Get in contact with operators / supporters of hackspaces possibly interested in running a relay
In yesterdays relays meeting on IRC it was mentioned that the best meetups are at existing hacker cons or network operator conferences.
- #hackerspaces on irc.freenode.org
- mentions of Tor on wiki.hackerspaces.org (this page has a nice map of locations)
(Question was specifically about meetups around Australia's eastcoast, but the topic is probably of interest everywhere)
