Yes, has been very cold this year in Adelaide. We had a fire in the hills with a few houses lost lit by a fire bug :N: , where I live though the fields still have a green tinge but I am sure next year will be bad again. I have removed all the gumtrees near my buildings and keep a a good 40 meters of green grass around the house but fortunately for me I have the water and space to do so. People have got to get there heads out of there arse when they consider having a native garden all around the house. I like my natives but keep in mind they love to burn. Also woodchip can be hard to put out. My friends drought proof native mulched garden almost cost him his house. Shade cloth on the eaves can also be problematic.
