The Australian National Science Fiction Convention or Natcon is an annual science fiction convention. Each convention is run by a different committee unaffiliated with any national fannish body. Bids for running the Natcon are voted on by attendees at the Natcon two years in advance. These votes are held at a Business Meeting organised by the convention committee, and held at the convention, in practice much of the organisation of the meeting is done by a standing committee selected by the prior meeting.
