In the table above, see the Glossary distinctions between Seats won by ticket and Seats won by party, and between Seats won by party and Seats held by party.

Family First: The Family First party was founded in 2002 in South Australia and has policies which support traditional family values. It ran candidates in all states at the 2004 federal election and was successful in winning a Senate seat in Victoria (Steve Fielding).

Pauline Hanson's One Nation Party and One Nation: This party, which had endorsed candidates at the previous (2001) Senate election under the name 'Pauline Hanson's One Nation Party', was reorganized and changed its name in some states to 'One Nation'. The original party name has been maintained in this database to permit easy comparison over time and between states.
