Gas Regulations, Standards and Licensing Obligations
The regulatory framework
Gasfitting in NSW sits inside a layered framework. The Gas Supply Act and its regulation set the broad legal duties, Standards Australia publications (notably AS/NZS 5601 Parts 1 and 2) provide the technical rules, and the state licensing body administers individual and business authorisations. Candidates must know the difference between a legal obligation (a duty imposed by Act or regulation) and a compliance standard (a deemed-to-satisfy technical reference). A common trap is assuming that because a standard is not itself legislation, it can be ignored; in practice it is the benchmark against which work is judged.
Licensing and scope of work
Understand the classes of work authorisation, the requirement to hold a current licence for the type of gas and class of work performed, and the obligation to work only within the scope of that licence. Supervised work, notification of completion, and certificates of compliance are recurring exam themes. Another trap: assuming a licence covers all gas types and all appliance classes. It does not, and questions often hinge on whether a particular task falls inside or outside the holder's scope.
Documentation and records
Regulations require records, compliance certificates, and retention of documentation. Know who must be given a certificate, when, and for how long records are kept. Questions frequently test whether the certificate must be issued before or after commissioning, and whether the customer or the network operator receives it.
Worked rule of thumb
Before starting any job, run a three-part check: (1) Is the work within my licence class and gas type? (2) Does it require notification or approval before work begins? (3) What certificate and records must I leave behind? If any answer is uncertain, the correct exam answer is almost always the more conservative, documented path.
