After working for several years on Patterson's staff, Credlin moved to become an adviser to Senator
Richard Alston, the
Minister for Communications in the
Howard government. Her time as chief of staff attracted significant media coverage. She continued in that role until the Liberal Party leadership ballot of 14 September 2015, in which Abbott was defeated and replaced as leader by Malcolm Turnbull. Credlin became a
Sky News Australia contributor in May 2016, with her first appearance on 7 May 2016 during a special weekend edition of
PM Agenda. She began co-hosting a weekly primetime program
Credlin & Keneally from 16 November 2016 until 17 May 2017. Credlin hosts her own show
Credlin each weeknight on
Sky News Australia. As a political commentator and self-described journalist, Credlin has been described as a partisan.
Crikey Paula Matthews wrote in February 2017 that Credlin's support for Tony Abbott and criticism of then Prime Minister Malcolm Turnbull "takes media partisanship to its extreme" and represents "the channelling of a politician directly through a media mouthpiece". Credlin was an ardent critic of the
Victorian government response to the
COVID-19 pandemic, and particularly of then-Victorian premier
Daniel Andrews. Credlin has been lauded by fellow
Sky News hosts for her aggressive questioning of Andrews during his daily press conferences during the pandemic. In 2020, Credlin was criticised for claiming that
South Sudanese Australians were not following government measures intended to stop the spread of
COVID-19 due to problems with language proficiency, Credlin also claimed that South Sudanese migrants were "poorly-assimilated" and had ignored restrictions in an "end-of-Ramadan feast". Credlin's statement was criticised in the media, with
SBS News noting that the vast majority of
South Sudanese people are actually
Christians. Credlin subsequently apologised for her comments. In November 2020, Credlin compared COVID-19 lockdowns to
the inquiry into the conduct of Australian
SAS forces in Afghanistan. During 2020, former Labor Prime Minister
Kevin Rudd started a petition for a Royal Commission into Murdoch owned media. In May 2021 she was accused of inciting violence by suggesting Labor leaders Daniel Andrews and
Anthony Albanese be "whacked" with "baseball bats". In November 2021, she joined anti-vaccine mandate
protests in Melbourne, where members of the crowd carried prop gallows and chanted anti-Andrews slogans. Credlin became a columnist for
The Australian newspaper in July 2021. Her arrival at that paper prompted
Niki Savva to leave the paper and join
The Age and
The Sydney Morning Herald. ==Criticisms and controversies==
