Overeaters Anonymous – Melbourne Intergroup – Events Group / Intergroup / Region / World Service Office (WSO)

A group consists of two or more people. Each group practices the Twelve Steps and Twelve Traditions of OA. No member of a group is required to practice any actions to remain an OA member or to have a voice at a meeting.

No group events currently listed.


Two or more groups can form an intergroup (IG). The intergroup provides services to existing groups within its geographical area and spreads the OA message of recovery to those who still suffer. Melbourne Intergroup meets on the first Saturday of the month (except January) from 8.00am to 10.00am at the OA Office, 70 Punt Road, Windsor

March 2020 Share-a-thon

CANCELLED – The Share-a-thon which was to be held on March 22, 2020 at the Windsor office has been cancelled. This is in light of COVID-19, to do what we can to slow the spread. If you’d like to read the World Service Office’s statement on groups making individual decisions about what to do at this time, click here.

Keep your eye on this page for information on the next Share-a-thon! The Share-a-thon is a great way to meet other members, find a sponsor and get recovery.

Bi-Annual General Meeting – March 22, 2020.

The Bi-Annual General Meeting was originally going to be a part of the Share-a-thon but as it had been cancelled, the general meeting went ahead on that day virtually (online) via ZOOM. The online meeting was a success and was encouraging to know that OA can still thrive and move forward in this challenging time.

Check back later for details of 2020 Convention


OA has 10 regions worldwide that maintain direct communication with groups and intergroups. Regions sponsor local conventions and assemblies. Regional assemblies also nominate trustee candidates to serve on OA’s Board of Trustees (BOT), whose members are elected at the World Service Business Conference (WSBC).

World Service Business Conference (WSBC)

The WSBC, attended by delegates from around the world, meets annually each May to conduct the business of OA and to elect the 16-member Board of Trustees. The board acts on behalf of all members of the OA Fellowship. The World Service Office (WSO) works with the BOT to provide quality support and services to the entire OA Fellowship.

I.D.E.A. – International Day Experiencing Abstinence

Since 1992, on the third Saturday in November, members of Overeaters Anonymous worldwide observe an International Day of Experiencing Abstinence (IDEA).

This day recognises the strength of the Fellowship worldwide. On the last Saturday in February, at 11:30 a.m. OA members pause to reaffirm the strength inherent in OA’s unity.


On the 12th December to encourage OA service boards, meetings and individual members to reach out to those within the Fellowship who are still suffering from eating behaviours.


Celebrated on the third Saturday of January each year.
