Entry requirements

Applicants should have completed a year 12 or equivalent level of secondary education. Applicants must be over the age of 18 at the time of commencement. This qualification may be accessed by direct entry.

Licensing & Regulatory Information:

The Victorian Building Authority (VBA) regulates plumbers, plumbing work and plumbing standards.

The Victorian Plumbing Regulations 2018 (the Regulations) define ten main classes of plumbing work and five specialised classes[1].

To lawfully carry out plumbing work in one or more of these classes in Victoria, you must be one of the following:

  • Licensed in the class
  • Registered in the class (or hold provisional registration in the class)
  • Be in training under the supervision of a licensed plumber.

Specialist or restricted classes.

The process is different for specialised and restricted classes of plumbing.

For specialised classes, you will need to hold registration or licence in the relevant parent class. For restricted classes, you must have completed the relevant education pathway or hold equivalent knowledge and skills.

Plumbing practitioners also need to satisfy the Qualifications and Experience Review Committee (QERC) they are competent to carry out work in that class of plumbing. This requires an interview and assessment.


Completion of the general construction induction training program specified by the model Code of Practice for Construction Work is required before entering a construction work site. Achievement of CPCCWHS1001 Prepare to work safely in the construction industry meets this requirement.

This is a licenced occupation. State and territory jurisdictions may have different licensing, legislative, regulatory or certification requirements. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.
