Yes there is plenty of land. Lets all start a city out in the middle of the Simpson Desert - I will be expecting all of you to move there as you will be able to get a really cheap house and land package.
Can't build on all of the land where the current cities are you know as some land is needed for food production and most cities are located on what was some of the most productive land in the country. No you are right lets build on it all then you will all be complaining about the sky rocking food costs and that we have to import more and more of our food.
