On August 4 the family of Ms Dhu and their supporters marked the second anniversary of her death in police custody in South Headland with a rally outside Perth's Central Law Courts.
Ms Dhu's family is calling for an independent investigation into her death, as well as demanding the release of CCTV footage that shows her last hours alive in custody.
Ms Dhu, who was 22 years old at the time, had been detained for the non-payment of fines amounting to $3622, but died within two days of being taken into custody.
