The ABC is under enormous pressure to reveal the full extent of its knowledge of a climate protest outside the family home of Woodside Energy CEO Meg O'Neill on Tuesday morning.

WA Premier Roger Cook issued a please explain to the national broadcaster on Wednesday and on Friday released a damning letter he sent to ABC chair Ita Buttrose.

Woodside has also asked the ABC to explain how the activist group Disrupt Burrup Hub told its social media followers a July 25 climate meeting was to be "filmed by ABC's Four Corners for a report on climate activism in Australia".

Mr Cook told Ms Buttrose it was "doubtful" the three activists, who have since been charged, would have targeted the Woodside boss's City Beach residence without the presence of the ABC TV crew.

"These actions are completely unacceptable and should be condemned by everyone, including the ABC," Mr Cook wrote.

"I have been in public life long enough to understand the vital role the news media plays in a healthy democracy and the right of journalists to report the news with fear or favour.

"However, the fact that an ABC TV crew attended the private home of a WA citizen to document the committing of alleged criminal acts is cause for great concern and morally wrong.

"It is difficult to comprehend how a TV crew could not understand how their presence at a private residence only encouraged these activists.

"It is doubtful 'Disrupt Burrup Hub' would have targeted a private residence if your TV crew was not present to publicise such appalling actions.

"Wittingly or unwittingly, the ABC was complicit.

"As we have seen during the COVID-19 pandemic, single issue activists are now engaging in a new tactic - targeting public figures and their families in their homes.

"Unfortunately this occurred too many times when the former WA Premier and his family were targeted at their own private home. This is completely unacceptable.

"Like many West Australians, I believe we need to unite against this type of behaviour and call it out.

"I hope the ABC will agree and send a clear message to your employees and the WA community."

A Perth Magistrates Court on Wednesday heard the group had allegedly intended to throw paint on Ms O'Neill's house and lock themselves to its exterior to stop her leaving or entering.

The trio was arrested before their alleged scheme was activated but senior ABC bosses have refused to condemn the activists, with the broadcaster planning to use the footage for an upcoming Four Corners documentary on climate activism.

Woodside executive vice-president Mark Abbotsford on Friday said a line had been crossed and Ms O'Neill was still disturbed by the incident.

"There is a line and I think that line has been crossed," Mr Abbotsford told a Senate inquiry.

"She deserves better, as we all do, to be in our homes and to feel safe in our own home, so it's a very disappointing escalation."

Ms O'Neill told a Perth business breakfast function on Friday morning the Disrupt Burrup Hub group were not interested in protesting the oil and gas company's environmental record, and described the alleged actions of the three activists as distressful and threatening.

"Everyone has a right to feel safe in their own home," she told the audience.
