Releasing footage of the final days of an Aboriginal woman in custody would be the most powerful and effective way of honouring her memory, her father has told the West Australian coroner.
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 charges including assaulting police.
Ms Dhu's family initially opposed media requests to obtain the vision, which was repeatedly played during an inquest, but their lawyers later said the family had reconsidered their position and believed it was in the public interest.
Coroner Ros Fogliani dismissed the application, saying the footage was distressing and Ms Dhu's privacy outweighed the public interest, but she is now reconsidering the matter and heard submissions on Wednesday to a packed court room.
Some footage shows police dragging and carrying Ms Dhu's limp body to a police van.
Another clip shows an officer pulling Ms Dhu by the wrist to sit her up before dropping her, causing Ms Dhu to hit her head.
"I want some truth and justice for my granddaughter," Carol Roe told reporters outside court.
She and her supporters also chanted: "Black lives matter."
Ruth Barson from the Human Rights Law Centre said the grandmother and mother, Della Roe, wanted Australia to see how Ms Dhu was treated.
"Carol and Della want Australia to bear witness to the mistreatment and the injustice that Ms Dhu endured," she said.
Counsel for Ms Dhu's father Robert Dhu told the coroner he now only objected to the release of the last portion of footage of his daughter's final moments.
Lawyer Tony McCarthy, representing some media outlets, argued for the entire footage to be released and submitted that the coroner had no discretion.
He said the only way to adhere to an open system of justice was to release the vision, adding neither the coroner nor the media could adequately describe in words what the footage showed.
Counsel assisting the coroner Phillip Urquhart said it was important to preserve Ms Dhu's dignity and Ms Fogliani would have to consider whether Ms Dhu would have wanted the footage publicly released.
Ms Fogliani is also considering whether the footage should be released at the same time as her findings into Ms Dhu's death and if parts of the vision should be pixelated.
Police Commissioner Karl O'Callaghan has previously said Ms Fogliani gave good reasons for her original decision but added he did not oppose the release of the footage.
During the inquest, some officers testified they thought Ms Dhu was faking illness and was coming down from drugs, while some medical staff also thought she was exaggerating.
Ms Dhu 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.
Ms Fogliani has reserved her decision regarding the footage.
