How do I find out who's my member of parliament?

Easy!

You can find out which electorate you are in from the State Electoral Office website: http://www.seo.nsw.gov.au or call the Australian Electoral Commission on 12 23 26. Then go to the NSW Parliament website to find out who your member of parliament is (formally called a Member of the Legislative Assembly) and how to contact them: http://www.parliament.nsw.gov.au.
