Suggestion #1 - Building an Underground/Subway System

One of the criterion for Mercer's is the amount of public transport available. Adelaide is a beautiful city, and nothing is too far away, but we have a very poor public transport system. We have a few buses that go round the city, a couple of trams and a couple of trains, but apart from the buses - which aren't as easily accessed as they are in other cities - it is hard to get around the city without a car. Bigger cities in Australia like Melbourne and Sydney have an underground system, which is easy to access anywhere and has many trains so you can go almost anywhere at almost anytime. If Adelaide were to build a subway system it would make going around the city and to the outer suburbs a lot easier. We have enough space to build stations and many different places people would want to go that it makes sense to build an underground system. I think that just by doing this we could - or almost could - make it into the top ten most livable cities in the world, because transport is where we are having the most trouble.
