Convicted Australian drug courier Renae Lawrence could escape fresh charges despite being accused of plotting to murder at least one female prison guard at Bali's notorious Kerobokan jail.
Lawrence, the only female member of the Bali Nine, was moved to another prison in West Bali on Saturday after the alleged plot came to light following an unrelated raid on the women's cell block in Kerobokan that turned up a number of phones as well as weapons.
Details emerged on Sunday afternoon of the contents of text messages sent between Lawrence and another female prisoner, Joaninha Maria Sonia Gonzales, who the Australian had ordered to carry out the hits.
"Use the knife, use the metal chains," a message from Lawrence to Gonzales said, according to Kerobokan jail governor Gusti Ngurah Wiratna.
Gonzales, also known in the jail as "Black Sonia", allegedly responded with: "I will do anything you say. I am used to being in and out of prison. You only die once."
Mr Wiratna said the messages found in both phones clearly indicated Lawrence and Gonzales had been plotting "the murder of two female guards".
"At first she (Lawrence) denied it but after we showed her the evidence in her phone, she couldn't deny it," Mr Wiratna told AAP.
A blade was found in Lawrence's cell while another "commando knife" was discovered in the cell belonging to Gonzales.
But Mr Wiratna later suggested Lawrence could escape serious punishment, including charges of conspiracy to commit murder.
Mr Wiratna said he would not be referring the matter to police and would instead write up the alleged plot as a "violation of prison rules".
Gonzales is an East Timorese inmate charged with kidnapping a baby from a French family in Bali.
Lawrence is serving 20 years for her part in a 2005 plot to smuggle more than eight kilograms of heroin from Bali to Australia.
The 36-year-old from Newcastle - recently described by Mr Wiratna as a model prisoner - has received more than two years in remissions and had about 10 more years to serve.A spokesman for the Department of Foreign Affairs and Trade told AAP consular officials in Bali will meet Indonesian authorities to discuss Lawrence.
