WA coroner won't release Dhu footage

The West Australian coroner has refused to publicly release footage of a dying Aboriginal woman in custody despite her family supporting the idea.

Ms Dhu, whose first name is not used for cultural reasons, died two days after being locked up at South Hedland Police Station in August 2014 for unpaid fines totalling $3622, stemming from offences including assaulting an officer.

She died during her third visit in as many days to the Hedland Health Campus from staphylococcal septicaemia and pneumonia, following an infection in her fractured ribs that spread to her lungs.

A four-week inquest has been held in Perth in two parts, and on Thursday, the court heard the final lot of evidence.

Ms Dhu's family initially opposed media requests to obtain the security footage from the lock-up, which was repeatedly played in court, but their lawyers said on Thursday the family had reconsidered their position and believed it was in the public interest.

However, Coroner Ros Fogliani dismissed the application.

Lawyers for relevant parties in the inquest, including Ms Dhu's family and the police and medical staff who had contact with her, will now provide written submissions to the coroner.

Ms Fogliani is expected to deliver her findings later this year.
