The woman had been called to the school to discuss her son's behaviour after he was accused of harassing a girl in year 8.
A few days later : the mother told Bentley Park College principal Peter Krugle that if the situation between her daughter and a student was not resolved to her satisfaction she would "deal with it by (her) own hands".
He took this as a threat against the student.
The mother was told not to re-enter the school premises.
July 23 2012 : a staff member allegedly overheard students talking about a mother chasing them and wanting to hit them.
The teacher asked the mother to leave the school grounds.
The mother left the school grounds, but she then proceeded to yell from the footpath, "come out here and I smash you, c'mon, I don't care."
The mother told the teacher that the children had been "cheeky" to her and she would smash them.
"I'll go to jail, I don't care," the mother said.
July 24 2012 : after being told her daughter was being suspended, the woman allegedly went to the school and said: "I am going to hunt those girls down."
She then threatened to punch acting principal Kathryn Todd.
The mother was given a letter advising her that she was banned from the school's grounds.
"I am going to hunt those girls down, it may not be at school but I get 'em in Cairns," the mother responded.
"I'm going to f------ smash those little c----.
"This is because we are black".
The mother then left the school with her daughter but returned because her daughter had forgotten her bike.
While the mother was on the school grounds retrieving the bike, she called a teacher a "white c---" and told her she was going to punch her.
September 4 2012 : students told the deputy principal that they had been chased by the woman, her daughter and another relative, with the mother calling them "sluts", and they had run back to the school.
