The Victorian Aboriginal Legal Service has renewed calls for systemic change to the state's police and justice system after revelations regarding training material and timelines at the Yoorrook Justice Commission this week.

The Commission heard that Victorian Police's cultural awareness training will not be rolled out completely until the end of 2024, involves 3.5 hours of education, and had been completed by only 12 per cent of officers as of March this year.

VALS chief executive Nerita Waight told National Indigenous Times Victoria Police "can only earn the trust of Aboriginal communities with transformational, systemic change".

"A few hours of cultural awareness training will not even scratch the surface if it is not part of a longer process of learning and understanding. The evidence given at Yoorrook suggests that Victoria Police have a long way to go and we certainly have not seen a significant change in the way police treat our people," she said.

"Aboriginal Community Controlled Organisations such as VALS are best placed to deliver cultural awareness training – we have over 50 years' experience in providing legal assistance for our people. The Victorian Government should fund ACCOs like us to develop and deliver training to improve cultural awareness across the legal system and government."

"Systemic racism within Victoria Police cannot be addressed without mandatory cultural awareness training for all staff. I cannot stress enough that this training needs to be ongoing and regular, it is a life-long journey, not a half-day meeting."

Police Chief Commissioner Shane Patton faced the Yoorrook Justice Commission this week and formally apologised for racist actions and attempted cover-ups by officers.
