Bushfire Bunkers/Shelters
Here is a link to a really comprehensive article written, and generously shared, by a man called Ian Pullar, about the issues relating to bunkers and the pros and cons of certain features etc and what to look out for. It seems really comprehensive and well thought through. It would be very useful for anyone looking to buy or build a bunker to read so they are informed of issues before they start.
The link is: Bushfire Bunkers by Ian Pullar
The other thing I have come across is a community information sheet by the Building Commission of Victoria which also outlines the issues to consider before embarking on a bunker. The link for that one is: Bushfire Bunkers Community Information Sheet
