Mr Smith, who has been a member of parliament since 2001, said it was an "honour and humbling experience" to be elected again.

Prime Minister Scott Morrison on Tuesday praised Mr Smith for his "wise and calming presence".

"The normal passions in the heat of the debate that occurs in this place, you accept and you celebrate, but at the same time you temper us in those times when, of course, there is overreach," Mr Morrison told the chamber.

"But in this role, Mr Speaker, you also do something which I think is truly great ... you honour and you work so well with those who serve in this chamber and you lead them incredibly well."

Labor leader Anthony Albanese also heaped praise on Mr Smith, describing him as fair and impartial.

Mr Smith pointed out the House of Representatives was a place of debate, acknowledging his role in ensuring it occurred in a dignified, balance way.

"It's the arena where the battle of ideas and ideals takes place," he said.

"And it's right that it should be vigorous and passionate and robust."

He also flagged impending changes to behavioural standards during question time, which he described as political contest at its most intense.

Mr Smith was nominated by his colleague Lucy Wicks and seconded by Labor MP Maria Vamvakinou.

Keeping with tradition, Mr Smith was led up to the Speaker's chair by his two nominators in an act of feigned duress.

Historically, the Speaker was blamed for delivering bad news to the royals, leading to some being murdered, imprisoned or exiled.

Nationals MP Kevin Hogan and Labor's Rob Mitchell battled for the deputy speaker role, with Mr Hogan clinching the position.

Mr Hogan was first elected as deputy speaker in March last year, while Mr Mitchell has been the second deputy since the end of 2013.
