In issue 2 of The Somerset Gazette, Mervyn Binns proposed formation of a "Melbourne Science Fiction Society" that would engage in serious discussions of science fiction literature, whilst the Melbourne Science Fiction Club remained more of a social club. At the first meeting of the proposed group, at Tony Thomas's flat in August 1970, its proposed name was rejected. At the second meeting, held at John Bangsund's house, "The Nova Mob" was agreed upon as the name for the new group. The third meeting was held at the Degraves Tavern.
The first speaker was Bruce Gillespie, who spoke at the club's second meeting.
When the Nova Mob was revived in the mid-1980s, meetings were held at Jenny Bryce's house in St Kilda.
There have been meetings open to all at conventions, but most meetings nowadays are private functions.
