CES Australia


Welcome to the Australian Community Exchange System!

The Community Exchange Network is the first and only global network of communities using alternative exchange systems.

Currently there are three CES servers hosting the different communities. This is the Australian server and there is also a Global server hosting trading communities from around the world, and Timebanking Australia.

What is the CES?

The Community Exchange System (CES) is a community-based exchange system that provides the means for its users to exchange their goods and services, both locally and remotely.

It could also be described as a global complementary trading network that operates without money as it is commonly understood.

Global CES Network

The Community Exchange System is a network of around 700 exchange groups around the world. Go to the global CES website to see the full list.

Community Exchange System (CES), a free software service that helps communities manage and exchange resources, is to be migrated to Drupal in 2014. The network currently consists of 700 more or less active communities in 62 countries and the software has so far been translated into 22 languages. Most of the software will be published open source, as a Drupal 8 distribution called eserai, and several customised deployments are already planned.

In the medium term, more resources will be sought to bring together these deployments into one decentralised network, and to build a free, open source phone application suitable for recording and mobilising community activities.

Communities wanting to be part of a global, decentralised exchange network can create accounts on this website. Drupal engineers wishing to support this long-term effort should contact Please watch this space for a coming crowdfunding campaign.
