Not a blowjob. Not at all. It's like a French kiss, but "down under." The entire point of the word is that it's a euphemism for cunnilingus, not fellatio.
Did you see that they used "Australian kiss" as a word during the "Cunning Linguistics" game on On The Spot?

No I didn't. I DID, however, see that they used "an Australian kiss." It sucks that some idiot submitted THE WRONG DEFINITION under a slightly different name, seeing as how the name of the game is a pun on the word "cunnilingus."

Giving a girl oral sex. Like a French Kiss, but down under.
My girlfriend always keeps herself nicely shaved... probably cause she likes my Australian Kisses.

When you kiss that special lady "down under" and "in the bush", you are giving her an Australian kiss.
Eating her pussy is giving her an "Australian kiss".
