(1) A Hoax Convention

from Fancyclopedia 1 ca. 1944
A surprisingly large convention in Sydney Australia in 1941. It was later confessed to be a hoax, never occurred.

Issue 28 of Mumblings From Munchkinland attributes the hoax to Bert Castellari and reproduces a Special Note from issue 117 of Startling Stories reporting the convention to have been held April 13, 1941, and attended by sixty-seven fans. Fantasy Times relayed "scarcely credible news" of an Australian convention attended by 65 fans, pointed out how amazing this was in view of "Australia's small population, war restrictions and the embryonic state of science fiction fandom there", and then congratulated Australians on their achievement.

(2) The First Australian Natcon

The first Australian Natcon, held in Sydney in 1952, was known as the First Australian Science Fiction Convention, but was also called Sydcon; the second, known as the Second Australian Science Fiction Convention, was also called Sydcon II; the fourth, known as the Fourth Australian Science Fiction Convention, was also called the fourth Sydcon.
