Recently I visited Warrandyte in Melbourne, Vic Australia. Last summer there were very bad bush fires with many deaths and homes destroyed in Victoria. We have been advised to get our fire action plans ready. This family has built a fire bunker. The concrete blocks form a square tunnel to a door to a room that is under the hill that is covered in large boulders. The room has storage, lights and an air system. The family don't anticipate using this except for in an extreme emergency when they are caught as they intend to leave the area before the fire hits. The recent fires have been merciless having no rhyme or reason as to what burnt and what was left. Be prepared!
