It includes the major town of Gatton and a number of smaller centres including Laidley, Helidon and Withcott. The eastern parts of the district are part of the outer southern suburbs of Ipswich and Brisbane in the area of Greenmount.

To the northeast, where it passes south of Ipswich and Brisbane, it is bounded by Ipswich West, Ipswich, Moggill. To the east, it shares a boundary with the seat of Logan.

The electorate has been represented by Jim McDonald since the 2017 election. Pauline Hanson came within just 114 votes of being elected at the 2015 election with a 49.78 percent two-candidate vote.

Hanson's subsequent election to the Senate in 2016 precluded her from running in Lockyer again in 2017.
