The footage, taken from police body-worn cameras and played during Brianna Lenehan's sentencing hearing in Wollongong District Court on Friday, captures the full five-minute interaction between Brianna, her 18-year-old brother Jason and a group of police officers, who arrived at the pair's Tucker Avenue home just after 9.30pm on August 14 last year after neighbours complained of being threatened by the pair earlier that night.

The video shows officers initially speaking to Jason at the front door, informing him of the complaint and advising him he was under arrest.

Jason then calls his sister, who immediately comes to the front door, wearing only a towel wrapped around her midriff.

"He ain't under arrest, he hasn't done nuffink (sic)," she boldly declares.

"We've been sitting here all night doing nothing."

Police then ask Brianna for her name, to which she responds, "my name's Brianna Lenehan, look me up on your f--king system".

She then tells them "I'll take my shirt off and I'll take all of yous on, cause he ain't done nuffink."

Police then inform Brianna she too is under arrest, prompting her to move towards the officers while yelling "do you think I give a f--k, do you think I give a f--k?"

Meanwhile, Jason asks the police to let his sister get dressed before she is taken away. Brianna disappears back into the house, followed by Jason and the officers.

The footage shows one of the officers step into the kitchen where he immediately yells "put the knife down, we've got a knife, we've got a knife!"

The officers draw their tasers as Brianna steps out into the hallway, brandishing a knife in the air and repeatedly yelling "[you] ain't gonna to taser me dog".

Brianna then lunges at one of the officers, cutting his hand with the blade before she is hit with a taser, causing her to fall to the ground and drop the knife.

During the next few minutes as Brianna is handcuffed and searched, she repeatedly yells she had done nothing wrong, asks why they arrested her brother and tells police they're going to get in trouble because she has been diagnosed with post-traumatic stress disorder.

She also repeatedly advises them she is Aboriginal, calls the officers "dogs" and says "this is my land", over and over again.

Both Brianna and Jason were arrested and taken to Wollongong Police Station.

Jason was subsequently charged with intimidation, while Brianna was charged with wounding a person with intent to resist arrest, assault and intimidation.

Brianna was remanded in custody and ultimately pleaded guilty to the charges.

In court on Friday, the 23-year-old admitted she had been hopelessly drunk that evening and had no recollection of what she did.

"I don't really remember doing it but it know I'm responsible for the actions I displayed," Brianna said.

"Does watching the video jog your memory?" defence lawyer Elizabeth Parkes asked her.

"No, it was just embarrassing," she replied.

"I just black out and can't remember. If I wasn't on alcohol I would have gone about it in a different matter. "I'm sorry I done what I did."

Judge John Hatzistergos will sentence Brianna on Monday.
