Singaporean national Nasuha Nasser, who resides in Melbourne, appeared before the Ballarat Magistrates Court on Monday. 

The 21-year-old woman has been charged with negligent driving causing serious injury and dangerous driving causing serious injury.

Police informant Detective Sergeant Mark Amos told the court that Nasser was allegedly driving a blue Renault along Madden Road in Cardigan at 8.15pm on November 24, carrying four passengers at the time.

Police allege she failed to stop at a T-intersection and collided with a white Triton travelling east on Remembrance Drive, carrying a 48-year-old man and his 10-year-old daughter. 

The court heard that impact was to the passenger side of the accused's vehicle. Post-impact, the informant said, both cars ended up on the north-east corner of the intersection, with Nasser's vehicle colliding with a tree. 

The accused appeared in the dock in a tie-dye rainbow shirt with mussed black hair and kept her head bowed during the bail application. 

Detective Sergeant Amos said an investigation by the Major Collision Investigation Unit of the scene revealed "no pre-impact braking from either vehicle", with the road dark but dry at the time. 

He said that blood samples had been taken from both drivers, which have not yet been analysed, but police have "no reason to believe there's drug or alcohol involvement at the moment". 

"Ms Nasser was interviewed yesterday evening. She was open, honest, and a full and frank discussion and account of events was provided," Detective Sergeant Amos said. 

The informant told the court that Ms Nasser said in a police interview she was aware "speed limits change" on country roads, but when she "became aware of the stop sign she was unable to stop". 

The court heard that 150 metres before the intersection on Madden Road, there is a sign notifying drivers of an upcoming intersection and stop sign. 

The police prosecutor opposed bail for the accused, but Detective Sergeant Amos told the court she would not be an international flight risk if she was bailed with a condition of no travel, but it was "terrible case with a catastrophic result". 

Magistrate Gregory Robertson granted the accused bail on the condition that Nasser surrenders her passport and any travel documents to police and she reports weekly to the Melbourne North Police Station. 

"On the basis that there's no risk of her fleeing, and given I accept that it was an oversight, not intentional or with aggravating features like her trying to kill people or run away from police ... I grant bail with some conditions," Magistrate Robertson said. 

Detective Sergeant Amos told the court that Nasser has an identical twin sister, but there were "security features involving biometric tagging by fingerprint", with notification to be submitted to Border Force so she could not leave Australia on a different passport. 

Nasser will return to the Ballarat Magistrates Court for a committal mention in February.
