A senior Queensland MP could be called on to explain "inappropriate" hand gestures he made in State Parliament.

Opposition health spokesman John-Paul Langbroek was grinning when he made one gesture, before touching his forehead in another.

It was made during a speech by the LNP's deputy leader, Deb Frecklington, but not long after Treasurer Curtis Pitt riled up Opposition MPs with a post-budget speech.

It also came just moments after Speaker Peter Wellington warned another Opposition MP not to use hand gestures to provoke the Government.

"It is a little bit over the top at the moment," Mr Wellington warned.

At a press conference five hours after the matter was raised, Opposition Leader Tim Nicholls said he had not had time to watch the five-second video of the gesture.

"I expect all MPs to maintain an appropriate behaviour in the house and I'll be reinforcing that to all of the LNP MPs," Mr Nicholls said.

Earlier, Education Minister Kate Jones told the House she would be writing to the Speaker over the "unparliamentary and inappropriate hand gestures".

"Mr Speaker my concern is that the Member for Surfers Paradise immediately disregarded your ruling and as such, I believe it is a reflection on the chair," Ms Jones said.

"The Member for Surfers Paradise should explain his actions and whether indeed they were directed at the Speaker, a Government member, or his own Opposition member."

As Ms Jones took her seat, one Opposition MP yelled across the chamber: "frivolous".
