The Victorian government in Australia has introduced new interim regulations for bunkers in which residents can take refuge when threatened by a bushfire. In order to install a fire bunker, a building permit must be obtained and the bunker must comply with performance requirements such as accessing and exiting the shelter, as well as utilities and the air supply. Residents need to purchase a bushfire bunker or shelter which is accredited, or satisfy a building surveyor that it meets the requirements contained in the regulations.
Under the new interim regulations, the first fire bunker has been accredited by the Victorian government. It is built by the Melbourne-based company Wildfire Safety Bunkers and is designed to be installed underground to shelter up to six people. The company emphasizes that the bunker should be used as a “last resort” and evacuation should be considered first.
The company’s web site has an excellent time-lapse animation showing the installation of the bunker. It is on their home page–click the arrow to begin the animation.

The interim regulations will be in effect until proposed new national regulations are approved later in the year.
