MAR50120 is the nationally recognised Diploma of Marine Engineering. It prepares you for work as a ship's engineer. It has been the current version on the national register since 2020, when it replaced MAR50115 and MAR50613. Employers posted about 49 ship's engineer jobs in June 2026, down 4.6% on a year earlier.
The independent signals behind the Diploma of Marine Engineering line up. Ship's engineers are in national shortage, employment is projected to grow through 2035 and enrolments are rising. These are official statistics, not a promise about your result.
Job ads for ship's engineers are holding steady. About 49 ship's engineer jobs were advertised online in June 2026, down 4.6% on a year earlier. Over the last 12 months there were about 800 job ads, while 80 people were training in the qualification nationally (2025). Ads show the market. Enrolments show the pipeline. Neither is a job promise.
Australia's official shortage list rates master fishers, ship's engineers, ship's masters and ship's officers as in shortage.
