KEY POINTS:
Swedish-born waitress and socialite Charlotte Lindstrom has admitted soliciting the murder of a witness in her boyfriend's drugs trial.
But the 23-year-old will only be sentenced on one charge, after the Director of Public Prosecutions (DPP) agreed to a plea bargain.
Lindstrom on Wednesday fronted Sydney's Central Local Court on five charges, including two each of soliciting and conspiring to murder crown witnesses.
She was accused of offering $200,000 to an undercover policeman to kill two men who were scheduled to give evidence against her boyfriend Steven Spaliviero in the NSW District Court.
Lindstrom allegedly told the operative that Spaliviero wanted the men in the "cemetery", and that it should be made to look like a botched armed robbery.
Lindstrom handed over information, including handwritten descriptions of the men, as well as a photograph with their faces circled, and a map of the location where they were to be killed.
She also promised to hand over a $10,000 deposit prior to the murders being carried out, police alleged.
But Lindstrom pleaded guilty to just one count of soliciting to murder.
Her lawyer, Philip Stewart said the plea was the result of "discussions" with the DPP.
"I can confirm that this was a legitimate plea bargain," Mr Stewart told AAP.
Mr Stewart said he expected the four remaining conspiracy, solicit and drugs charges would be dropped, provided Lindstrom adhered to her guilty plea in the Supreme Court.
She will have served nine months by her expected February 2008 sentence date, and Lindstrom would also give evidence against Spaliviero and other co-accused, Mr Stewart said.
This, along with her strict protective custody conditions, would be taken into account in sentencing, he said.
"One anticipates that if she gives assistance to authorities that she will be given the appropriate treatment, in accordance with established principles of law," Mr Stewart said.
Dressed in prison greens, Lindstrom smiled cheerfully as she appeared via videolink, saying "thank you" as Magistrate Allan Moore committed her to the NSW Supreme Court to affirm her plea on Friday.
Mr Stewart said Lindstrom was in good health, but would not see her parents for Christmas.
The Lindstroms have previously travelled to Australia to support their daughter in court.
Mr Stewart also said it was unlikely Lindstrom would have the option of serving any jail term in her native Sweden.
Lindstrom will appear in person for arraignment in the Supreme Court on Friday.
