Jurisdictional change to safety regulation authority in coastal waters

The responsibility for administering safety regulation in coastal waters – under the Petroleum (Submerged Lands) Act 1982 and attendant regulations – reverted to the department on 1 January 2012. This service had previously been provided by the National Offshore Petroleum Safety Authority (NOPSA).

Safety documentation previously accepted by NOPSA remains accepted and in force until such time there is a legislative requirement for review.

The department’s Resources Safety Division has responsibility for the day-to-day administration of the occupational safety and health laws contained in the submerged lands legislation. This applies to:

  • all State coastal waters from the mean low water mark (MLWM) on the mainland to the 3 nautical mile limit
  • all offshore petroleum and diving operations, including vessels engaged in such activities.
