The Independent Commission Against Corruption is investigating allegations that Mr Medich and the former boxer Lucky Gattellari offered rewards or inducements to former NSW energy minister Ian Macdonald to arrange meetings with state energy executives in July 2009.

Mr Medich and Mr Gattellari are charged with the murder of businessman Michael McGurk.

Kim Shipley, a former consultant to Rivercorp, an electrical contract company, told the ICAC that in September 2008, when the company was unable to meet its payroll obligations, Mr Gattellari, who was Mr Medich's business partner, arrived with $200,000 in cash in a Myer shopping bag.

Mr Gattellari said Mr Medich had provided the cash, Mr Shipley told the inquiry.

In other evidence, a former executive of Rivercorp, Tony Rowe, said that Mr Medich planned to use his "significant political and business relations" to further the interests of Rivercorp, into which he had invested millions of dollars.

Mr Rowe told the inquiry he spoke to Mr Medich at a Construction, Forestry, Mining and Engergy Union (CFMEU) fund-raiser in April 2009, and discussed potential work the company might obtain from the state government.

He said Mr Medich said to him: "I am particularly well connected so we should go OK with that sort of work."

In a statement tendered to the ICAC, Mr Rowe said that Gattelari had arranged for Asian girls to attend some of the dinners for the purpose of sexual favours.

He also said in the statement: "I was aware Medich had his own girl."

Earlier today, Mr Rowe said in a statement that Mr Shipley had also been involved in taking sexual favours but  later Mr Rowe asked the commissioner to cancel the part of his statement referring to Mr Shipley.

The inquiry has previously heard Mr Gattellari "collected and kept a group of young women ... for themselves and their guests".

The hearing continues.
