Australia's ABC (their BBC) has a fantastic 'contribute' channel which is packed full of photos and video of the bushfires. Much better content showing you what it's like as fire comes over the mountain and of the aftermath than what's to be found on YouTube.
And they're truly shareable! Very impressive, why can't the Beeb do something like this?
This one especially shows you what the wind speed's like.
