SASS has a Membership drawn from across the Christian denominations mainly in Sydney but also throughout NSW. Formed when a small group of Anglican Stamp Collectors met in December 1972, the society has steadily grown, drawing members from many denominations and continues to meet six times annually.

With a very stable membership of 50 in 2006, and the average meeting attendance's of about 32, the members have developed close friendships and enjoy each others company on each meeting day and as they call on each other between meetings.

Membership is open to Stamp Collectors who are members of a Christian Church. Membership is applied for by filling in the application form available at meetings. Financial membership entitles a member to receive 6 copies of "Nu-Issue" - the SASS Newsletter, and to have a say and vote in the annual elections. Annual subscription is $10.00.

SASS is "managed" by a committee consisting of President, two Vice Presidents, Treasurer and Secretary. Each of these positions being elected annually.

From its inception the society has had the support for Missions and Missionaries as one of its prime objectives. The society directly supports the Church Missionary Society by maintaining stockbooks, sorting vast quantities of donated stamps, and assisting in the sale of these stamps. Many thousands of dollars have been raised for this mission society alone over the 30 years by the enjoyable work by the membership.

SASS is affiliated with PHILAS the Philatelic Association of NSW
