The population of South East Queensland (SEQ) is expected to grow by 2 million between 2016 and 2041.
A large proportion of this growth, around 250,000 residents, is projected to occur in the region's south-western corridor, which includes the Salisbury to Beaudesert corridor. This growth will increase demand for reliable and high capacity passenger transport connections.
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’.
