Prosecutors have alleged a Queensland barrister provided cash, meals and "sexual services from prostitutes" to then Ipswich mayor Paul Pisasale in return for assisting a property development.
Sam Di Carlo, 66, faced the first day of evidence at his trial on one count of official corruption in Brisbane District Court on Thursday.
In her opening statement, crown prosecutor Sarah Farndon told the jury that Di Carlo had a friendship with Pisasale while he was mayor of Ipswich and both men became involved with Melbourne property developer Chris Pinzone.
