IPAWS is a spatially enabled decision-support and data management tool developed by ThinkSpatial for Victoria's Catchment Management Authorities. IPAWS assists referral authorities in the management of Planning Application Referrals, including the initial application submission, automatic timeframe notifications, generation of response documents, and the management of VCAT hearings and certification requests.

A key factor in the success of IPAWS is its “map-driven” interface; administrators are able to view and interact with outstanding and completed referrals in a Geographic Information System (GIS) such as ArcGIS or MapInfo. The GIS interface allows administrators to easily identify the relevant planning overlays, planning zones, and to factor any nearby applications into their decision-making.
