The then Petroleum (Submerged Lands) Amendment Act 2003 amended the Petroleum (Submerged Lands) Act 1967, creating NOPSEMA and providing that NOPSEMA be funded through industry levies. The equivalent provisions can be found in Part 6.9 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006. The Offshore Petroleum (Safety Levies) Act 2003 imposes the levies and its Regulations prescribe how the levies are worked out and when they are due and payable. The levies include:

• safety investigation levy, to be imposed on the operator of a facility in relation to the investigation, by NOPSEMA, of an accident or dangerous occurrence at that facility, above a set threshold;
• safety case levy, an annual levy to be imposed in relation to a facility; and
• pipeline safety management plan levy, an annual levy to be imposed in relation to the pipeline safety management plan that is in force in relation to a pipeline.

Additional guidance on safety case levies is available below. The levies and remittal flowcharts provide an overview of the decision making for levies and remittals. There is a standard form for notifying NOPSEMA of the number of days a mobile facility is not being operated as a facility in Safety Authority waters.

The Offshore Petroleum (Safety Levies) Regulations were amended on 21 September 2006. These amendments improve the coverage of the levies for operators of mobile facilities and introduce a new basis for calculating the Pipeline Safety Management Plan Levy based on the complexity of the pipeline rather than a 'notional length'.
