New corridor alignment maps have been unveiled for a proposed multibillion-dollar rail line on the Sunshine Coast, marking a significant step forward in the region’s transportation infrastructure. The maps, released by the Department of Transport and Main Roads (TMR), detail the train route and associated infrastructure between Beerwah and Birtinya, part of the ambitious project known as The Wave. This initiative aims to enhance public transport in preparation for the 2032 Olympics.
The project is divided into multiple stages, with Stage 1 featuring a 19-kilometer line from Beerwah to Caloundra, and Stage 2 extending 7 kilometers from Caloundra to Birtinya. A future Stage 3 is planned to incorporate metro buses traveling approximately 18 kilometers between Birtinya and Sunshine Coast Airport via Maroochydore. The rail corridor was initially protected in 2001, with a detailed business case completed in 2023.
Modern Design and Environmental Considerations
Proposed refinements to the corridor have been made to align with modern rail design standards, optimize operations, accommodate a dual-track system, and minimize impacts on surrounding areas. The track is designed for speeds up to 160 km/h, potentially making it one of the fastest lines in the state’s southeast. It will connect to the North Coast line at Beerwah, providing commuters a 45-minute faster journey to Brisbane compared to driving.
The latest maps illustrate five stations—Beerwah, Bells Creek, Caloundra, Aroona, and Birtinya—and their surrounding areas. The route cuts through various natural and urban landscapes, including a 1.2-kilometer tunnel at Little Mountain. To address low-lying terrain and environmental sensitivities, the line will be elevated in several locations, featuring 16 bridges across roads, creeks, and the Bruce Highway.
“The refined corridor and reference design have been carefully developed to minimize impacts wherever possible, while also preserving the ecological value of the area,” TMR stated.
Community Engagement and Design Enhancements
TMR has engaged with the community to refine the alignment and minimize environmental, cultural heritage, and community impacts. Changes include adjustments to the active transport alignment, improved facilities at stations, noise mitigation measures, and unique design considerations for each station based on local community needs. Public art and urban design enhancements are also planned, along with improvements to the Sunshine Coast bus network at all stations.
Further details, including precise track locations, will be revealed as the project progresses. “Project maps will be further refined after contracts are awarded and detailed design is undertaken,” TMR stated. The project is currently in the pre-delivery phase, which involves developing the design, conducting environmental referrals, market sounding, and undertaking procurement.
Financial and Construction Milestones
Stage 1 is estimated to cost between $5.5 billion and $7 billion, with both the state and federal governments committing $2.75 billion each. Funding for Stage 2 will be considered as designs and plans are further developed. Contractors for Stages 1 and 2 are expected to be appointed early next year and by late 2026, respectively, with construction anticipated to commence in late 2026.
However, the project is not without its challenges. Scores of homes are expected to be resumed, although the exact number remains undetermined as corridor investigations continue. “We acknowledge this can be a challenging time and thank impacted property owners for their ongoing engagement as we work to deliver this key transport project for the Sunshine Coast,” a TMR spokesperson commented.

Sunshine Coast News has reached out to TMR for further information regarding the corridor alignment and is awaiting a response. As the project advances, it promises to reshape the region’s transport landscape, offering a faster and more efficient connection to Brisbane and beyond.
