Prior to 2012, each State and Territory was responsible for petroleum licensing and regulation in their respective offshore waters. However, following the amendment of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 to implement recommendations from the Productivity Commission, responsibility for the licensing and regulation of petroleum-related activities occurring greater than 3 nautical miles from shore (or, technically, from the territorial sea baseline) passed from the various States and Territories to the Commonwealth Government. The National Offshore Petroleum Titles Administrator (NOPTA) was created to have responsibility for the day-to-day administration of petroleum & greenhouse gas titles in Commonwealth waters, with Geoscience Australia managing the well and seismic database (NOPIMS) for these areas on their behalf.
