Using a whipper snipper, cut back long grass along fence lines. It's a good idea to do this in winter or spring before the grass gets too long.
Churning up dirt ensures that fire may be less likely to creep across the grass. Simply attach the tiller attachment to your whipper snipper and chew along the grass. Your council will tell you how wide your firebreak needs to be. Ideally it is big enough to protect your property and provide access for a vehicle.
Firebreaks don't always have to look barren. Use a vegie patch or garden beds to create nice looking breaks. You will have tilled the earth so it's not going to burn.
