Melbourne Humanists Meetup Group
Meet other local Humanists, people who believe in the basic goodness of the human spirit without supernaturalism. Go here to join up - http://www.meetup.com/MelbourneHumanists/
Many humanists are also atheists but you don't have to consider yourself an atheist to be a humanist. If you feel you cannot consort with atheists, this meetup is not for you. 
All members of the group must show tolerance for one another.
The aim of this meetup group is to bring humanists together, interacting with each other, whether it be to debate or discuss hot topics, celebrate an occasion, or just have a chin-wag over your favourite beverage.
