Astrex is a Australian Star Trek fan club formed in Sydney.
The evening began with a history of Astrex, given by the president, Susan Clarke, explaining how the club grew out of the old DUSK (Down Under Space Kooks) of the late 1960s. It had originally been called STAC... It sounded and looked too much like STAG! Astrex was chosen partly as a contraction of Australian Star Trek and partly because the club's symbol (the command insignia) looked like an asterix.
