Membership is open to students and others through the formation and registration of chapters in schools, colleges, universities and community groups that sign on to the Charter of the Benenson Society. Individual membership may be held by teachers and others interested in supporting the work, as well as by members who finish their studies and wish to remain associated with the Society.

The Society has no fees, budget, income or office. It has drawn on IT support from St Aloysius’ College in Sydney and Xavier College in Melbourne, and the website has been supported by the Office of Justice and Peace of the Archdiocese of Melbourne. It has, however, no official connection with any organization, and the Charter is the only definition of membership.

The Society has a rather loose structure and organization so that it is best suited to the needs and opportunities in each school, college or university, in which there is a chapter. A chapter may use the name Benenson Society, and the symbol of the white rose, simply by signing on to the Charter and registering the chapter on our website.
It is hoped that chapters would assist each other through group email lists and other forms of communication. Joint action on various cases could be thus promoted and resources shared. The Society seeks to cooperate on specific issues with Amnesty International (while not having any formal membership or link with the organisation). It also seeks to work with other organizations, such as Consistent Life, a network of over 200 organizations that oppose war, abortion, the death penalty, euthanasia and poverty, Christians Against Torture, founded by Peter Benenson, Aid to the Church in Need and Christian Solidarity Worldwide, both of which advocate for those imprisoned or persecuted because of their religious beliefs, Human Rights First, and other human rights organisations.
The first Patron of the Society was the late Bishop Michael Evans of East Anglia.  Bishop Michael was a member of Amnesty International from 1976. In the 1980s, he was a member of the then British Section Council for two years, coordinated a local Amnesty campaign for the release of a Soviet prisoner of conscience, and chaired the Section’s Religious Bodies Liaison Panel for many years. He also wrote the Amnesty prayer for their ‘Protect the Human’ campaign.
