Whistler bundled out of parliament

A man wearing army fatigues has been physically escorted from the public gallery of parliament's lower house after whistling at Bronwyn Bishop.

The man interrupted Treasurer Joe Hockey, who was answering an opposition question on the planned Medicare co-payment on Tuesday.

He whistled at Ms Bishop, who is the Speaker of the House of Representatives, before telling her he wanted to be heard on an issue of concern to him.

When confronted by security officers, the middle-aged man sat down and refused to leave.

It took three officers to escort him from the chamber.

The man, who gave his name as John Stayte from Queensland, was later questioned by Australian Federal Police outside Parliament House.

He told AAP he intended to file a police complaint against MPs he believed were "abusing" their power.

"These people are acting beyond their legal authority.

"It's bulls***."

Asked why he disturbed parliamentary proceedings, the man said he had alerted the Speaker about his intention to do so beforehand.
