When you look at total installation costs:

Wind and solar are much cheaper. Not only is the fuel free and faces no regulatory risk — in the form of a carbon price — but the technology is simpler and quicker to install.
Australia's chief scientist Alan Finkel went one step further. He factored the extra costs of adding gas or battery backup to ensure stability or baseload power in the system.
Wind still came out cheapest, with solar only marginally more expensive than black coal.
