A court in Ipswich, Queensland, heard how a mother left her daughter in a motel room for a stranger to rape her, after he asked the woman to have sex with a "younger version of herself".
The 47-year-old woman was sentenced to four years in jail on Wednesday.
The daughter was a teenager at the time the events took place.
The woman took her daughter to a motel in Toowoomba, west of Brisbane, on the promise of a "girls' trip", fuelled by Vodka Cruisers, the court heard.
The woman left her daughter in the motel room for a stranger named "Thommo" to rape, while she waited outside.
"Thommo" had unprotected sex with the teenager, with the mother's consent.
The daughter, now an adult, broke down in court and said she would never forgive her mother.
'I've felt nothing but pain, anger… mentally numb as to how a mother can do this to a child," she said to her mother in court, the Sunshine Coast Daily reports.
"Words cannot express my loss of a childhood by your actions, your lack of compassion. Your actions will not, cannot be forgiven."
The 47-year-old pleaded guilty to procuring a young person (daughter) for carnal knowledge.
She reportedly called her daughter "a f***ing bitch" in court.
Her four-year jail term will be suspended after she serves 12 months in jail.
"Thommo" is yet to be arrested.
