Employment Opportunities for a Plumber

The industry is dominated by small firms and self-employed tradespeople. Plumbers may also work for federal or state and territory government departments concerned with public works. Plumbers are involved in everything from domestic maintenance to high-rise construction.Competition is strong for available apprenticeship positions. With further training and experience, plumbers can become technical and sales representatives, building supervisors, building and construction managers, plumbing inspectors, hydraulics consultants, technical teachers, estimators, building contract administrators or purchasing officers, or start their own business.Demand is linked with activity in the construction industry. However, unlike in other building trades, downturns in building activity have less effect on plumbers because of the work available in renovation and maintenance. Demand is also more stable because, by law, certain jobs must be performed by plumbers.
