A woman whose partner allegedly killed her two-year-old daughter has admitted to smoking marijuana and having sex with the man on the day the young girl died.
Peta-Ann Francis, 28, appeared in the Mildura Magistrates Court in north-west Victoria on Tuesday as part of a committal hearing for John Torney, 31 - who is charged with killing Nikki Francis-Coslovich.
While fronting the court for more than three hours, Ms Francis admitted she bought marijuana on the morning of her daughter's death because she was 'anxious', and left Torney at home alone with young Nikki, according to the ABC.
'I wanted to go get drugs and didn't want her with me,' she told the court.
The 28-year-old also told the court she smoked the drugs with Torney when she returned, and the couple later had sex. The two-year-old girl's body was found stashed in the ceiling on Ms Francis' home in north-west Victoria on August 25, 2015, her body covered in bruises and dust.
She had been reported missing just hours earlier.
Ms Francis told the court she had been planning to leave Torney in the weeks leading up to her daughter's death.
'I was going to leave him, because of all the shit I put up with, him drinking all the time,' she said, according to the ABC.
The young mother also said she did not tell police investigators the entire truth when the arrived at her home because she was in shock, and 'was too concerned about where (her) daughter was'.
Ms Francis has three other young daughters.
It comes after the court heard on Monday Torney had screamed at the sobbing toddler on the day of her death.
A committal hearing in which Torney stands accused of the little girl's murder heard that neighbours saw Torney threatening his stepdaughter on the day before and the day of her death, News Corp reported.

Prosecutor Gavin Silbert QC told Mildura Magistrates Court on Monday that one neighbour saw Torney standing over the crying girl and saying 'Shut the f*** up you little c***'.
Mr Silbert told Magistrate Margaret Harding that Torney allegedly later told the neighbour that he occasionally felt like harming the little girl.
'She does my head in,' Torney allegedly said. 'Always crying. Sometimes I feel like belting the s*** out her.'
Police entering Torney's Mildura home noticed dirty finger marks on the manhole cover in the ceiling, and searched the cavity to find the two-year-old's body.

Another neighbour told the court they heard a male adult on the day Nikki died screaming 'no, no, no'.
Torney, who had previously been treated for anger management issues, had been living with Ms Francis since around May last year.
Ms Francis had split from the girls' father, Nick Coslovich, after their seven year relationship ended.
Victoria's Department of Health and Human Services had received at least four notifications relating to Ms Francis's four young daughters, but none of them related to Torney and the family had been given the all clear last July.
A post-mortem examination of Nikki Francis-Coslovich's body found she died from internal blood loss resulting from blunt force trauma.
The committal hearing continues.
People in the town of Mildura released balloons at a vigil following the murder of Nikki Francis-Coslovich who, a court heard on Monday, was screamed at before she died by stepfather John Torney's who allegedly said he sometimes 'felt like belting her'
