The Ditmar Award is Australia's oldest science fiction, fantasy and horror award, presented annually since 1969, usually at the Australian "Natcon". The historical nominations and results (listed in boldface) of the Award follow.

(The programme book for the 1990 Natcon, Danse Macabre, records that no Ditmar Awards were presented in 1974.)

(The Australian newszine Thyme records that Tschaicon was the "First Australasian Science Fiction Convention", the relevant constitution having had "Australian" replaced with "Australasian" throughout; that the award categories used "Australasian" rather than "Australian"; and that the constitution was modified, at Tschaicon, to have "Australasian" changed back to "Australian".)

There was an award from the committee, in the form of a miniature Ditmar Award, to Marc Ortlieb for Best Toastmastering.

There were insufficient nominations for the William Atheling Jr Award.

The awards ceremony included presentation of the A. Bertram Chandler Award to Lee Harding, and another three special awards to Damien Broderick, for Transmitters; John Foyster, for past work in fandom; and the Nova Mob, for going on for a long time.(The A. Bertram Chandler Award is a separate award.)

The awards ceremony included presentation of five special awards from the Syncon committee to Jack R. Herman, Eric B. Lindsay, Ron Clarke, Sue Clarke, and Shayne McCormack.

An awards ceremony was held 16 December 2000; the actual trophies were presented later at Swancon 2001.
