Stan Grant has quit the ABC altogether, months after he went on leave following racial abuse.

His departure was reported on Tuesday, and comes months after he stepped down as the host of Q+A.

Grant had left the show in May after being subjected to 'relentless racial filth' after appearing on a panel discussing colonialism ahead of King Charles' Coronation.

He accused the ABC of 'institutional failure' and claimed no one in management offered him support.

Grant has since told Sky News Political Editor Andrew Clennell he'd resigned as a permanent staffer weeks ago, but stressed there was no 'bad blood' between him and the public broadcaster.

The former ABC host said he was still keen to collaborate with the network in the future but simply had other things he wanted to do.

Last month, the ABC revealed Grant would not be returning to host Q+A, but said he would 'move on to new projects' within the company.

The news comes on the same day it was revealed ABC Chair Ita Buttrose would also be walking away after five years in the role.

Communications Minister Michelle Rowland made the shock announcement on Tuesday.

'Ms Buttrose is a giant of Australia's media industry, and the government thanks her for her exemplary service as chair of the ABC,' Rowland said in paying tribute to the media icon's time as head of the national public broadcaster.

'She has much to do in the remainder of her term and will leave the ABC stronger than when she was entrusted with the role in 2019.

'She navigated the public broadcaster through a challenging period that included strident political criticism, the Covid-19 pandemic and the ongoing transformation of the ABC so it can remain an essential part of Australian life in the digital age.'

Her five-year term will end in March and she will not seek reappointment.

Meanwhile Grant on Saturday unleashed on his former program Q+A, claiming panel members are primarily chosen to spark conflict and viewers are encouraged to form a 'lynch mob' on social media.

'You go on Q+A and the first thing you do is you introduce a panel that have more often than not been picked because they have conflict, rather than seeking to find connection,' Grant told the Canberra Writers Festival on Saturday, according to The Australian.

'Then you say, 'go on social media', basically form your lynch mob, hit the person you hate and pile on.

'I can't do that anymore and I don't think that is what you want from our media. I think we are failing you and we must find a better way to doing it.'

The format of Q+A involves bringing in five panel members who often share differing views to discuss the key issues of the day and take questions from audience members.
