claimed that during a struggle he was able to turn the gun around on Veniamin and fire one shot into his neck, and one shot in the eye. He also claimed that during the argument, Veniamin had implicated himself in the deaths of Dino Dibra, Paul Kallipolitis and Graham Kinniburgh.

At the time of charging Vince Benvenuto with the 2002 murder of Victor Peirce, it was alleged that Gatto had links to both men and to Faruk Orman, the man later convicted of Peirce's murder and acquitted in 2019. No charges were laid against Gatto.

Royal Commission In proceedings before the Cole Royal Commission, it was heard that Gatto was involved in resolving certain business disputes. Witnesses attested that Gatto and his business associate, David "the Rock" Hedgcock, had been involved in solving industrial relations problems in the construction industry. One witness, a representative of Baulderstone Hornibrook expressed the fears of a colleague stating, "...he expressed some concerns about his safety, that people associated with this deal were the sorts of people that break legs..." Gatto and Hedgcock's solicitor rejected any implication they had used threats or intimidation. Appearing before the Royal Commission in 2002, Gatto claimed he was being made a scapegoat by the inquiry and strenuously denied he was a standover man.

Community involvement concerns When concerns were raised in the media regarding Sydney neurosurgeon Dr Charlie Teo in 2019, the Sydney Morning Herald was contacted by an associate of Gatto. The associate, according to the reporter Kate McClymont, expressed concern to the newspaper at the questions they were raising with Teo, including about alleged sexual harassment of colleagues in Arkansas, United States. Teo denied he had raised the matter of the Heralds questions with Gatto. Gatto had hosted a fundraising dinner for Teo's Cure for Life Foundation in 2012. Gatto stated in 2014 that he had raised over $4.5 million for charity over ten years.

Legal and tax problems A former boxing promoter, the government led by Denis Napthine in Victoria withdrew his fight promotional licence. He told the court he kept the loaded sawn-off shotgun in his home because of fears for his life, having been threatened by a criminal cartel. The magistrate accepted his fears were genuinely held. Gatto pleaded guilty to two weapons offences and was fined.

In April 2017 it was reported that Gatto settled a long-running dispute with the Australian Taxation Office (ATO). It was claimed that Gatto and his family owed the ATO $15 million; and both parties agreed to settle the matter for less than $4 million. It was reported that in order to pay the ATO, Gatto sold his home for $4.1 million. Gatto and his family also own a residence at , on the Mornington Peninsula.

In 2020 Gatto launched a defamation lawsuit against the Australian Broadcasting Corporation (ABC). Gatto claimed the article made him out to be a "murderer" and "one of Australia's most violent criminals". In 2021 Justice Andrew Keogh ruled in favour of the ABC, stating "Far from being distorted, the article was entirely accurate and correlated with what occurred in those parts of the Proceedings which were reported."

In June 2026, Gatto was arrested without charge because of "alleged financial offences".

Industrial relations and construction industry payments

In June 2026, an investigation by The Age and 60 Minutes, based on leaked financial records from an associate, reported that Gatto and his business partners had received millions of dollars in payments from more than a dozen subcontractors working on Victoria's "Big Build" infrastructure program. The leaked documents showed ongoing transactions through 2025 and 2026 to Gatto-controlled consulting entities, including Arbitrations and Mediations Pty Ltd and Bridgeview Consulting.

According to the reports, several subcontractors (including Cycon Civil, Project Labour Solutions, M1 Trades & Labour, and Major Cranes) had paid sums ranging from tens of thousands to over $1million to Gatto, who operates as a self-styled mediator and arbitrator. Some company owners publicly stated they felt compelled to employ Gatto for "industrial relations services" to resolve blockages by the CFMEU and secure access to state and federally funded construction projects. Gatto declined to comment on the specific details of the leak, but has previously denied receiving payments from Big Build subcontractors or being involved in any wrongdoing.
