We haven't got all of Australia covered yet! If there isn't a Joomla User Group close by, consider starting one. There are plenty of resources available on the Joomla Community Portal, or jump into the Joomla Australia Forum and let us know what you'd like to do.
All you need is a venue and a handful of enthusiastic Joomla! Users. Other active Joomla! community members will help you organise your first Joomla! Meetup.
