A nursing graduate charged over the death of a woman after a botched breast cosmetic procedure was "simply following directions", her lawyer said.
Yueqiong Fu, 29, was charged with manslaughter, using poison to endanger life and hindering a police investigation over the death of Jean Huang.
Ms Huang, 35, went into cardiac arrest during a breast enlargement procedure at the Medi Beauty Clinic at Chippendale on August 30.
Ms Huang, who was the clinic's manager, was taken to Royal Prince Alfred Hospital where she died two days later.
Chinese national Jie Shao, 33, was charged with manslaughter over Ms Huang's death and was refused bail earlier this week.
Fu is the second person to be charged and made an application for bail when she faced Burwood Local Court today.
Her lawyer Neville Parsons told the court Fu was in Australia on a student visa and had recently received a degree in graduate nursing from the University of Technology in Sydney.
He told the court Fu studied nursing in China and had worked for three years in a Chinese hospital before moving to Australia with her husband.
Mr Parsons said his client believed Shao was a qualified doctor and she was simply assisting a medical professional during the procedure.
"Being a nurse, she is trained to obey what doctors tell her," Mr Parsons told the court.
"[Fu] believed she was dealing with a qualified doctor from China and she simply followed the directions of the doctor."
Mr Parsons said his client was willing to submit to house arrest and agreed to report daily to police accompanied by her father-in-law.
But prosecutors opposed bail, saying Fu was facing serious allegations and her student visa status could make her a flight risk.
"It will be alleged that she engaged in unlicensed, highly dangerous medical procedures in an unqualified capacity," the prosecutor argued.
"Given her status in Australia there is a concern that she may pose a significant flight risk."
A decision on whether Fu will be granted bail will be made later on Friday.
The Medi Beauty Clinic, located in the Central Park Mall on Broadway, near Central Station, has been closed since Ms Huang's death.
Its website advertises a variety of skin treatments, laser hair removal and anti-wrinkle injections.
"We can assure you that all of our treatments and equipment meet the highest industry standards and conform to all required legislation," the website stated.
