Reported at www.abc.net.au: Keith Pitt officially resigned from his position as the Member for Hinkler, leaving the seat vacant with the next federal election approaching.

Experts suggest it is unlikely a by-election will be held before the election, as the costs and logistics would be impractical given the proximity to the upcoming vote.

The LNP is currently in the process of selecting a candidate for the general election while the Speaker of the House reviews whether a by-election should be called.
