Mr Miles has also announced that Labor's candidate for Inala will be local woman Margie Nightingale.

"I asked the state secretary to make sure that our candidate was a local, a woman and someone with community experience and Margie is all of those things," he says.

"She's lived in the Inala electorate all of her life, it's where she raised her two daughters.

"She lives in Forest Lake, she's been on the P and C of the Forest Lake State School for 18 years, she lived in housing commission in the electorate with her single mother.

"She was like me the first in her family to go to university, she got first class honours — I didn't get first class honours."

Mr Miles thanked both Annastacia Palaszczuk and her father Henry for their contributions as MPs for Inala.

Ms Nightingale is listed on LinkedIn as a senior policy advisor to the Queensland Treasurer.

This is where we'll leave today's live coverage.

Mr Miles has also confirmed a by-election for the southern Brisbane seat of Inala will be held on March 16, the same day as Queensland's council elections.

Inala was vacated by Mr Miles's predecessor Annastacia Palaszczuk when she formally resigned from the seat on December 31.

Over the weekend, the state opposition criticised the time being taken to announce a date for the by-election.

"Holding it on the same day as the council election isn't just more convenient for those residents, it will save us about $600,000 — that's what the cost of a standalone by-election would be — and it's based on the independent advice of the Queensland Electoral Commission," Mr Miles says.

The Queensland premier says transparency and scrutiny on the cost of supermarket goods and on the prices paid at the farm gate is "a key first step" in addressing how farmers are treated and in delivering cheaper groceries.

"While my 30-minute meeting with [supermarket bosses] was useful I think that kind of detailed scrutiny by the state's parliament is fitting for the kinds of concerns that we've heard from Queensland farmers and Queensland consumers," Mr Miles says.

Mr Miles says a committee will run the inquiry and will be formed in the first sitting week of the parliament.

"The supermarkets have also agreed to share more information with us and as much of that information that we can share with Queenslanders, we will.

"We'll put that information together in a way that is transparent for Queenslanders so they can get a better sense of why they're paying what they're paying at the supermarket."

Mr Miles has just confirmed an inquiry will take place, with terms of reference yet to be finalised.

He says he had productive meetings with senior executives of Coles, Woolworths and Aldi yesterday.

"They were good meetings and they were concerned about the concerns that I was raising with them,

"They all agreed to participate in that parliamentary inquiry."

Premier Steven Miles is speaking to the media about launching a parliamentary inquiry into supermarket pricing.
