Why does this get blurry for a roof plumbing crew?
A roof plumbing business in Australia often runs with a core crew doing everyday guttering, downpipe and flashing work, then brings in extra hands for a storm job or a big re-roof when the diary fills up. From the outside the line between an employee and a genuine subcontractor looks obvious to the roof plumber running the crew. In practice, the actual pattern of work on site often tells a different story.
Many roof plumbing businesses assume that if a worker has an ABN, raises an invoice, and owns their own folding gear and height safety equipment, the question is settled. The Fair Work Ombudsman's whole of relationship test page sets out that all of the factors in a relationship should be weighed together, and that having an ABN or sending an invoice does not automatically make someone a contractor. A subbie who has turned up to every box gutter and re-roof job for the business over a long run, taking direction on site the same way an employee would, can look very different once the whole relationship is looked at rather than just the paperwork.
What happens if a roof plumbing business gets this wrong?
Getting the classification wrong can leave a roof plumbing business in Australia exposed on tax, super, workers compensation and licensing all at once, often without anyone noticing until a storm season audit or an insurance claim brings it to the surface.
According to the Australian Taxation Office's page on the difference between employees and independent contractors, the business that engages a worker is responsible for classifying that worker correctly for tax and super purposes, and an incorrect decision can bring penalties. Workers compensation adds another layer. In New South Wales, icare's guidance on classifying workers or contractors says a business is not required to provide workers compensation insurance for contractors, other than a deemed worker, and points owners to the State Insurance Regulatory Authority's own tool to check which applies. Safe Work Australia's comparison of coverage for contractors and labour hire workers shows this is not the same everywhere: New South Wales and Victoria both use a deeming clause to bring some contractors into cover, while other states run their own separate tests. A roof plumber who has treated a long-term subbie as uncovered, only to find they are a deemed worker when someone falls from height off a steep metal roof, is finding this out the expensive way.
How do you tell a subcontractor from an employee on your own jobs?
You look at the whole relationship on each job, not any one feature of it. The ATO and the Fair Work Ombudsman both point to the same handful of questions: who controls how the work is done, whether the worker can delegate the job to someone else, whether the arrangement is ongoing or job by job, and who supplies the tools and plant.
The ATO's page on employee or independent contractor asks whether work can be delegated or subcontracted to another person as one of the deciding questions. A genuine subcontractor can usually send a qualified tradesperson in their place to finish the valley flashing or the box gutter if they are stuck on another job. An employee is generally expected to turn up themselves. The whole of relationship test adds the question of whether there is an ongoing expectation of work, noting that some employees are engaged for a specific task or project, so a one-off arrangement does not automatically point to a contractor either. For a roof plumber deciding who goes down as a subbie and who goes on the books, this is where your own job records carry more weight than memory. A pattern you can see across every re-roof, every storm callout and every compliance certificate signed off tells you whether a worker has been operating like a subcontractor or has quietly become a fixture in your crew.
Does the state you work in change the rules?
Yes, in two separate ways. Different states across Australia decide workers compensation cover for contractors differently, and licensing rules for who can actually sign off the plumbing work also differ between states, so a roof plumber taking jobs across a border needs to check both separately.
On licensing, Queensland's regulator says in when you need a licence that in most cases a subcontractor working for a licensed trade contractor does not need their own occupational licence, because the licensed contractor carries the responsibility, though anyone personally performing or supervising plumbing, drainage or gasfitting work as an employee of a licensed contractor still needs one. New South Wales runs it differently. Its page on plumbing, draining and gasfitting work says a licence or certificate is needed for any plumbing, draining or gasfitting work regardless of the cost of the job or whether it is residential, commercial or industrial, which leaves less room for a bare subcontracting arrangement to sidestep the licence question. Add the workers compensation comparison linked above, and it is clear a roof plumbing business cannot assume the answer that applied on a job in one state will hold on a job across the border.

How can AI agents help a roof plumbing business keep this straight?
Keeping the records this test actually asks for, who directed the work, who delegated what, how long someone has been on the books, is not a job most roof plumbers want done by memory at tax time. AI agents, software that does a job the way you would, using your own prices, wording and rules, can keep that history current as each job closes rather than leaving it to be reconstructed later. Another of these AI agents can flag it when a subbie's pattern starts looking like an employee's, before it becomes a workers compensation claim or an audit.
This is what a data first way of running the business looks like: the answer comes from what actually happened on the jobs, not from what the owner remembers happened. Greg coaches online and starts from your own job and pay data, so whether the business operates in New South Wales, Queensland or anywhere else in Australia does not change how the coaching works.
Where can you check the current rules?
- Employee or independent contractor: the ATO's full test, including the ability to delegate and the contract itself.
- Difference between employees and independent contractors: who is responsible for getting the classification right and what happens if it is wrong.
- Independent contractors: the Fair Work Ombudsman's overview and why it only advises rather than deciding.
- Whole of relationship test: the factors weighed together under the current test.
- Plumbing, draining and gasfitting work: New South Wales licensing requirements.
- When you need a licence: Queensland's subcontractor licensing position.
- Classifying Workers or Contractors for Workers Compensation: icare's guidance and the SIRA tool.
- Coverage of contractors and labour hire workers: how cover differs state by state.
How does Data First Coaching approach this?
Data First Coaching, built by Greg Allan, starts from a roof plumbing business's own job and pay records rather than from a description of how the business runs. On a question like subcontractor versus employee, the Trade Business Intelligence looks at the pattern across every re-roof, every storm job and every subbie on the books, because that pattern usually shows where the real risk sits before it shows up as a penalty or a claim. The how of setting this up, the records to keep and the agents to build around it, is worked through inside the Academy, with other members, because the Trade Business Intelligence is powered by every member and the Academy is built for owners who are open minded, innovative and willing to share what they learn.
