The signals behind the Diploma of Well Servicing Operations are mixed, and both sides are worth weighing. Drillers are in national shortage, employment is projected to grow through 2035 and job ads in June 2026 were up 22% on a year earlier. Enrolments are falling. These are official statistics, not a promise about your result.
