THE viability of a 23-kilometre, $2 billion stretch of light rail is up for public debate.
Sunshine Coast Council has released the findings of initial feasibility studies into the infrastructure proposal.
The project, which would rely heavily on state government funding, was estimated to cost $90 million a kilometre to build.
The light rail would potentially service Caloundra South, one of three new areas that will hold 60% of the Coast's population growth by 2031, according to the council's $26,000 document.
How does this compare to the light rail costs for Canberra?
