Corby must agree to snitch if freed Schapelle Corby in her cell at Kerobokan Prison, Bali. SCHAPELLE Corby will have to guarantee to help Indonesian authorities catch other drug traffickers before she can be released on parole. Kerobokan prison governor Ngurah Wiratna has revealed the Australian prisoner would need to sign up to being a "justice collaborator," meaning she would help narcotics police if required, before she could get out of jail. Mr Wiratna has met Corby's Indonesian lawyer, Iskandar Nawing, five days after the Australian Government brought her release a step closer by officially guaranteeing she would not leave Indonesia while on parole. The jail boss initially also said Corby would be required to admit her guilt before being eligible for parole, before later clarified his position after examining the detail of government regulations introduced last year. Australian Consul-General Brett Farmer also met the jail boss to discuss the next steps in Corby's parole process. Indonesian authorities been provided with letters from the Australian Government and Wayan Widyartha, the husband of Ms Corby's sister Mercedes, in support of her release. Mr Widyartha's letter says Corby would be welcome to live in his family home, he would provide "moral and material" support and he would supervise her to be a "responsible" person. Her lawyer said he was hopeful her application would be successful. I am optimistic about the parole. We will do our best," he said. Corby, 35, who was arrested at Denpasar airport in 2004 carrying 4.2kg of cannabis in a boogie board bag, has served eight-and-a-half years of a 20-year sentence, which now officially ends in 2017 after remissions. If released on parole, she would not be able to leave Indonesia until 2017. Mr Wiratna said a team of nine prison guards and two correctional agency staff would decide on Ms Corby's parole once all the administrative requirements were met. We have an internal monitoring team tasked to monitor all the inmates. The team consists of nine prison guards and two staff of correctional agency. For Schapelle's parole, once all the administrative requirement complete, the team will hold (a) meeting to decide whether she has (the) right to get the parole or not," he said. A spokesman for Foreign Affairs Minister Bob Carr said Corby's parole was now a matter for Indonesian authorities, but the Australian Government's guarantee provided the chance to present her case.
