Legislation & compliance

The Australian government has responsibility for Australia’s offshore areas beyond three nautical miles from the territorial sea baseline.

The Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA) and associated regulations provides the legal framework for the exploration and recovery of petroleum and for injection and storage of the greenhouse gas substances in offshore areas.

The OPGGSA establishes: the Offshore Petroleum Joint Authorities (the Joint Authorities) for each offshore area; NOPTA; and the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).
