Allison Langdon is one of Australia's most respected journalists.

In 2023, Langdon took over hosting duties on A Current Affair, Australia's No. 1 daily current affairs program.

Prior to that, Langdon was co-host of TODAY, alongside Karl Stefanovic. She joined TODAY on January 4, 2020 in what became the biggest news year in modern memory, starting with bushfires that rolled into COVID-19, economies in freefall, Black Lives Matter protests, the Beirut explosion, the US election and then ending the year with American politics in turmoil. 

Langdon previously co-hosted Weekend TODAY with David Campbell in 2019, combining her presenting commitments with her 60 Minutes role as a reporter. 

She joined 60 Minutes in 2011. Among her achievements include stories she has filed from Somalia in the midst of a brutal civil war, venturing into the raging heart of one of the most active and dangerous volcanoes on earth and coming face to face with Grizzly bears in the Canadian wilderness.

Langdon joined 60 Minutes after nine years in the Sydney newsroom, where she frequently travelled the globe to cover major stories. She has also presented the 6pm Nine News Sydney bulletin and filled in on TODAY, co-anchoring the network's coverage of the Queensland flood disaster and reporting for the telethon that raised more than $10 million for the victims. 

In 2010, while in South Africa for the FIFA World Cup, Langdon was the only Australian journalist to make it into Cameroon to cover the plane crash that killed six Australian mining executives. At home, she played a key role in Nine's award-winning coverage of the Australian federal election and hosted the prime-time documentary 'A Royal Engagement' when Prince William and Kate Middleton announced their plans to marry. Other major news events Langdon has covered include the drug wars in the Mexican town of Juarez, the bombing of the Australian embassy in Jakarta, and the return to Balibo in East Timor with the families of the five Australian newsmen killed during the Indonesian invasion in 1975.

She wrote the book 'The Child Who Never Was –The Tegan Lane Story' (released in 2007) after covering the inquest into the disappearance of the baby born to former water polo champion, Keli Lane. In December 2010, Lane was convicted of the baby's murder.

She has also co-hosted Vision Australia's Carols by Candlelight with David Campbell, in 2019 and 2021 (the Sydney-based pair could not attend the 2020 event).  

She lives in Sydney with her husband Michael and their young boy Mack and daughter Scout. She is also an Ambassador for R U Ok?, the Mirabel Foundation and Gidget Foundation.
