The by-election for ex-Prime Minister Kevin Rudd's former federal seat will be held on February 8.
Speaker Bronwyn Bishop announced the date of the election for the Brisbane seat of Griffith in a short statement on Monday.
The by-election was called after Mr Rudd, a two-time prime minister, quit in November, despite holding the seat at the general election in September.
Terri Butler, an employment and industrial relations lawyer, will contest the seat for Labor. Dr Bill Glasson, former president of the Australian Medical Association, who lost to Mr Rudd in September, will stand again for the Liberal National Party.
Boookie Sportingbet has installed Ms Butler as the favourite, at $1.18 against $4.25 for Dr Glasson.

"It's a two-horse race according to the odds but the money has been coming in five to one in favour of Labor and our punters are convinced Ms Butler can put the champagne on ice," spokesman Andrew Brown said.
