If you have a mortgage in Australia, then the provider demands that you have insurance to cover the building. So if it's burnt down then you claim on the insurance, which will cover the cost of rebuilding. Naturally, you'll still be paying the mortgage, but you will also have your home repaired our rebuilt. Or if you can't rebuild then the insurance money would cover the cost of the house and you'd pay the mortgage provider whatever you owed them from that.

South Australia, the state that I live in, is actually moving forward quite well in many ways towards renewable energy and we have new regulations coming in to stop the use of single use plastics. This seems to be well received by most of the people here, which is promising.
