I’ve never heard of black squirrels either, but I grew up hunting grey squirrels and still do. Incidentally, from pictures I’ve seen and from nature shows on TV, what they call a possum in New Zealand is not the same animal we call a possum over here. I assume the possum in Australia is the same critter found in New Zealand.
New Zealand possums were introduced by Europeans from Australia, and have become a pest over there. The bad side is that these possums in New Zealand eat the native birds eggs. The good side, if you see it that way, is that hunting and trapping possums for their fur has given some residents an alternative income.
