A young Aboriginal activist has been charged after allegedly assaulting four police officers and spitting on one.

Leilani Clarke, 21, was walking the streets of Redfern in Sydney's inner city in June last year, when she allegedly started punching a 22-year-old woman.

Police jumped in to separate the women when Clarke allegedly lashed out at the four officers.

Clarke appeared in Downing Local Court on Friday on four charges of assaulting two female and two male police officers, one charge of affray using unlawful violence against a 22-year-old woman, news.com.au reported.

The passionate activist who regularly campaigns against 'white colonial oppression' was charged with assault occasioning actual bodily harm and affray against a male alleged victim in Sydney in a separate incident in February.

Police will allege Clarke had 'an unknown number of alcoholic beverages' as she walked down Redfern St with ten friends about 12.20am on June 27.

Soon after, she came across the 22-year-old woman and 'punched her several times in the head', according to police facts.

As Clarke allegedly continued to throw punches, her alleged victim was 'bent over at the waist with the accused holding her hair, punching her … in an unprovoked attack. No words were exchanged'.

A police officer who saw the alleged attack stopped to pull the girls apart as Clarke mumbled, 'I don't know what happened. I just want to go...yes, I am drunk in a public place'.

The officer then found that Clarke was in breach of her bail from the earlier unrelated charge.

Clarke then allegedly sat against a wall and refused police orders to get up as a female constable attempted to handcuff her.

It was then Clarke allegedly tried to throw a punch but missed the officer who was trying to handcuff her.

Clarke was released on bail on the basis that she not drink alcohol and to attend the Kirkton Road Centre clinic

The accused was also allegedly 'making a snorting noise then proceeded to spit saliva' at the female officer, which 'landed on her pants'.

Clarke tried to hold her ground as police dragged her to the caged paddy wagon and allegedly kicked a different female officer twice, according to police facts.

Once at Redfern Police Station, Clarke was being escorted to a custody dock when she lashed out saying 'don't f***ing touch me', police facts state.

As she fought them off, she once again allegedly kicked the second female officer 'in the groin' causing a lot of pain, and a male constable in the stomach.

Another male officer then took Clarke to the custody dock as she continued to resist and allegedly slapped him 'on the face'.

All alleged attacks were recorded on CCTV in the police station.

She was finally placed in time out due to her high levels of intoxication and was released on bail on the basis that she not drink alcohol and to attend the Kirkton Road Centre clinic.

Clarke claims to suffer from self-diagnosed 'transgenerational trauma' passed down through the indigenous part of her DNA.

She is a member of the Butchulla indigenous community on Queensland's Fraser Coast and has previously aspired to organising a festival of her culture
