Interior Design vs Interior Decoration: Which Path Is Right for You?
Before choosing a course, it\'s worth understanding how these two terms are used in the Australian market — because the distinction affects both your study options and your future work scope.
| Aspect | Interior Design | Interior Decoration |
|---|---|---|
| Focus | Space planning, structure, technical drawings | Colour, texture, furniture, styling |
| Projects | Commercial, large residential, architectural | Residential, boutique commercial, staging |
| Tools | AutoCAD, Revit, SketchUp (technical) | Mood boards, InDesign, RoomSketcher |
| Regulation | Not licensed in AU (no statutory requirement) | Not licensed in AU |
| Qualification level | Diploma or degree preferred for commercial work | Cert IV sufficient for most residential work |
| Starting salary | $50,000–$70,000 AUD | $45,000–$65,000 AUD |
The Australian national qualifications framework uses "Interior Design and Decoration" as a unified discipline at vocational level. Most working professionals straddle both in practice — particularly those running their own studios.
