a revised patronage of 1,800, when factoring in the removal of the tunnel in Rockingham, and new land use data, but not the change in route from the Armadale line. The master plan gave another revised patronage, factoring in the removal of the tunnel in Rockingham and the rerouting of the line as a more direct route, as 2,060. Furthermore, the plan called for the railway line between Perth and Waikiki to be opened by December 2006, and the railway line between Waikiki and Mandurah be opened by December 2007, leaving Waikiki station as the line's terminus for a year. For the construction of the railway to Mandurah, among other rail projects in Perth, New MetroRail was set up as a division of the Public Transport Authority. The design and construction of the Mandurah line was split up into eight "packages". Among the things that were part of Package A was the bulk earthworks for several stations on the line, including Warnbro station. The $310 million contract for Package A was awarded to a joint venture between John Holland, MacMahon Contractors, and Multiplex Constructions Pty Ltd on 23 May 2004. The actual construction of Warnbro station, along with Mandurah station and Rockingham station, was part of Package C. Warnbro station was designed by Jones Coulter Young Architects and Taylor Robinson Architects. The design contract was awarded to Jones Coulter Young in April 2002, at a cost of $2.5 million. During the design process, the car park footprint was changed, as a important ecological community was identified north-east of the station, where part of the car park was planned to be built. Instead, the car park was extended south to cover an area of degraded bushland. Expressions of interest for the construction of Package C opened in September 2003. The $32 million contract for building Warnbro station and Rockingham station was awarded to a joint venture between Doric Constructions and Brierty Contractors in June 2005. Brierty did the civil works, and Doric did the construction of the station. $15 million from that contract is for Warnbro station. Construction on the station began in August 2005. The station was completed and handed over to the Public Transport Authority on 9 March 2007. It opened along with the rest of the Mandurah line on 23 December 2007. In 2010, 132 more parking bays were added to the station. In 2013, a $4.5 million
