Firebreaks prevent that fire jumps from one side to another but it can cause that erosion takes place. They used a bulldozer to clean the area for the firebreak. The whole way where the firebreak was done are straight and this is a better chance for erosion because it is a straight line and not a lot of twist and turns.

Description
The violet tree is a small to medium-sized tree that grows up to 6 m high, with characteristic pale grey, smooth bark. Leaves are variable in size and shape, alternate, often in clusters or crowded on dwarf spur branchlets which are sometimes spine-tipped. They have very fine hairs when young but they lose them as they mature. Flowers are sweetly scented, in short bunches, pink to purple and are produced in early summer. They are about 10 mm long and are each borne on a long, slender stalk (peduncle). Terminal and axillary sprays are about 30-50 mm long, appearing with the very young leaves. The fruit is round, with a distinctive membranous wing up to 40 mm long, purplish green when still young, becoming pale straw-coloured, and can be seen between April and August.

A way to make firebreaks.

Drip torches drip lighted fuel onto dry grass, and are mostly used for line or perimeter ignitions. As a management tool matches tend to be used primarily by Indigenous land managers for setting small scale, patchy fires. Capsule launchers propel incendiaries from a vehicle and are useful to widen firebreaks.
Aerial fires involve dropping incendiaries from aircraft. This type of approach is useful for remote areas which are difficult to access by road, and can be used to place strategic fire breaks to help prevent the spread of late season wildfires.
