linux.conf.au (often abbreviated as lca or LCA) is Australasia's regional Linux and open source conference. It is a roaming conference, held in a different Australian or New Zealand city every year, coordinated by Linux Australia and organised by local volunteers.

The conference is a non-profit event, with any surplus funds being used to seed the following year's conference and to support the Australian Linux and open source communities. The name is the conference's URL, using the uncommon second-level domain .conf.au.

Although several online events were run post-COVID, since 2023 Linux Australia has instead auspiced Everything Open. This is a shorter three-day conference that follows a similar format - but without the additional two days of Miniconfs.

Conference history

In 1999, Linux kernel hacker Rusty Russell organised the Conference of Australian Linux Users in Melbourne. The first conference held under the linux.conf.au name was held two years later in

Sydney. The conference is generally held in a different Australian city each time; although from 2006 onward, New Zealand cities have also been hosts.

|Jan 14 – Jan 16 2022

  • 2006: the first conference to be held outside Australia, recognising the importance of the New Zealand Linux community.
  • 2007: a new feature was an Open Day for non-conference attendees, in which community groups, interest groups and Linux businesses held stands and demonstrations.
  • 2008: the second time the conference was held in Melbourne. 100 OLPC machines were distributed to random attendees to encourage development. The Speakers dinner was held at St Paul's Cathedral Chapter House, and the Penguin Dinner was held in conjunction with Melbourne's Night Market, playing on the title of Eric Raymond's book, The Cathedral and the Bazaar.
  • 2009: during the Penguin Dinner, a substantial sum of money was raised for the Save Tasmanian Devils fund – and a pledge made to replace the Tux Logo with the conference mascot, Tuz, to help raise awareness.
  • 2010: over $33,000 raised for Wellington Lifeflight Helicopter Ambulance service.
  • 2011: the event was almost washed out by the floods that devastated southern Queensland.
  • 2016: preparations almost derailed by a massive storm just before the conference opened.
  • 2020: $24,342 raised and donated to Red Cross for Australian Bush-fire relief
  • 2021: in May 2020 Linux Australia announced that the planned 2021 conference in Canberra was postponed until 2022 due to the COVID-19 pandemic and a lightweight virtual conference would be held in 2021 instead.
