It's not a bad map but looking at the mud line on some rooves, it wasn't shot at the hight of the flood and if you follow the river to the mouth you can see what colour it's supposed to be. I found if you click on the terrain button you'll see what images were overlayed. A lot of the map is dated September. I guess they had to shoot between the clouds as well. Even they are imaging through sucker holes
I believe the mayor is pushing for an enquiry but the premier is sidestepping that issue at the moment.
[Edit]
Looks like they have added data from the 14th. Change the date at the top on the map when zoomed out.
