Mark Latham

After posting a sexually explicit and homophobic tweet targeting MP Alex Greenwich in 2023, Latham faced two separate civil proceedings. The Federal Court found him liable for defamation and awarded Greenwich 140 000 dollars; Latham's appeal was dismissed in June 2026. In separate proceedings, NCAT found unlawful homosexual vilification and sexual harassment in April 2026, ordering, among other remedies, 100 000 dollars in damages and the removal of posts.

Following a verbal altercation with Steve McMahon at Rosehill Gardens in April 2025, during which Latham acknowledges swearing, the Australian Turf Club imposed a twelve-month ban. Racing NSW subsequently opened its own investigation and brought two disciplinary charges. As Latham was a highly active parliamentary critic of the regulator, the Privileges Committee was asked to determine whether the investigation constituted retaliation for his parliamentary activity.

Reports revealed that Latham had taken photographs of several female MPs inside Parliament and accompanied them with sexualised or disparaging comments in private messages. He acknowledged that certain photographs and remarks were ill-judged and apologised to the parliamentarians concerned.

In November 2025, the NSW Legislative Council Privileges Committee found that Latham had disclosed privileged contents of a Law Enforcement Conduct Commission report relating to Operation Askern on four occasions, three of them after being explicitly warned of its status. The committee considered these disclosures a series of contempts of Parliament. In the same report, it also found that he had twice disclosed an individual's private address without justification, constituting an abuse of parliamentary freedom of speech.

Latham introduced a parental rights bill in NSW that would, among other measures, have prohibited or severely restricted teaching about gender fluidity and imposed restrictions on support for transgender pupils. The bill faced strong opposition from organisations, teachers and experts. The NSW government rejected it, and the legislation ultimately lapsed in 2023.
