Corby returned to Australia in July 2000. The couple's divorce was finalised in 2003. Returning home to Australia, Corby had a stopover in Bali, where she had been five times since the age of sixteen, which included stopovers on her way to or from Japan. Corby's older sister, Mercedes, was previously married to a Balinese man (who was Corby's parole guarantor) and lives in Bali. Arrest On 8 October 2004, Corby, her brother and two friends flew from Brisbane to Bali transiting in Sydney. It was her first visit to Bali in four years, having had several previous stopovers between Australia and Japan to visit her sister, Mercedes. Passing through customs upon her arrival at Ngurah Rai International Airport in Denpasar, Corby was stopped by customs officers and found to have of cannabis in a double plastic vacuum-sealed bag in her unlocked bodyboard bag. Customs officer Gusti Nyoman Winata said that she tried to prevent him from opening the compartment of the bag containing the cannabis. Corby denied this during the trial, saying she originally opened the bag after being asked by Winata whose bag it was. Corby said she and the customs official had difficulty understanding each other. No CCTV footage of this interaction was retrieved or preserved. Corby stated that she had no knowledge of the drugs until the bodyboard bag was opened by customs officers. Trial The prosecution case was based on the customs official's testimony that Corby said the bag was hers, and that it was found to contain 4.2 kg of cannabis. Four customs officials present when her bag was first examined in Bali said she tried to stop the bag being opened, and that she had said "I have some..." This provided a prima facie case for the prosecution. Three of Corby's travelling companions claimed in their testimony that they had seen her pack the bag before leaving for the airport and that only the flippers and yellow bodyboard were inside it. In contrast to the testimony of the customs officials, Corby said that she opened the bag herself at the customs counter. The Australian Government offered the services of two Queen's Counsel on a pro-bono basis. Alleged involvement of baggage handlers Corby's lawyers argued that she had no knowledge of the cannabis until customs officials at the airport found it. Her defence centred on the theory that she had become an unwitting drug
