COVID-19 Updates for resources sector: fee relief | To report a serious incident to DEM, as required by Section 85(2) of the Petroleum and Geothermal Energy Act 2000, licensees should contact the serious incident reporting hotline on: (08) 8463 6666. For more information please visit the Compliance and Monitoring webpage | DEM-ERD has just released the first “Basin in a Box” data-package covering the Simpson and Pedirka Basins. The dataset is available via the “Data and Publications” page. Each package is a consolidated set of seismic and well data to facilitate new ventures and exploration assessments of frontier basins in South Australia. Data releases for other frontier basins will follow. | Changes to data submission requirements during COVID-19 restrictions. For further information see here.

Important Note on the Regulatory Regime for Offshore Waters

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.
