They have livestock, which they had moved to a safe area while they defended the house. The CFS trucks had made a stand at the road, as is a fairly common practice, and the family concentrated on putting out spot fires from the embers blown across the road before they could develop into bigger fires. Between the two groups they saved the house. There’s a bit of damage, but they did also manage to save the heritage vegetable garden which is the pride and joy of the young adult son of the household. They wouldn’t evacuate, since they had all the right equipment to fight a fire, a good clear area around the buildings, and knew what they were doing. It probably helped that they have a large garden of succulents and cacti between the house and the road - one of the family is a collector, and likes to display her plants in a way that also enhances fire safety.
