THE Newman government will face the second major test of its popularity in as many months after announcing the date for the Stafford by-election.
The poll was sparked after the shock resignation of outspoken LNP member Dr Chris Davis.
Dr Davis was dumped as assistant health minister last month after speaking out over doctor's contracts and polling his electorate over the controversial changes to the Crime and Misconduct Commission.
Premier Campbell Newman told State Parliament on Thursday he had consulted Governor Penelope Wensley the previous evening of his plans.
"The reason for choosing July 19 is that it is the first Saturday after the July school holidays," he said.
"It also gives the people of Stafford time to hear from all parties about their plans, or in the case of the Australian Labor Party their lack of plans, for this state and its future."
Australian Labor Party candidate Dr Anthony Lynham is considered the favourite to win the seat.
The LNP has yet to select a candidate.
The Stafford by-election comes five months after Redcliffe by-election in which the government suffered a 17% swing against them.
The LNP won the seat of Stafford at the 2012 election by a 7.1% margin.
