UP THE BLUES,
You don't have porcupines in Australia.
You have echidnas.
Completely different species.
Porcupines are rodents, echidnas are monotremes.
Otherwise known as spiny anteaters.
If you are an Australian, you need to find out more about your own fauna.
I grew up there, but I shouldn't know more about it than you.
