Established by the Victorian government, AUSEN currently has 44 Australian member companies, representing a broad spectrum of oil and gas industry specialists. In it's interactive environment, AUSEN members can openly discuss current and potential project activity, and trends in the oil and gas sector.

AUSEN membership often affords business opportunities that can be unseen and unreachable as an individual enterprise, with the group nurturing a close relationship with key government departments and initiatives, in particular the state governments’ Industry Capability Networks(ICN) - a first-port-of-call for purchasers, specifiers and procurers of equipment and services. Through the group's ties with government industry departments, AUSEN members are able to obtain assistance with R&D funding, achieve representation with overseas trade delegations, and secure government backing to participate in international exhibitions.

In addition, AUSEN has an associate membership of mechanical contractors and consultants, enabling members to broaden their contacts and enhance their knowledge of all aspects of oil and gas and other energy industries. Details of these associates, and others in their field, are listed on AUSEN’s extensive database, which is available to all new members upon signup.

AUSEN's quarterly meetings are both lively and educational, with discussion to leading successful business strategies, advice on pitfalls, and the building of formal and informal alliances. Although some members are in competition, the group recognises the advantage to be gained from a group identity, and wanting to avoid more contracts being awarded to offshore bidders.”
