I'm currently living in australia. I wanted to know my mothers maiden, can you help me find it please?

Um... you are kidding, aren't you?

You can't ask her, or your father.. or one of your relatives? I doubt anyone reading this knows her well enough to know.

This was asked under Adoption, so...

Hai, this is a world wide site and few people here are from Australia, much less the local area where you were born. Start by asking your adopted parents what they know, and start going to the place they got you from with any names and dates they can give you. It's a lot of work sometimes. Go online for sites in AU specifically for adoptees looking.
