South East Queensland’s population is projected to increase by 2 million people between 2015 and 2041. Under current Queensland Government plans, much of this growth will be accommodated in the south-west of the region. The Logan Local Government Area (LGA) is expected to accommodate an additional 277,300 people by this time, and the Scenic Rim LGA is expected to accommodate an additional 22,200 people, bringing its population to 62,000. Further growth beyond 2041 is anticipated.
Without improvements to public transport, much of the associated growth in transport demand from this area will need to be accommodated on a road network that will become progressively more congested. Unless a corridor for improved rail transport is protected, opportunities to provide sufficient rail capacity could be ‘built out’.
The 54 km proposed corridor would link Salisbury to Beaudesert in Brisbane’s south-west region. The corridor largely aligns with the existing interstate rail line between Salisbury and Kagaru. The initiative aims to provide electriﬁed passenger rail services, with 11 new stations, and additional space for duplication of the existing interstate freight line. A cycleway is also proposed along the corridor.
The initiative is close to the alignment for a section of the proposed east coast high speed rail line (also a corridor protection initiative on the Infrastructure Priority List). Subject to further design development, the initiative could be adapted to provide sufficient space for a high speed rail line.
The Australian Government and Queensland Government are jointly undertaking a business case to determine the rail requirements in the Salisbury to Beaudesert corridor. The business case will conﬁrm the strategic objectives and issues within the corridor and identify potential options for corridor preservation and staging of investment.
