The Australian Information Security Association (AISA) was originally formed in 1999 as the Information Security Interest Group (ISIG). It was incorporated in 2001 and changed its name to the current one in 2005. Branches exist in Sydney, Melbourne, Canberra, Brisbane, Perth and Adelaide. The association has over 1000 paid members. Meetings occur in each state every month and attract approximately forty to fifty attendees from a wide cross-section of organisations.
AISA is an organisation for individuals rather than companies and aims to maintain an unbiased view of information security in Australia.
AISA hosts two conferences annually, a national conference held in Sydney and a further conference in Perth, WA. These conferences are fast growing to be Australia's most popular on the topic of information security. As a major benefit to membership, these conferences offer free admission to AISA members.
