During planning and construction, Ballajura station was known as Malaga station Constructing the Ellenbrook line by 2023 as part of the
Metronet project was committed to by the
Labor Party before it won the
2017 state election. The route of the Ellenbrook line was officially confirmed in August 2019. It had the line running in the median strip of
Tonkin Highway north from
Bayswater, exiting north of
Marshall Road to travel east, with Ballajura station located in the land bounded by Tonkin Highway, Marshall Road, and Beechboro Road North. The
A$753million main construction contract for the Morley–Ellenbrook line was awarded to the MELconnx Consortium, consisting of
Laing O'Rourke, in October 2020. Early works for Ballajura station were underway by August 2021, starting with the set up of site compounds. The first concept designs for the station were revealed in September 2021. The station was designed by lead architects
Woods Bagot. Initially, no footbridge to connect Ballajura station to its namesake suburb was planned, but in November 2022, it was announced that a footbridge would be constructed by the Tonkin Gap Alliance, the same alliance that was doing the enabling works for the Morley–Ellenbrook line along Tonkin Highway. The footbridge was a result of a community survey undertaken by Metronet in 2021. By November 2022, construction on Ballajura station's foundations was underway, and
piling for the Beechboro Road North bridge was complete. In mid-2023, the roof on the upper level of Ballajura station was being installed. Construction on the station and footbridge had finished by July 2024, when it was announced that the station would be named Ballajura instead of Malaga. The station and the rest of the line were officially opened on Sunday, 8 December 2024 by Prime Minister
Anthony Albanese, Premier
Roger Cook and Transport Minister
Rita Saffioti, with community events held at each of the five new stations. ==Services==
