How to Become A Joiner

What is a Joiner

A joiner cuts, shapes and fits timber parts in a workshop. The finished pieces are installed in homes and commercial buildings. They make doors, window frames, staircases and kitchen cabinetry.

Most joinery happens in a dedicated workshop, not on a building site. Joiners read technical drawings and pick the right timber or materials. They use machines and hand tools to craft each piece to exact dimensions.

Day-to-day work involves measuring and cutting timber, forming wood joints, assembling parts and applying finishes. You also check your work against drawings before it goes to site. Attention to detail matters at every step.

About 4,300 joiners work in Australia, and 83% are full-time (Your Career, 2025). Future demand is rated moderate, driven by steady construction activity. It suits anyone who likes hands-on work and takes pride in what they make.

Joinery has a steady outlook across Australia. Around 4,300 people work as joiners, with 83% in full-time roles. The average working week is 42 hours (Your Career, 2025).

The median age of a joiner is 36 years. Almost half of all joiners are under 35. It is a young trade with plenty of room to grow. Future demand is rated moderate by the Australian Government. Residential construction and commercial fit-out both drive demand for skilled joiners. The median weekly wage is $1,787, or about $93,000 a year (Your Career, 2025).

After qualifying, many joiners move into cabinetmaking, carpentry, construction supervision or self-employment. The skills are transferable. Experienced joiners with specialist knowledge can earn more and progress to senior roles or run their own workshop.

Steps to Become a Joiner

Step 1: Complete Year 10 and build your foundation skills

Finish Year 10 (or similar) with a focus on maths and technical drawing. These subjects help you read blueprints and work to precise measurements. Both are core skills in joinery. Woodwork or building subjects at school give you a useful head start.

Step 2: Secure a joinery apprenticeship

Apply through a joinery workshop, a building company or a Group Training Organisation (GTO). Apprenticeships last three to four years. They combine on-the-job learning with formal training. Contact your state apprenticeship body to find registered employers.

Step 3: Complete the Certificate III in Joinery (CPC31920)

Your apprenticeship leads to the Certificate III in Joinery (CPC31920), delivered by a TAFE or RTO. This cert covers timber selection, joint cutting, workshop machines, surface finishing and building codes. It takes three to four years to complete via an apprenticeship. Confirm the current code on training.gov.au if needed.

Step 4: Obtain any required state or territory licence

Some states require joiners to hold a contractor or trade licence before working on their own. Check with your state building regulator to find out what applies. Examples include NSW Fair Trading, the QBCC and the Victorian Building Authority (VBA). Allow four to eight weeks to process your application.

Step 5: Build experience and consider a specialisation

After qualifying, work across home, commercial and fit-out projects to build your range. Many joiners focus on cabinetry, staircases, shop fitting or high-end joinery. Specialising can boost your pay and lead to supervisory work or your own business. Bodies like Master Builders Australia and the HIA run short courses to help you grow.

What does a Joiner do?

On a typical day, a joiner works in a workshop measuring, cutting and assembling timber parts from technical drawings. In the morning you might be making door frames. By afternoon you could be cutting joints for a staircase. You will operate machines like planers and routers, check your work against specs, and keep your workspace safe and tidy. It is hands-on, detail-focused work where you can see exactly what you built by the end of each day.

Tasks

Joiners craft timber structures and fittings in workshops for homes and commercial buildings. Here is a snapshot of what the job involves day to day.

  • Read blueprints: study technical drawings to work out what to make and what materials to use.
  • Cut and shape timber: use hand tools and powered machines to cut parts to precise dimensions.
  • Form wood joints: cut mortise-and-tenon, dovetail and other joints so components fit together cleanly.
  • Assemble fittings: join parts to make doors, window frames, staircases, cabinetry and other fixtures.
  • Apply finishes: sand, stain and lacquer surfaces to protect the wood and meet design needs.
  • Check quality: measure finished pieces against drawings to make sure everything is within tolerance.
  • Maintain tools and equipment: keep machines and hand tools clean and in safe working condition.
  • Work safely: follow WHS procedures and keep the workshop clean and hazard-free.

Skills for Success

To do well as a joiner, you need a sharp eye for detail and solid maths skills. Accurate measurements are what make everything fit together correctly. You also need to read technical drawings, which takes practice but soon becomes second nature.

You will use hand tools and powered machines in the workshop. Good hand-eye coordination and safe work habits are a must. Problem-solving helps when a design gets tricky. Clear talk with builders and clients keeps each project on track.
