Speaker Curtis Pitt has set June 18 as the date for the the state seat, which covers the North Burnett, Western Downs and Banana Shire.
"In choosing the polling date, I was mindful of the 2022 federal election, which was practically required to be held in May," Mr Pitt told parliament.
"I did not want to hold the Callide by-election during the federal election campaign period."
Callide covers a vast agricultural area, at least four major coalmines, a number of coal seam gas projects, and the Callide coal-fired power station.
Mr Boyce, a farmer and former boilermaker who sits in the Nationals party room, was first elected to Queensland parliament in 2017.
He broke LNP ranks last year to vote against a Labor government bill to set up a mine rehabilitation commissioner, and has consistently supported coalmining.
Mr Boyce also spoke out against the Morrison government's net zero emissions pledge, and said it was not legally binding.
"It leaves us wiggle room as we proceed into the future. Morrison's statement that he has made is not binding," he told the ABC while on the campaign trail in April.
Mr Boyce succeeds retiring LNP MP Ken O'Dowd in Flynn, which covers Gladstone and the Central Highlands, after seeing off Labor's Matt Burnett in Saturday's election.
Nominations for the Callide by-election close at noon on May 31.
