An attended house has a 70% better chance of survival than an unattended one.
Fill the gutters with water (block with tennis balls or anything else the works and is removable) and wet as much as possible use anything you can to store water a bath kids pool what ever as when the big red trucks turn up they will suck the mains dry so there may not be water for your house.
Rake up leaves away from the house and block up any openings because its not the fire you have to worry about its ember attack small glowing particles blowing in the wind they can get under eaves or under the house or in open windows so be aware of this.
Another one i have seen cause problems even with well prepared homes is the door mat those coir fiber mats burn well.
If you have an empty weed and feed bottle these are great if you buy black and gold dish washing concentrate about $1a bottle put one of these in the weed and feed bottle and fill with water then hook it on your hose and spray it will put a blanket of foam out which basically is stopping the water from running off or soaking in it can help a lot.
I hope this helps a bit
