C/T Group

C/T Group, also known as Crosby Textor, is an Australia-founded professional-services firm operating across political consultancy, lobbying, social research, political polling, corporate intelligence, corporate strategy, and private investigations. It was established by political strategists Lynton Crosby and Mark Textor and became particularly associated with the Liberal Party of Australia and with mainstream conservative or centre-right political parties in several countries. The firm’s work combines opinion research, campaign planning, strategic communications, political advice, and intelligence-oriented services for political and corporate clients. Its international activity has included Australia, the United Kingdom, Canada, Africa, Italy, and New Zealand. Although its political work has received the greatest public attention, the group’s stated service range extends beyond election campaigns to corporate strategy, research, intelligence, and investigations. In Australia, C/T Group has been linked to Liberal Party election operations and strategy during the 2010, 2013, 2016, and 2022 federal elections. It also worked on Campbell Newman’s Liberal National Party campaign in the 2012 Queensland election and on the Country Liberal Party’s successful campaign in the 2012 Northern Territory election. Outside Australia, the firm provided strategic support to Boris Johnson’s successful 2008 campaign for Mayor of London. In 2017, Crosby was reported to have played a leading role in the Conservative Party’s campaign for the United Kingdom general election. The Conservatives remained the largest party but did not win an outright majority, and the campaign was sharply criticised by commentators for its negative tone and performance. The firm has also undertaken public-opinion research on contested social and constitutional issues. In 2014 it published polling indicating majority Australian support for legalising same-sex marriage. In 2020 it conducted research concerning a proposed Indigenous Voice to Parliament and reported majority support for constitutional entrenchment of such a body. In the 2023 Australian referendum on the Indigenous Voice, C/T Group was associated with the unsuccessful Yes campaign, commonly known as Yes23. C/T Group has faced scrutiny over methods attributed to it or related entities. A 2019 Guardian investigation reported that CTF Partners, described as a subsidiary, created apparently independent social-media accounts and used them behind Facebook advertising to advance political positions, including support for a hard Brexit. In 2024, a Financial Times investigation reported allegations that C/T Group had supplied forged or fabricated banking records in several United Kingdom court disputes. The allegations were described in exceptionally serious terms, including claims of industrial-scale forgery and apparent criminality. These reports have made the firm a subject of controversy in addition to its established role as a political and corporate advisory organisation. Public information identifies Crosby and Textor as the firm’s founders and most prominent historical figures. The available reference material does not establish a complete current executive roster, ownership structure, headquarters, founding year, or official website. Accordingly, those fields remain unspecified here.

C/T Group was founded by Australian political strategists Lynton Crosby and Mark Textor under the name Crosby Textor. The firm developed as a political consultancy serving parties and campaigns while also building capabilities in polling, social research, corporate intelligence, corporate strategy, lobbying, and private investigations. Its historical political profile has been closely connected with Australia’s Liberal Party and with conservative or mainstream right-wing parties internationally. The firm’s Australian work has included election strategy and polling for Liberal Party operations during the 2010, 2013, 2016, and 2022 federal elections. It also provided campaign support for Campbell Newman’s Liberal National Party in Queensland in 2012 and for the Country Liberal Party in the Northern Territory election held that year. The Northern Territory campaign was successful. C/T Group’s international political work included Boris Johnson’s successful campaign for Mayor of London in 2008. In the United Kingdom, Lynton Crosby became a prominent Conservative campaign adviser. In 2017, Prime Minister Theresa May announced that Crosby would have a leading role in the Conservatives’ general-election campaign. The Conservatives lost their parliamentary majority, although they remained the largest party. The campaign attracted negative commentary, including criticism that its approach was excessively negative and strategically ineffective. C/T Group has also used polling and research to address public-policy questions. In 2014, polling published by the firm indicated that most Australians supported legalising same-sex marriage. In June 2020, the firm conducted research on the proposed Indigenous Voice to Parliament and reported majority support for constitutional recognition. The firm was later associated with Yes23, the campaign supporting the Voice proposal at the 2023 Australian referendum, which ultimately failed. The organisation and related entities have attracted scrutiny over political-marketing practices. In 2019, The Guardian reported that CTF Partners, described as a C/T Group subsidiary, had created social-media accounts presented as independent and used those accounts in connection with Facebook advertisements. The reported activity promoted political ideas such as a hard Brexit while obscuring the commercial or organisational origin of the messaging. In 2024, the Financial Times reported allegations involving forged or fake banking records in several ongoing United Kingdom court cases. The allegations were characterised as involving industrial-scale forgery and apparent criminality. The available reference material does not establish the final legal disposition of those allegations. They nevertheless represent a major reputational controversy connected with the group. By 2025, Mark Textor continued to be described publicly as a highly influential political strategist. The available material does not provide a confirmed founding year, current management list, ownership details, headquarters, financial information, or official website. C/T Group is therefore best documented as an active, internationally oriented political and corporate advisory firm whose public identity remains strongly associated with Crosby and Textor and with conservative campaign consulting.
