ACT residents are the most concerned in the country about being impacted by bushfires this season, yet they are the least likely to have taken steps to prepare, according to the latest NRMA Insurance claims data.

While 74 per cent of ACT residents are concerned about being affected by bushfires or grassfires this spring and summer, 32 per cent said they would know what to do if a bushfire threatened their home and only 20 per cent had taken steps to prepare and protect their homes over the past six months.
