They don't.

A "porky" is a lie. If someone has told you that Australians call echidnas porkies, they are telling you a porky.

Some people may call them porkies for two reasons - porkie is short for porcupine and, even though echidnas are not related to porcupines, they have sharp spines like porcupines do. Also, the word porcupine rhymes with spine (the sharp quills on an echidna) and Australians are fond of rhyming slang.
