Corby in Bali twice in 2005 – but only as a tourist offering support during her drugs trial. McCauley said he first met Corby at her court hearing in May 2005. He said Corby's mother invited him to visit Corby at Kerobokan Prison the following day. Despite claims that the photos had been taken prior to Corby's arrest, McCauley said the photos were taken at an empty fish pond at the prison where the two were permitted by prison guards to sit and talk.
