NWP40120 is the nationally recognised Certificate IV in Water Industry Operations. It prepares you for work as a waste water or water plant operator. It has been the current version on the national register since 2021, when it replaced NWP40515 and NWP40615. Employers posted about 401 waste water or water plant operator jobs in June 2026, up 18.4% on a year earlier.
The signals behind this qualification are mixed, and both sides are worth weighing. Specifically: employment in its occupations is projected to grow through 2035, national enrolments are rising and the official shortage list does not rate its occupations in shortage. These are official statistics, not a promise about any individual's result.
Employers are advertising more of these roles than a year ago. Across Waste Water Or Water Plant Operator, about 401 jobs were advertised online in June 2026 (up 18.4% on a year earlier). Roughly 4,619 openings were advertised over the last 12 months, while 220 people enrolled in the qualification nationally in 2024. Enrolment counts people in training, not completions, so the two figures describe the pipeline and the market, not a job guarantee.
None of the occupations this qualification leads to is rated as in shortage on the official list. In the 2025 Occupation Shortage List assessment, Boiler or Engine Operator, Bulk Materials Handling Plant Operator, Cement Production Plant Operator, Concrete Batching Plant Operator, Concrete Pump Operator, Paper and Pulp Mill Operator, Railway Signal Operator, Train Controller, Waste Water or Water Plant Operator, Weighbridge Operator and Stationary Plant Operators nec are rated not in shortage.
Employment in these occupations is projected to grow. Government projections put them at 25,500 workers in May 2025, 26,200 by May 2030 (up 3%) and 27,200 by May 2035 (up 6.9%).
More people are choosing this qualification each year. National enrolments rose from 115 in 2023, to 220 in 2024 (up 91.3%).
The register and the national framework set some of this. Providers set the rest.
State funding for NWP40120 is being verified against official program lists.
Eligibility and student contributions vary by program and provider. The official state listing is the source of truth. In a subsidised place the government pays most of the tuition and you pay a co-contribution set by the program and provider.
