For the second consecutive federal election, it's all eyes on the seat of Gilmore.
It has been held by the Liberals or National party since it was created in 1984, that is except for one Labor stint in 1993.
Last time around, Liberal MP Ann Sudmalis, first elected in 2013, was locked in a battle with Labor's Fiona Phillips.
And while Ms Sudmalis is not recontesting the seat, Fiona Phillips is - and the bookies have installed her as the pre-poll favourite ($1.30) ahead of the Libs Warren Mundine ($3) and The Nationals' Katrina Hodgkinson.
With the Liberals' clinging to a margin of 0.7%, the seat is on the proverbial knife-edge.
Some pundits have suggested that boundary changes have played a significant role in the state of play.
Here's the state of play - on a two-party preferred basis as it stands before the 2019 federal election.
Gilmore is a relatively young electorate - created in 1984, it has had just four representatives.
And it's no surprise that the three living former federal members for Gilmore will support Nationals candidate Katrina Hodgkinson this time around.
There obviously has been movement at the station since 2016, most notably the change of the shape of Gilmore's boundaries.
The Australian Electoral Commission, an independent statutory authority, oversees the redistribution process and the motivation is to largely reflect changes in population.
Here's how the Gilmore electorate has changed since the 2016 poll.
