Remove rubbish, leaf litter and native shrubs close to buildings.
Form a wide firebreak around your home, eg short, green grass (use mower, spade, rake), trim branches well clear of the house. Clear roof and gutters of leaves, twigs etc..
Fit wire screens to doors, windows and vents, and enclose all gaps, roof eaves and the area under your house.
Store wood, gas, petrol, paint etc well clear of the house.
Keep ladders handy for roof access (inside and out). Fit hoses to reach all parts of the house and garden. If mains pressure water is not connected, obtain a high pressure pump.
Check you have adequate insurance cover for bushfire.
Agree on a household plan to leave early or stay to protect your home during a bushfire. If leaving, plan when, where, how you will go and what to take.
