Heh heh - I haven't looked at your link, but yes, bull sharks have been sighted inland from where they should be!
Mind you, they didn't seem to report too much about crocs in Rockhampton - I mean, up there, they are pretty endemic even when it's not flooded, so I'm surprised they didn't turn up in the main street - or if they did, that no one mentioned it.
It's a bit strange now - there's more flooding going on in other areas of Australia but you can feel the lack of interest from the news teams - Brisbane was the "crisis of crises" and nothing else is quite matching up to it, so they're going "oh yeah, and X,Y and Z in NSW and Victoria have also been flooded". (well not quite, but you get my drift). No one has died in any of the other areas (thank God) so that's probably one of the reasons - but it's also trauma-weariness, I think. Some western parts of NSW are going to cop the heaviest rainfall in over 100 years - probably also causing flash floods - and it's barely getting a mention.
The next problem is going to be the amount of sick people - because of the humidity and general temp in Q'land, the mould will start quite quickly. One friend of a friend who lives in Rockhampton (they copped it a week or so before Brisbane) says it's already started on her stuff; and the big problem is that they're not going to reconnect people's electricity until their houses have been safety checked - so no fans, no air con, no heaters to dry the place out - perfect mould-growing conditions, and the spores will --> asthma attacks, chest infections etc. Plus the issues with contaminated water - people are running the risk of septicaemia if they have open wounds on any part of them in contact with the water/mud; and they need to boil their water in some places because of E.coli contamination from sewage.
It's bloody awful. If I thought I could really achieve anything by going up there, I would - but I can't, in all honesty, and I have DS who is only 3 so it's a bit unreasonable to abandon him. So :( though.
