Combinatorial Mathematics Society of Australasia

The Combinatorial Mathematics Society of Australasia (CMSA) is a professional society of mathematicians working in the field of combinatorics. It is the primary combinatorics society for Australasia, consisting of Australia, New Zealand and neighbouring countries. The CMSA existed as an informal group from 1972 until formal establishment in 1978. It became an incorporated association in 1996, and as of 2017, it has over 280 members including 110 life members.

Membership and management
The membership of the CMSA consists of four classes: ordinary members, honorary members, institutional members, and life members.

The CMSA Council is responsible for all activities of the Society. It consists of a president, vice-president, immediate past president (if there is one), secretary, treasurer, and a number of other members elected by members of the CMSA at its Annual General Meeting.

Activities
The main activities of the CMSA are to publish the Australasian Journal of Combinatorics (AJC), and to oversee the organisation of the annual Australasian Conference on Combinatorial Mathematics and Combinatorial Computing (ACCMCC), and the ten-yearly International Combinatorics Conference (ICC). The CMSA also publishes an E-Newsletter in April, July, and October each year.

Student support
The CMSA strongly encourages student participation in its conferences. The CMSA Student Support Scheme provides travel support, and the CMSA Anne Penfold Street Student Prize (formerly called the CMSA Student Prize, 2001–16) is awarded annually for the best student talk.

CMSA Medal
The CMSA Medal is awarded at most every three years, to honour a member of the CMSA who has made outstanding and sustained contributions to combinatorics and to the Australasian combinatorics community.
