Bushfire Mitigation

To minimise the potential risks of fires, the Shire uses a number of methods of mitigatation. These activities include building firebreaks, chemical and mechanical treatments, as well as reducing fuel loads and hazard reduction burns.

Planned burning can be an effective way to reduce vegetation from an area, copying a natural bushfire at much cooler conditions that are easier to manage. This treatment method is carried out to protect life, community assets and infrastructure, as well as to protect natural resources and species from damage from bushfire by reducing the vegetation fuel load within City managed reserves. Planned burning is done under cool burn conditions with experienced personnel onsite to monitor the burn intensity.


  • Can cover a much larger area faster than other treatments, creating a mosaic of burnt and unburnt areas for fauna to remain in the area.
  • A way to remove areas of invasive species and encourage the growth of native species from seed stored in the soil.
  • Low cost.


  • Weather conditions can change and increase the intensity of the burn, potentially impacting local flora and fauna.
  • There may be burning material, smoke and ash in the area during the burns and for several days following the burn.

Herbicides are applied to weeds with direct, targeted application. This treatment can also be used to prevent the germination of invasive species to encourage the growth of native plants. This treatment is most effective when combined with mechanical treatments or applied after a planned burn.


Can be applied on steeper slopes and target individual plants or larger areas, if required.


  • Limited by wet weather and not recommended in environmentally sensitive areas.
  • Only approved chemicals can be used and applied by a licenced operator.
  • Can be costly.

Mechanical treatments can be used to target specific areas and plant types while avoiding sensitive areas. Examples of mechanical treatments used by the City includes slashing, mulching and parkland clearing.

SLASHING: Involves the mowing of grasses using either a tractor or compact track loader with a slasher attachment.

MULCHING: Where machinery is used to cut and grind vegetation into chips, which is then left as a ground covering to delay weed growth.

PARKLAND CLEARING: A combination of slashing and mulching. The understorey is treated while the tree canopy remains.



  • Treatments break up the fuel continuity, both vertically and horizontally, which slows down the spread of a bushfire and makes it easier to control a fire if it did start.
  • Creates a buffer between vegetation and assets.
  • Improves access and safety for fight fighters in the case of a bushfire.
  • Does not create any smoke.
  • Treatments can be carried out when weather inhibits planned burning.
  • Treatments are not as resource heavy as planned burning.


  • Limited by steep slopes and wet weather.
  • Noisy machines may impact locals.
  • Traffic management required along road reserves.
  • Can be costly
  • Machines can be difficult to source.
  • Machinery has the potential to spread dieback and weeds.
  • Where machines have disturbed the soil, it may be susceptible to erosion.
  • Sites that have been mulched or cleared may be unsightly following works.
