Mass death scene ... Bat carcasses line the street. Richmond Valley Council workers have been attempting to clear the bodies around central parts of Casino but staff have been unable to reach some outlying locations. "Some areas along the riverbank are inaccessible and the stench from the rotting carcasses will be quite unbearable for some time yet," said council manager John Walker. People should avoid the area and not try to help living bats themselves as they could bite and scratch and some carry the lyssavirus. Lyssavirus is similar to rabies. Warning ...

Hundreds of bat babies somehow managed to survive the huge heatwave-induced massacre and about 450 of the pups are now being cared for by WIRES animal rescue staff. There are so many babies that WIRES teams from neighbouring areas have been drafted in to provide back-up.
