Construction of the line started in February 2004. The contract for the city centre works, including the tunnels, was awarded to a joint venture of Leighton Contractors and Kumagai Gumi. The contractors used a Tunnel Boring Machine manufactured by Mitsubishi Heavy Industries. The first tunnel was completed on June 3, 2006, and the second tunnel was completed on October 27, 2006.
Between 2004 and 2006, the Leighton Kumagai Joint Venture (LKJV) was affected by a series of industrial disputes involving the Construction Forestry Mining and Energy Union. This culminated in the prosecution of 107 workers for taking illegal industrial action, by the Australian Building and Construction Commission. Prosecution of "the Perth 107" became a national and international cause celebre, in part because it occurred as the Federal Government's unrelated WorkChoices reforms were taking place. The government attracted criticism from the political left and union leaders around the world, including the International Labour Organization.
The line was proposed to be opened on July 29, 2007, but was not complete by that date.
From October 7, 2007 to October 14, a planned shutdown of the whole Fremantle Line and partial closure of the Joondalup Line between Perth and Leederville stations was undertaken to allow workers to connect the Mandurah Line to the Joondalup Line. On October 8 there was considerable publicity about delays experienced by commuters. This was mainly due to signalling problems associated with works for the shutdown week. As a result of the problems on October 8 and October 9, passengers on the Joondalup line were given free travel from first service until 8:00am. On October 15, the Perth Underground and Esplanade stations were opened. On this day, the railway also carried its first passengers with the extension of Joondalup Line services to Esplanade station.
On November 9, 2007, the first train crossed Narrows Bridge to Rockingham station, testing the new railway line at around 7:30am with a driver and a group of engineers. After the line testing completed, driver training was undertaken.
The line was officially opened on December 23 2007, with the first train carrying 1500 passengers, including 1000 members of the public selected by ballot. To celebrate, all Transperth bus, train and ferry services were free. On December 24 2007, new routes and schedules took effect on many services, including the Mandurah Line.
The line replaced bus services which previously travelled along the freeway to the city, which now terminate at Mandurah Line stations. The exception is Canning Highway services, which will stop at Canning Bridge station before continuing to the city.
A possible extension to Erskine might take place, to turn into Mandurah/Old Coast Road and turn off into Erskine.
The Mandurah Rail Depot, Perth is located immediately north of Mandurah station.
