No love was lost on the floor of Queensland parliament on Valentine's Day, but that didn't stop the state's politicians having a little fun.

The Liberal National Party's Gold Coast MP Michael Crandon started the, at times, light-hearted mood in the chamber, when he took to the floor sporting a new bushy beard.

"I lay upon the table of the house...." he said to rapturous laughter from both sides of the house.

"Calm down, calm down!

"The ladies like it!

"Happy Valentines Day everyone."

Premier Campbell Newman even got in the mood.

His public displays of affection with his wife Lisa are well documented in the state.

But the premier now says he can't travel to Ipswich because he fears its mayor may also want a little action from him.

Mr Newman made a speech congratulating the engineers of the Wivenhoe Dam for their operation of the dam in the recent floods.

Ipswich Mayor Paul Pisasale, who helped the city pull through the disasters from two years ago, said he'd kiss the premier for the good result this time around.

"And that is why I'll be staying away from Ipswich, particularly on Valentine's Day," Mr Newman laughed.

Treasurer Tim Nicholls tried to get a rise out of Opposition Leader Annastacia Palaszczuk.

He said he received an early Valentine's Day present from her when she apparently told a local radio station that: "The treasurer had been doing a very good job".

But Mr Nicholls wasn't predicting any perceived goodwill to last.

"I was expecting a card from her today, but I'm still waiting," he said.

The opposition spokeswoman for environment Jackie Trad, who's a prolific Tweeter during Question Time, didn't waste a chance to push her cause.

"This Valentine's Day share the love, not Queensland's uranium."
