Better safe than sorry but seriously BB has never creeped this late into the year before, at Ch 10 it was always a first half of the year program so that obviously never came into consideration.
Bushfires are becoming more frequent and severe though (climate change, global warming etc...) and you can never be certain from year to year of the potential severity of a bushfire around any given area like the BB compound that has a lot of dry vegetation to burn.
You can flippantly dismiss it out of hand all you want but the severity of a bushfire could be on the extreme end of the scale that the BB compound can't be saved, what then?
