A Northern Territory police officer has been sacked after allegedly making racist remarks on multiple occasions.

It comes only weeks after the Police Commissioner Michael Murphy apologised to Aboriginal Territorians at the Garma Festival for past injustices inflicted by the police and vowed to eliminate racism from the force.

On Monday, the NT police said a 52-year-old recruit constable has been dismissed following serious breaches of discipline under the Police Administration Act 1978.

"After allegations that he made racist remarks on repeated occasions the officer was served a show cause letter to explain why his probationary appointment should not be terminated," a statement read.

"Following consideration of all information, the recruit was dismissed on Friday, August 16."

Deputy Commissioner Martin Dole said racism would not be tolerated in the force, arguing the decision reflected the NT Police's commitment to maintaining integrity and respect within their ranks.

"Our members are fully empowered to report any such conduct, and swift actions are taken when it is discovered," he said.

"An internal investigation was promptly launched after the allegations were made, leading to the officer's dismissal.

"This action highlights the NT Police's dedication to upholding its values and ensuring a safe and inclusive environment for all."

Territory police have long been shrouded in accusations of institutionalised and systemic racism by Indigenous people in the NT, who have argued they've been subject to over-policing, violence, and death.

This has been widely circulated during the coronial inquest into Warlpiri-Luritja man Kumanjayi Walker, who was shot dead by NT Police Officer Zachary Rolfe in 2019.

Rolfe was acquitted of all charges.

The inquest has heard members of the elite Territory Response Group (TRG) handed out a number of racist 'awards', including for "c**n of the year", whilst other 'awards' issued between 2007 and 2015 were considered "so offensive" by ICAC Commissioner Michael Riches they weren't in the public interest to circulate.

The NT police have appointed former South Australian Police Officer and lawyer, Leanne Liddle, as executive director of the community resilience and engagement command to spearhead change in the organisation.

The Arrernte woman is working on an anti-racism strategy, including having Indigenous language call centre operators and a 30 per cent Indigenous workforce.
