Governing documents


The ASO has a number of trustees, elected from the membership, and which run for a term of three years. The trustees are led by a Chair, who is supported by the board of trustees with designated roles.

Trustees can stand for two terms, except in the situation where a Trustee takes up the role of Chair or Treasurer in which case up to three terms are permitted.

Trustees sit on the ASO Committee, which forms the main decision making body of the ASO. The Trustees may be supported on the Committee by other co-opted roles as required by ASO activities. These additional co-opted roles are not ASO Trustees.
