Why there is no single answer
"What does a plumber earn?" sounds simple, but the question bundles together very different people: a first-year apprentice, an employed tradesperson on a regular roster, a self-employed specialist, and the owner of a business with staff and vehicles. Their incomes, hours and risks have little in common. Any one figure you see online is a blend of those groups, and usually a blend nobody explains.
What moves the number
- Career stage. Apprentices are paid as learners and progress as they gain competency and experience. After qualifying, a tradesperson may move into a leading hand, supervisor or estimator role.
- Employment type. An employee has set pay arrangements, leave entitlements and the employer carries the costs of running the business. A contractor sets their own rates, but covers tools, vehicle, insurance, tax and slow weeks.
- Specialisation. Plumbing is several fields: general maintenance, drainage, gas fitting, roofing and stormwater, and larger hydraulic and commercial work. Demand and responsibility differ between them.
- Hours and conditions. Overtime, weekend work, being on call and working in difficult conditions can all change what ends up in the pay packet.
- Location and demand. Pay can vary with where the work is and how busy the market is at the time.
Employee or business owner
It is tempting to compare the hourly rate on an invoice with an employee's hourly pay and conclude that a plumber in business must be earning several times as much. That comparison leaves out nearly everything. An invoice has to cover vehicle, tools and materials handling, insurance, licensing and training costs, administration, tax, unproductive travel time, jobs that go wrong and periods without work. What remains is the owner's income, and in a quiet month it can be small.
Be careful with headline figures
Salary websites, job boards and news articles are handy for a rough feel but weak as evidence. Ask a few questions before you trust a figure.
- Is it an average or a median? An average can be pulled up by a few very high earners.
- Does it describe employees, contractors or business owners?
- Does it include overtime, superannuation and allowances, or only base pay?
- How recent is it, and how many people does it represent?
Where to check current information
For pay rates and employee entitlements, the Fair Work Ombudsman publishes pay guides and an online pay calculator that reflect the modern awards and agreements in force. For the labour market, skills demand and occupation outlooks, see Jobs and Skills Australia. The Australian Bureau of Statistics also publishes labour force and earnings data. Use those sources directly, because the figures change and a blog post can fall out of date.
Why a customer might care
If you are hiring a plumber, the hourly figure on a quote is not the plumber's wage. It carries the cost of running a licensed trade business safely, which is part of why prices differ between providers.
