Human Services Minister Michael Keenan this evening expressed his disgust after seeing mobile phone vision of the incident which occurred Monday in an office in Adelaide’s northern suburbs.

Mr Keenan it was totally unacceptable and had asked his department to deliver ways to “help stamp out the thousands of incidents of aggression and violence faced by Centrelink staff each year”.

“Like most Australians I was disgusted to see video of somebody abusing my staff and women and children in one of our service centres in Adelaide,” he said in a statement.

“Unfortunately this is one of thousands of incidents of customer aggression that we get around the country on any given year.”

The video shows the man at Salisbury Centrelink demand from staff why they gave people from other racial backgrounds money but not him.

“I didn’t vote for multiculturalism did I?” the man screams as staff try to remove him from the building.

“But you will do whatever you can for every other c**t other than Australians.”

He threatens to “smash” staff as they attempt to shield customers and children who enter the building near the ranting man.

The man singles out a Centrelink client who is out of frame, calling her a “black b***h” and asking how much money she is receiving from the government welfare agency.

Before exiting the building the man yells a final obscenity and demand: “f*** youse all, you will pay me my f***ing money”.

Police have confirmed that a patrol attended the building at about 11.30am on Monday, after the man had left the premises.

Minister Keenan said: “It is completely unacceptable for the 35,000 people in my department to go to work and fear that they might be abused or assaulted in this way.”

Mr Keenan said he did not want to pre-empt what further police measures might look like, but said those who did the wrong thing were on notice that their behaviour would not be tolerated.
