An Indigenous academic has quit the Queensland police service’s Indigenous advisory panel, saying the leadership is unwilling to confront problems in its ranks.

Yuin woman and Associate Professor Marlene Longbottom said she had “no interest” in working with police again after resigning last month as a member of the QPS First Nations advisory group.

“I have no interest in working with the QPS ever again. It’s a waste of my time.”

It comes as the Guardian revealed this week that Brisbane city police watch house officers who were recorded making racist and derogatory comments about Aboriginal people received no sanction and continue to work at the organisation.

Professor Longbottom is the second member of the group to resign this year after academic Gracelyn Smallwood also left the group, saying she no longer believed her work there would lead to ‘necessary changes.’
