Employers are posting fewer swimming coach or instructor jobs than a year ago. About 891 swimming coach or instructor jobs were advertised online in June 2026, down 7.1% on a year earlier. Over the last 12 months there were about 11,600 job ads, while 43,900 people were training in the qualification nationally (2025). Ads show the market. Enrolments show the pipeline. Neither is a job promise.

Certificate III in Fitness graduates find work at the typical Certificate III rate, but earn less soon after training. In the 2025 NCVER Student Outcomes survey, 89.5% were employed or in further study after training. The typical Certificate III result is 88%, across 105 qualifications. Median income after training was $42,300, against $54,000 typical. 83.6% were satisfied with the training, against 90.6% typical. Income here is the survey median about six months after training. It includes part-time work, so it is not the full-time award rate.
Enrolments in the Certificate III in Fitness are steady. Across Australia, 42,035 people enrolled in 2024. In 2025 it was 43,900, up 4.4% in a year. National data for SIS30321 starts in 2021.

Browse coursesGet Course maps SIS30321 to its occupations using the register’s own outcome wording, shown with ANZSCO codes (here, 4523) so the mapping can be checked. Job advertisement counts come from the Jobs and Skills Australia Internet Vacancy Index and count online ads, not vacancies filled. Enrolment counts come from NCVER Total VET Activity and count people in training, not completions. Outcome benchmarks marked “typical” are medians computed by Get Course across all Certificate IIIs in the same NCVER collection; they are derived figures, not official NCVER benchmarks. Funding rows appear only after verification against the official state program list.
