About half an hour after later, her 28-year-old former partner was allegedly hit by a car driven by a man dubbed "Menace", Majok Chol Majok.
The ex-boyfriend was now in hospital with life-threatening injuries after surgery that removed a large section of his skull, Brisbane Magistrates Court has been told.
Majok, 21, has been refused bail after being charged with a number of offences including attempted murder.
Police prosecutor Eddie Fraser said on Tuesday there was a "vile, protracted, vicious attack on the behest of a scorned lover".
Police allege a 23-year-old woman told Majok to "bring everyone" in a series of phone calls after her de facto partner ended their two-year relationship.
CCTV footage shows the woman punching the ex-boyfriend outside a West End bar in Brisbane's inner south about 1am on April 23 after she received a message from him confirming the split, police say.
It is alleged the woman rang Majok - who police believe has links with criminal gang Swish Bound Gorillas - and said: "Menace bring everyone, bring everybody".
The woman told another man to "come right now" during a number of calls after mentioning her ex-partner and that she wanted to "f*** his s*** up", police say.
Police allege Majok and four other men arrived at West End wearing balaclavas in a Mazda about 20 minutes later.
It is alleged CCTV footage shows the woman approaching the car and talking with the occupants for about 10 minutes.
She then walks toward her ex-partner who is with a group nearby before turning to the Mazda and shouting "OK", police say.
Majok allegedly then immediately got out of the car with the four others and ran toward the ex-boyfriend's group, threatening them with knives.
Police say Majok later drove into one of the ex-boyfriend's associates "at speed" after a co-offender stabbed the 27-year-old multiple times in the back.
Co-offenders punched, kicked and threw a shopping trolley on the ex-partner's 27-year-old associate as he lay on the ground "defenceless" after being hit by the car, police allege.
Majok is then accused of accelerating into the woman's ex-partner who allegedly hit the bonnet and tumbled over the vehicle's roof before the Mazda sped away.
Mr Fraser described it as a "deliberate and purpose-driven collision by the Mazda".
He said the ex-partner had since undergone several surgeries including a decompressive craniotomy "with the removal of a large section of skull".
He was in hospital with life-threatening injuries, the court was told.
Mr Fraser said the other victim was treated for three stab wounds.
Majok - who was on bail at the time - was arrested after a police search of his home on Monday.
He has been charged with attempted murder, affray, wounding and assault occasioning bodily harm in company.
Acting Magistrate Peter Cooke refused bail on Tuesday, with the matter set for mention on June 5.
