What's Included in the Price
- Supply of plasterboard sheets (standard, fire-rated, moisture-resistant, or acoustic as required) compliant with AS/NZS 2588
- Fixing to timber or steel framing
- Jointing, taping, setting, and sanding per AS/NZS 2589 (Level 4 standard residential finish)
- Internal and external corner finishing
- Cornice (cove or square-set) if included in the scope
Supply-and-fix rates in Melbourne sit at $18–$24/m2 for standard wall lining, rising to $26–$34/m2 for ceiling work and $32–$42/m2 for fire-rated or acoustic assemblies. Framing, insulation installation, electrical rough-in, plumbing rough-in, and painting are typically separate scopes. Confirm at the quoting stage which trades are included and which need separate coordination.
What Affects the Cost
- Fire-rated requirements. Walls between attached townhouses, between a garage and living space, or between units must meet fire resistance levels specified in the NCC. This means specific board types such as CSR Gyprock Fyrchek or Knauf Firestop ($35–$45/sheet), potentially in double layers, with rated compounds. This adds $10–$20/m2 over standard board.
- Acoustic treatment. Inner-city conversions (warehouses to apartments, commercial to residential) and terrace house renovations increasingly specify acoustic assemblies. Acoustic board (Gyprock Soundchek, $30–$40/sheet) plus insulation plus resilient mounts can reduce noise transmission by 15–20 dB but adds to the per-square-metre price.
- Ceiling height. Melbourne's period homes (Victorian, Edwardian, interwar) often have ceiling heights of 3m or more. This means longer sheets (3000mm minimum), internal scaffolding, and more difficult overhead work. Budget 20–30% more per square metre for high ceilings.
- Total area. Larger jobs reduce the per-square-metre rate. A full renovation with multiple rooms is more cost-effective than a single partition wall, which carries a minimum charge.
- Board type. Standard 10mm ($12–$18/sheet) or 13mm ($16–$24/sheet) is the baseline. Moisture-resistant board for bathrooms ($22–$32/sheet), impact-resistant board for garages ($35–$50/sheet), and fire-rated board all cost more.
- Finish level. Level 4 is standard. Level 5 (full skim coat, $5–$10/m2 extra) is increasingly requested in modern Melbourne renovations where clean-lined interiors and LED feature lighting demand a flawless surface.
A standard partition wall in a post-2000 townhouse with cove cornice sits toward $750. A full renovation in a Victorian terrace with high ceilings, fire-rated party walls, acoustic treatment, and Level 5 finishing pushes toward $7,600.
Melbourne-Specific Considerations
Melbourne generates some of the highest plasterboard volumes in Australia. Period homes across the inner suburbs are continuously being updated, and plasterboard is central to nearly every residential renovation.
In Fitzroy, Carlton, South Yarra, and Hawthorn, renovations to Victorian and Edwardian homes frequently involve lining over original brick or stone walls with plasterboard on furring channels. This creates an insulated, flat surface suitable for modern paint finishes. The trade-off is a small reduction in room dimensions (25–40mm per wall), which matters in already narrow terrace floor plans. The upside is that insulation batts can be fitted in the gap behind the board, improving both thermal and acoustic performance of solid masonry walls.
Townhouse developments across the middle suburbs in Richmond, Prahran, Brunswick, and Coburg require fire-rated party walls between attached dwellings. This is a NCC requirement, not optional. The builder or building surveyor specifies the required fire resistance level (typically FRL 60/60/60 for inter-tenancy walls), and the plasterer must install accordingly. A compliant system uses fire-rated board (pink-faced paper, denser core) in the correct layering with rated compounds. Using the wrong board or missing a layer is a compliance failure that can be picked up at inspection.
Square-set finishes (no cornice, clean right angle at the wall-ceiling join) have become the default in many Melbourne renovation projects. This looks simple but requires Level 5 finishing at the junction and careful framing alignment. It is more labour-intensive than installing standard cove cornice, not less. Square-set typically runs $15–$25 per lineal metre versus $8–$15/lm for cove cornice. A plasterer who quotes less for square-set than cornice may not understand the finish standard involved.
Hiring a Licensed Plasterer in VIC
In Victoria, single-trade plastering work does not require registration with the Victorian Building Authority (VBA). However, when plastering is part of a larger building project involving multiple trades, the builder overseeing the project typically needs VBA registration. You can search for registered practitioners on the VBA practitioner search.
A good plasterer will:
- Hold trade qualifications (Cert III in Wall and Ceiling Lining, CPC31920)
- Confirm experience with fire-rated and acoustic assemblies if your project requires them
- Specify the finish level in writing (Level 4 standard, Level 5 if requested)
- Explain their dust management approach, particularly in occupied homes
- Carry current public liability insurance
Worth checking:
- For fire-rated work, they can show you the specific system being installed (e.g., a CSR Fyrchek or Knauf Firestop wall system) and confirm it meets the FRL specified by your building surveyor
- The quote separates board type, finish level, and cornice/square-set costs so you can compare like-for-like
- They have experience with your property type (period home masonry lining vs modern framed construction)
How We Calculate
Estimates are based on current plasterer rates in the Melbourne metropolitan area, adjusted for property age and typical construction in VIC. All prices include GST. Figures cover plasterboard supply, fix, and finish. Framing, insulation, electrical rough-in, and painting are excluded unless noted.
