Flood update
My Mum is quite fine today too. Her house wasn't flooded. She's stuck in her suburb and has no power (so I haven't talked to her much today because she is trying not to run out of credit on her prepaid mobile), which is no fun state of affairs, but is comparatively comfortable.
In the end, she wasn't all that concerned about her "stuff". I asked her if she had things in the car ready to go, and she replied that when you stop and think about it, there just isn't that much that you desperately want to save (though she didn't stand to lose the whole house, structure and all, which would be slightly more inconvenient I imagine, because you would have to find an alternative one).
