Federal government frontbencher Christopher Pyne has lambasted Labor for disrupting parliament with "undergraduate" and "ungentlemanly" behaviour.
Labor repeatedly disrupted proceedings in the House of Representatives on Wednesday night, after the coalition earlier used its numbers to gag Opposition Leader Bill Shorten.
Labor repeatedly called for a quorum as coalition members delivered their speeches in response to the address the governor-general delivered on the first day of the new parliament last year.
"They were being rude not only to the members but also to the governor-general," Mr Pyne, the leader of government business in the lower house, told ABC radio on Thursday.
Mr Pyne acknowledged that the coalition was a "robust" opposition in the last parliament.
"(But) we never descended into the undergraduate and bad-mannered and ungentlemanly behaviour that Labor descended into yesterday," he insisted.
Mr Pyne holds the record as the most ejected federal politician and the last parliament was considered the most disrupted in Australian history.
"Well, a hung parliament is a very unique beast in politics," he said in his defence, adding the last government was illegitimate because it was determined by rural independents in conservative seats.
But leader of opposition business Tony Burke laid blame for the parliamentary chaos squarely at the government's feet.
He said the government should not have used its numbers to put a stop to a planned debate on job losses in the NT.
"If they think they can silence the Labor party when it comes to defending jobs, as they discovered yesterday they've got another thing coming," Mr Burke told Sky News.
Independent MP Andrew Wilkie blamed both sides and said their behaviour was juvenile and self-indulgent.
"No wonder so many Australians are sick of politics, politicians and the political parties," he told reporters.
"Politicians should be leadership figures in the community, unlike a pack of clowns, which is how most politicians looked in the House of Representatives yesterday."
