Nicola Gobbo

In 2020, whilst the Royal Commission was still in progress, Victoria Police offered to arrange and pay for her to move to a country without an extradition treaty with Australia so that she would not be able to be investigated or prosecuted for her actions in the Lawyer X matter.

Gobbo's involvement in the Melbourne gangland killings has been dramatised in the Nine Network Australian television series Informer 3838, produced by Screentime, which premiered on 20 April 2020.

Journalist Adam Shand also hosted a six-part Australian crime podcast series in February-March 2020 about Gobbo called Understate: Lawyer X.

In February 2019 a 2016 affidavit written by Inspector Brooke Hall stated that Mick Gatto and Horty Mokbel and others had threatened to kill Gobbo if it was proven that she had been providing information to Victoria Police. At the same time it was also revealed that a threat was made against her oldest child.

It was reported in 2019 that Gobbo had declined to enter witness protection as "she feared police more than her former clients" and was using the name Nikki Gobbo.

In May 2019, it was reported that some of Gobbo's clients who received criminal convictions could be potentially overturned on appeal, on the basis that Gobbo may have provided information to police that led to the conviction of her clients, whilst at the same time representing her clients as their defence lawyer. At the time of lifting the suppression order to reveal Gobbo's identity, the High Court found that [Gobbo] covertly informing on [her] clients was a "fundamental and appalling breach" of the barrister's obligations. In handing down their decision on appeal from the Supreme Court of Victoria, Appeals Court, the judges commented:

Gobbo's partner is Richard Barkho; the couple have two children. As of March 2019, Barkho was serving a five-year custodial sentence for drug trafficking.

Between September 2005 and January 2009 Gobbo was responsible for more than 5,000 reports and regularly spoke to Purana Taskforce detectives whilst working as a defence lawyer for many of Melbourne's organised crime figures. She passed to Victoria Police information about her clients whilst representing them, leading to the prospect of many convictions being overturned. During media coverage of the scandal in 2018 and 2019, Gobbo's identity was subject to a suppression order, and she was referred to as EF, Lawyer X or Informer 3838. The suppression order was lifted in December 2018 when it was reported that she had represented convicted criminals, Carl Williams and Tony Mokbel. On 3 December 2018, the Premier of Victoria Daniel Andrews ordered the Royal Commission into the Management of Police Informants. As part of its inquiry, the Royal Commission examined the number of, and extent to which, criminal cases may have been affected by the conduct of Gobbo. The Commission was due to report to the Government in July 2019; however, as the inquiry proceeded it became clear that this timeline was not achievable. In May 2019 the Commission received $20 million in additional funding and a twelve-month extension to July 2020. The commission delivered the final report and recommendations to the Governor on 30 November 2020.

At the Royal Commission it was revealed that the drug operation was uncovered due to information provided by Gobbo which she had gotten from her client Rob Karam. Gobbo also provided police with phone numbers which were used to gain additional information on the group. It was also noted that police had concluded that the convictions were tainted in 2011 but even though Chief Commissioner Graham Ashton testified that prosecutors would normally be told, that information was not given to Commonwealth prosecutors.

Gobbo, under the pseudonym Witness F, was a witness against Paul Dale, a former policeman accused of corruption. She asserted that Australian authorities have not fulfilled assurances made to her about protecting her safety. The Australian Broadcasting Corporation repeated that Gobbo asserted she had received death threats due to her planned testimony. On 16 April 2008, Gobbo's parked car was engulfed in flames. After the death of Carl Williams on 9 April 2010 and Gobbo refused to testify, the case was withdrawn. Shortly afterwards Gobbo revealed in an interview with the ABC that she was Witness F in the Paul Dale case.

On 8 August 2008, Australian Federal Police announced the arrest of 17 people New South Wales, South Australia, Tasmania and Victoria and the seizure of in relation to an attempt to import 4.4 tonnes of ecstasy in what was described by Australian Customs as the world's largest ever ecstasy seizure. The 15-16 million pills were discovered by Customs in Melbourne packed in over 3,000 tomato tins inside a container from Italy on 28 June 2007. This was followed in 2008 by the 24 June 2008 seizure of 150kg of a white powder that testing indicated was cocaine. By December 2008 the number of people who had been arrested in relation to the attempted importations had reached 26.

Whilst originally understood to be a registered police informant from 2005 to 2009 it was later revealed that Gobbo was recruited as a registered police informant in 1995, 1999 and again in 2005 and was still providing information in 2010 at which time police were instructed that they could no longer accept information from her. Despite this Gobbo continued to offer police information until 2012.

When the TV show Desperate Housewives first premiered in Australia in 2004, Gobbo was one of the Australian women from whom The Age sought a reaction.

Gobbo first came to public attention during the 1996 Australian federal election. In the last week of the campaign, Labor Treasurer Ralph Willis used letters purportedly from Jeff Kennett criticising Liberal leader John Howard. The letters were quickly exposed as forgeries. Gobbo, then a Young Labor member, publicly claimed that the forger was then-Liberal staffer and later Senate president Scott Ryan, who had intended for the forgery to pass initial inspection then rebound on Labor. Despite Gobbo’s signed statutory declaration, Ryan denied the claim.

In 1993, while she was a law student, police raided a house owned by Gobbo and found amphetamines, marijuana, and weapons. Gobbo, her boyfriend, the drug dealer Brian Wilson, and another man were charged with drug possession and pleaded guilty. Gobbo was given a good behaviour bond. Two years later, another raid turned up more amphetamines. Gobbo was concerned that another drug conviction would destroy her law career. No charges were laid, and soon afterwards, she was registered as police informer G395 although she claimed to be unaware of the fact until finding it out through the media.

Nicola Maree Gobbo, sometimes known as Nikki Gobbo, (born 16 November 1972) is an Australian former criminal defence barrister and police informant.
