Former icare general manager of compliance,fraud and corruption control Chris McCann told the upper house inquiry that he estimated there had been about 50 thefts over a six-month period in 2016 after the insurer's office was refurbished.
"It's hard to believe but overnight property such as tables,chairs,cushions,microwave ovens,television sets,iPads,toasters,kettles,crockery,knives and forks were going missing,"he said.
"Numerous reports were made to me about the theft of property from icare over a period of time."
Mr McCann,who in August blew the whistle on the toxic culture within the organisation in a joint investigation by theHerald and ABC TV's7.30,told the inquiry that people at the organisation"did not want to know about any bad news to deal with corruption".
The former homicide detective said there was no asset register within the office at the time,and when he suggested the matter be referred to police,he was told to ignore it. He added that several taxi cab charges had also been misused.
"I was told to drop it,I was told not to investigate it,not to waste my time on it,it was a waste of time and the amounts were inconsequential,"Mr McCann said.
"I said'It's not about the value,it's about what it's doing to the culture of this company internally,people having money stolen out of their drawers overnight'."
