'Roo strikes are very common here, it's one of the reasons I no longer ride after dark and try to be off the road well before dusk. According to the NSW insurance association our area, (Queanbeyan/Canberra region.) has the highest rate of roo strikes in the state. It's entirely believable as the do ads around here are like a charnel house! Every morning there will be two or three new corpses just on the road between Bungendore and Queanbeyan. Some of them are big buggers too! The cost in terms of insurance is frightening.
Next time I see a fresh, big, eastern grey I'll try and stop and take a pic so you can get some idea of the size they can be! It'll have to be a fresh one as they get stinky pretty damned quick when it's 30*C+ and the corpses are just left to rot, I'm told because they are a warning to drivers that they are around! Well 'Duh'!

PS. That one in the vid is tiny, only a joey or very small swamp wallaby.
