The Alice Springs sample illustrates this point with the majo~ity of households movi~g cars ~o flood ~=ee loca~ions while others suf~ered damage; in G~e case to :h=ee cars at o~e address. The ANU?LOOD prog~am allows for =amage to grounds but does no~ include vehicles. Th~s is because areas with flood ~xperie~ce and an adequate warni~g rarely suffer suc~ losses. :abie 2.3 i~dioated wnich ~ouseholds undertoo~ aCtlO~S tQ reduce damage. The ~ajcrity of ~hose with overfloor f:ooding attempted to red~ce damage. This included lif:ing ItemS, especially small electrical appliances, but in many instances also involved efforts to stop the flood waters ~~~ering the proper~y. A~~empts were made using towels or Jcher ~aterials to seal door openings. Such actions are Jnly of value in ~hose cases where the flood exceeded ~he floor level by a ~ew ce~~i~etres. Two of the surveyed househo~ds used sandbags for si~llar purposes.

The general response was :0 attempt to stop wate~ entering tne house, this is only success~ul when overfloor flooding 1S ve~y shallow, although it may allow more time to lift ite~s. Greater emphasis on lifting household items or removing the~ :otally from :he property ~ould be the recomme~ded 9rocedu~e.

Further guida~ce on ~easures to ~educe damage could be included in she warning brochure and incorporated with [cood 'warning messages (see Part 3).
