In addition to its industrial relations role, AAO works to promote the welfare and enhance the interests of its members and the industry at large by:

  • The collection and distribution of useful and reliable information.
  • Endeavouring to establish uniform trade practices.
  • Promoting and maintaining improved methods of business.
  • Attempting to improve the knowledge, skill and proficiency of members and their employees.
