The ABC has apologised to staff who have experienced racism or bigotry in its newsrooms, responding to reports of some staff feeling excluded and unwelcome.
A number of Indigenous and culturally and linguistically diverse ABC News staff detailed their experiences of racism and cultural insensitivity to an internal staff advisory group.
The staff described feeling unwelcome in their workplace, and that their ideas and contributions were not being heard in team discussions.
Some also criticised the internal complaints process, and a lack of support mechanisms for those dealing with racism at work.
The ABC's Director of News, Analysis and Investigations, Justin Stevens, apologised to staff in an email.
"I am sorry."
Mr Stevens said the ABC had been working for years to both improve the diversity of its staff, and change the culture across its newsrooms.
He pointed to increasing numbers of Indigenous staff members and journalists and content-makers from diverse backgrounds, but acknowledged there was more to be done.
"These things should never happen," he said.
"The ABC will not allow or tolerate any racism in the workplace. Ever.
"Our newsrooms, teams and workplace must be respectful, inclusive and welcoming at all times of all employees.
"No-one should ever feel that they don't belong at the ABC because of their cultural background."
The staff-led group also detailed accounts of online abuse directed at Indigenous and diverse staff, coming from members of the public via social media and email.
Mr Stevens thanked the broadcaster's Indigenous and diverse staff, saying increasing the diversity of newsrooms is essential, and improves the journalism they produce.
"ABC News does not employ people as a box ticking exercise."
Mr Stevens said some immediate action would be taken to address the concerns, including better directing new staff towards support networks, training managers in how to deal with abuse online, and working with teams to ensure all staff are heard when pitching stories.
And he called on all staff to work towards change — arguing it should not be left to those subject to "toxic behaviour" to lead the way.
