Diploma of Beauty Therapy in Australia (SHB50121): Full Guide

If you are serious about a career in beauty, the Diploma of Beauty Therapy is the qualification that opens the most doors. It is the industry standard for a fully qualified beauty therapist — the level of training that lets you offer advanced treatments, manage a salon, or move into specialised skin work. This guide explains what the diploma of beauty therapy covers, how long it takes, the entry requirements, and where it can take your career.

What is the Diploma of Beauty Therapy?

The nationally recognised qualification is SHB50121 – Diploma of Beauty Therapy, listed on training.gov.au. It reflects the role of a fully qualified beauty therapist who provides a broad range of treatments and services, consults with clients, recommends treatments, and sells retail skincare and cosmetics. To achieve it, you complete a total of 29 units of competency — 20 core and 9 electives.

What you’ll learn

The diploma of beauty therapy goes well beyond entry-level skincare. Across the course you build advanced, salon-ready skills including:

• Advanced facial treatments and skin analysis
• Body massage, body treatments and relaxation techniques
• Hair removal, including waxing
• Lash and brow treatments
• Nail and make-up services
• Client consultation, treatment planning and retail advice

You also learn to work autonomously and take responsibility for your own results — the professional judgement employers expect from a diploma-qualified therapist.

Entry requirements

To enter SHB50121 you generally need to have completed Year 12 (or equivalent) and hold a Certificate III in Beauty Services (some providers accept a Certificate IV or higher, or relevant experience). If you are weighing up where to start, our comparison of a Certificate III vs Diploma explains how the two levels fit together.

How long does the diploma of beauty therapy take?

Most students complete the diploma in 6 to 12 months, depending on the provider, study mode and electives chosen — full-time study is faster, while part-time or evening study spreads it out. Because it is a nationally recognised qualification, eligible students may also be able to access subsidised or government-funded training.

Career outcomes

A diploma of beauty therapy qualifies you to work as a beauty therapist in spas and salons in Australia and overseas, to work freelance or from home, and — importantly — to manage or open your own salon and employ staff. It is also the springboard into specialised, higher-earning skin careers: see our guides on how to become a beauty therapist, the beauty therapist salary in Australia, and moving into advanced skin work as a dermal therapist.
