Extra police officers have been sent to the remote Central Australian community of Ali Curung to help keep an ongoing conflict between two clan groups under control.

Ali Curung is about 150 kilometres south of Tennant Creek and is home to about 500 people. It has two full-time police officers and at least one Aboriginal Community Police Officer.

NT Police spokesman Damien McCartney says that fighting has continued "on and off" for several days.

About a dozen officers from Darwin and Tennant Creek, and the nearby communities of Ti Tree and Arlparra, have been sent to Ali Curung to keep an eye on the situation.

"These are supporting roles – they're not on duty all at the same time," Mr McCartney said.

"The fights have been more talk and threats, and a few small grass fires have been lit around the community."

Police Duty Superintendent James O'Brien says two police cars were damaged overnight.

Despite that, police maintain the situation is under control and are keen to defuse any perception there is a riot.

On Tuesday, a man was airlifted out of the community with a seriously dislocated elbow, but Mr McCartney said it was not known whether his injury was related to the fighting.

Violent flare-ups in remote communities

There are outbreaks of violence from time to time in remote NT communities, often due to long-running clan disputes or family grievances.

In 2015, about 60 people in two groups on Groote Eyelandt were involved in a family brawl that turned deadly, and two men aged 19 and 29 were killed, one of whom had speared the other.

Wadeye, in the south-west Top End, has also long been a focal point for such flare-ups, including a 2014 mass street fight that involved about 200 people armed with axes and other weapons.

The largest Indigenous town in the Territory, Wadeye has been the scene of clashes between two rival gangs, Judas Priest and Evil Warriors, which erupted in 2006 and lasted for several years.

A 2006 riot involved more than 200 people fighting with rocks, spears and boomerangs, and left about 300 people homeless, with many houses in the community were uninhabitable.

In 2012, police arrested 15 people over a violent disturbance which took place at the community store involving around 200 people.

And in 2013, police made 29 arrests in a crackdown on anti-social behaviour, property offences and unrest within the community, with two people charged with aggravated assault, 16 detained for bail breaches and 37 outstanding warrants executed.
