The Planning Institute (PIA) is the only national organisation representing qualified urban and regional planners and other related disciplines in Australia. Originally known as the Regional and Town Planning Institute, it later became the Royal Australian Planning Institute, until 2002 when the current name was adopted. PIA represents around 5000 members nationally and internationally. It is governed by a National Board of Directors and managed by a professional administration. It is a member-based organisation with its management complemented by volunteers, who support and contribute to its activities on various levels. PIA runs a number of events at both the National and State/Territory levels. PIA also publishes Australian Planner, Australia's leading peer-reviewed journal for the planning profession, and the most read and influential planning journal in Australia and the Pacific Region.
