"Labor had sex with Queensland for the last decade", according to Queensland Parliament's ethics committee leader.
Liberal National Party MP for Redlands Peter Dowling jumped to the LNP's defence on Twitter after Treasurer Tim Nicholls tweeted a photograph of himself and the Queensland Premier Campbell Newman drinking whisky on the Gold Coast on Thursday night.
Leanne Donaldson, Labor's candidate for the seat of Hinkler, quipped: "Are you celebrating screwing over Queenslanders?"
Mr Dowling replied: "No. We are getting Qld back on track! Labor had sex with Qld for last decade or more. Your bad."
His comments have been described as "childish at best" by Australian Christian Lobby state director Wendy Francis.
The MPs tweet came only hours after Mr Nicholls was forced to apologise to Queensland opposition leader Annastacia Palaszczuk for a "sexist juvenile taunt".
Ms Palaszczuk found herself at the centre of sexual innuendo when she was grilling Mr Nicholls on the state's finances during Wednesday's session of parliament.
She asked whether there would be any tax rises in June.
Mr Nicholls replied he was delighted to finally get a question from the opposition relevant to his portfolio, 403 days since the election.
"It is my first time with the leader of the opposition and I am excited by it," he said.
Ms Palaszczuk said she and Queenslanders deserved better from the government.
"Sexist, juvenile taunts are not acceptable anywhere, let alone on the floor of the Parliament," she said.
"I can take a joke but this was completely inappropriate and I'm sure all Queensland women would be offended that their elected representatives would be carrying on in such an undignified manner."
