HuffPost and Fairfax Media have announced that their two-year long joint venture has ended.
Employees were notified of the move on Wednesday, with HuffPost saying some redundancies were possible.
"Employees were briefed today on the decision of HuffPost and Fairfax to bring the Australian joint venture to an end," a spokesman for HuffPost Australia said.
"HuffPost will operate a standalone Australian edition from December 1 with a smaller local team.
"If redeployment is not possible, regrettably redundancies will occur."
If these other opportunities are not found, about 20 Sydney-based HuffPo staff members could be left without a job. About 25 are currently in the team.
The JV between the two companies saw the launch an Australian edition of the HuffPo in August 2015. Fairfax held a 49 per cent interest.
The Huffington Post was launched in 2005 by Arianna Huffington, before being sold to AOL in 2011. Ms Huffington left the venture in 2016.
The Australian edition, when launched, was the 15th addition to the global brand of titles.
In a post introducing the new title, Ms Huffington described it as a place to showcase contributors who use videos to share their ideas, coverage of solutions, and, in particular, covering "Australia's work culture".
