AUSTRALIAN/SPANISH DUAL CITIZENSHIP RIGHTS

[chippo]

Hi all, I am australian and married to a spanish citizen.

I would like to know, when I receive my Spanish Citizenship:

1) Does Spain recognise my Australian citizenship?
2) and if I was to return to Australia, would I still be considered Australian and be able to use my Australian passport?

I've looked around but can't seem to find the answers.

thanks
