So you have thousands of dollars worth of insulation because you live in an arctic climate. Congratulations I suppose. Now instead of just spending hundreds of billions on building a new grid Australians will also have to spend hundreds of billions on insulating their houses.

To be completely honest, they probably should, and people don't talk enough about proper insulation regardless of the region. E.g. in colder climates many modern buildings are just hermetically sealed boxes with issues around CO2 levels etc.

For a 14C differential you don't need insulation, you just need to seal leaks.

    If your house had problems with condensation forming on the outside then I hope it never rains where you are.

      Water in liquid form (e.g., rain) will (mostly!) go down with gravity, and so overhangs will help a lot, as will proper grade sloping away from your foundations.
