Details of the incident have emerged as two officers were found to have committed serious misconduct.
On April 20, the pair stopped a 24-year-old student and her stepmother. They are both members of the Muslim Afghan community.
They said this was due to the stepmother not wearing a seatbelt, while they then criticised the driver for not stopping swiftly when they pursued: bringing multiple driving violations against her.
When the car was stopped, one of the policemen, named only as "Officer 1", told the driver: "You have to be the most stupidest [sic] person I’ve met as a driver of a motor vehicle with a police vehicle all the way since Church Street to here."
In the exchange, which was caught on bodycam footage, he then turned his attention to the stepmother, named as "Mrs R", and asked for her ID.
When her daughter, named as "Ms Y", explained she did not have any on her, the officers insisted both women get out of the car.
Officer 1 shouted at Officer 2, asking him to "whack the cuffs on Ms Y", a report detailed.
Officer 2, speaking to Ms Y, said: "If you don’t know how to drive on Australian roads, hand your licence back."
She had said she did not know where to stop and responded: "No, I swear."
Officer 2 asked "what's your religion?" and then said: "OK, swear to Allah."
The woman replied: "I swear to Allah, I didn't know."
Officer 2 said: "Yeah, right."
The pair then tried to instruct the daughter to try and get her stepmother's passport, while her visa status was questioned.
Officer 1 went on to say: "Don't take advantage of our system."
He also told the woman: "Don’t get aggro with me or you’ll be in the back of a divvy van going back to the gaol."
In submissions to the report, Officer 1 said he was "embarrassed" by the exchange, the report said.
But it added he "made no effort to apologise".
He said he "could see how" his behaviour "could be seen as bullying" but denied he had attempted to do so.
Officer 2 said he would like the opportunity to apologise to the women and said: "I was rude."
He said PTSD in his line of work had affected him.
Australia's Law Enforcement Conduct Commission determined both officers should not be on frontline duty where they interact with the public.
On Officer 1, it said: "Officer 1 is presently unfit for purpose as a police officer who has any contact with members of the public in his present mode of operation."
Officer 2 was also deemed "unfit for purpose" in his role.
It said: "He is ignorant of his duties and responsibilities. He admits to being rude and arrogant in the ordinary course of his duties when he decides a person may not be truthful.
"He should not be in further contact with members of public in the meantime."
