Population distribution

Australia's population is primarily distributed along the east coast, with the distances between cities close enough to one another to make HSR a viable alternative. However, outside of the proposed route between Brisbane and Melbourne, HSR loses viability as distances become too great and passenger transit is lower. Projected population group further supports the viability in eastern cities as most development will be coastal and the boost to regional centres from the support of the HSR will lessen the effects of sprawl and congestion on the major cities.
