Founded in 1970, the Association of Applied Geochemists is an international organisation specialising in the field of applied geochemistry whose purpose is to:

• Advance the science of geochemistry as it relates to exploration and the environment
• Facilitate the acquisition and distribution of scientific knowledge, including publication of GEEA and Explore
• Encourage research and development in applied geochemistry
• Sponsor symposia, seminars and technical meetings
• Support students in applied geochemistry

The Australian Geoscience Information Association (AGIA) Incorporated is a national group of persons and organisations working in any area of geosciences at the professional level, and acts as a medium of communication for all those interested in geoscience information.
The objects of the Association are:

• to initiate, aid, promote and improve the exchange of information in the earth sciences and related areas;
• to encourage mutual co-operation among users and processors of earth sciences and resources information; and
• to maintain links between members and geoscience information organisations in Australia and overseas.

AIG is the leading professional institute representing geoscientists in all professional sectors throughout Australia.

AIG was formed in 1981 to help:

• provide effective representation on issues affecting the status and perception of geoscience professions
• cooperate with other professional institutes on matters of common interest
• ensure the availability of diverse, educational opportunities for students at all levels
• develop and maintain standards for professional practice
• provide high quality, accessible, relevant short courses, seminars and conferences
• promote continued professional development by members
• help to enhance employment opportunities for geoscience professionals.

The International Association of Hydrogeologists is a professional association for those within disciplines related to groundwater, its occurrence, utilization, testing and management. IAH is a scientific and educational organisation that is truly international, and was established to foster closer ties, cooperation and information exchange related to the study of groundwater. IAH is non-government and non-profit and has over 3500 members internationally from around 135 countries. The Association is affiliated with the International Union of Geological Sciences (IUGS), and was founded during the 20th International Geological Congress in 1956.

By its statutes, the IAH is an association of individuals and corporate members, and not a federation of national committees. National groups do, however, organise local meetings and other activities. A proportion of the national membership subscriptions goes to the local organisation to support these activities, the remainder to the international body. The country of the international secretariat is changed every several years.

The IAH publishes the Hydrogeology Journal quarterly and various workshop and conference proceedings.

The Australian Society of Exploration Geophysicists (ASEG) is a learned society of approximately 1,200 members, embracing professional earth scientists specialising in the practical application of the principles of physics and mathematics to solve problems in a broad range of geological situations.

Publications include an internationally recognised scientific journal "Exploration Geophysics"  and a stimulating news magazine "Preview".

Members of the ASEG are employed in exploration for oil and gas; exploration for base metals, precious metals and diamonds; environmental assessment, environmental monitoring and remediation; geotechnical investigations, groundwater monitoring and hydrogeology, secondary and tertiary teaching, public sector research and academia.

Australia is currently at the leading edge of new technologies in exploration and environmental geophysics as a consequence of the extensive cover of young sediments across our vast flat land. Consequently our members find their skills in demand throughout the world, and international travel is a characteristic of our profession.

Key strategies are to:

	cater for a wide diversity of members.
	influence the decision making processes of government, particularly to support geoscience research and teaching.
	encourage and promote wider community awareness and application of Earth sciences.
	provide media and forums for communication in the Earth sciences.

The Society 's members represent all Earth science professions, including geologists, geophysicists, geochemists, palaeontologists, geotechnical and engineering geologists, environmental geologists, and associated professions. Members come from the minerals and petroleum industries, government departments, research and education institutions and consultancy groups.

The GSA is managed by a National Executive, with an administration office in Sydney. Standing Committees provide an important focus for national issues.

Geoscience Australia is a world leader in providing first class geoscientific information and knowledge which enables government and community to make informed decisions about:

• the exploitation of resources
• the management of the environment
• the safety of critical infrastructure and
• the resultant wellbeing of all Australians.

We look at key issues such as the global attractiveness of Australia's offshore and onshore exploration, improved resource management and environmental protection. We play a key role in developing a sustainable energy supply for Australia's future.

The outcome of our work is an enhanced potential for the Australian community to obtain economic, social and environmental benefits through the application of first class research and information.

Our activities cover onshore, offshore and spatial information.

• Onshore activities focus on enhancing mineral exploration and environmental land-use planning. We do this by producing geoscience maps, databases and information systems and by conducting regional geological and mineral systems research. Our activities also contribute to safer communities and critical infrastructure and the maintenance of fundamental gravity, geomagnetic and seismic networks.
• Offshore activities focus on providing pre-competitive data and information to assist in identifying new prospective basins for petroleum exploration, and the geological storage of carbon dioxide, in Australia's offshore jurisdiction. Activities also include mapping and documentation of Australia's maritime boundaries, studies of the marine environment using seabed mapping techniques and determining estuarine water quality and health. These studies assist natural resource management.
• Spatial information activities focus on providing key spatial information of Australia with an emphasis on response to rapid and slow onset hazards, the detection of change, emergency management requirements, natural risk assessment and marine zone management. Activities also include coordinating the implementation of the Australian Government's policy on spatial data access and pricing.

The Petroleum Exploration Society of Australia is a non-profit association of individuals involved in the exploration of oil and gas. The purpose and objectives of PESA are:

• To promote professional and technical aspects of the upstream petroleum industry throughout Australia by providing a medium for gathering individuals interested in oil and gas exploration
• To present views and discuss technical and professional matters relating to the upstream petroleum industry
• To foster and provide continuing education for the benefit of members; and
• Maintain a high standard of professional conduct on the part of its members

The Young Earth Scientists (YES) network is composed primarily of scientists under 35 years of age, and was formed as a direct result of the IYPE.  The Y.E.S. network, in close collaboration with IYPE Corporation, set up an international committee to organize a World Congress for Young Earth-Scientists to discuss the main topics of the IYPE: health, climate, groundwater, ocean, soils, deep Earth, megacities, hazards, resources, and life.  Young representatives from geological associations and institutions, young leaders in politics, and delegates from administrative bodies will meet at the congress to establish a worldwide network between future leaders and policy makers and future earth science advisors.
