Delight among Coalition MPs over Prime Minister Malcolm Turnbull's question time attack on Opposition Leader Bill Shorten has led to a second day of insults, with Deputy Prime Minister Barnaby Joyce accusing Mr Shorten of confected outrage and creating class warfare.

Mr Joyce said he had the best seat in the house for the spirited speech in Parliament on Wednesday, which has buoyed the spirits of the government's backbench and left Labor on the backfoot on Thursday.

The Nationals leader said Mr Shorten knew what he was doing in attacking Mr Turnbull's wealth, "creating this class warfare, calling Mr Turnbull 'Mr Harbourside Mansion' ", an insult coined by Tony Abbott confidant Peta Credlin.

He said he'd rather have leaders with money and success running the country than someone "with the arse out of their pants who has never made a buck".
