At a Glance
The single biggest cost variable in Melbourne plasterboard work is not the board itself. It is the additional requirements that come with it: fire-rated assemblies between attached dwellings, acoustic treatment for noise-sensitive rooms, and high ceilings in period homes that make overhead work slower. Expect $750–$7,600 per job for standard installation.
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
- Internal and external corner finishing
- Cornice (cove or square-set) if included in the scope
Framing, insulation installation, electrical and 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, multiple layers, and rated compounds, all of which add cost.
- Acoustic treatment. Inner-city conversions (warehouses to apartments, commercial to residential) and terrace house renovations increasingly specify acoustic assemblies. Acoustic board plus insulation plus resilient mounts significantly reduces noise transfer 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, scaffolding inside the room, and more difficult overhead work. Budget 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.
- Board type. Standard 10mm or 13mm is the baseline. Moisture-resistant board for bathrooms, impact-resistant board for garages, and fire-rated board all cost more.
- Finish level. Level 4 is standard. Level 5 (full skim coat) is increasingly requested in modern Melbourne renovations where clean-lined interiors and 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's renovation culture generates a high volume of plasterboard work. 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.
Townhouse developments across the middle suburbs (Richmond, Prahran, Brunswick, 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. 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 a higher standard of finish at the join (Level 5 locally) and careful framing alignment. It is more labour-intensive than installing cove cornice, not less. If your plasterer quotes less for square-set than cornice, question whether they 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.
When hiring a plasterer for plasterboard installation:
- Ask for trade qualifications (Cert III in Wall and Ceiling Lining)
- Confirm experience with fire-rated and acoustic assemblies if your project requires them
- Request the finish level in writing
- Ask about dust management, particularly in occupied homes
- Verify public liability insurance
For fire-rated work, the plasterer should be able to show you the specific system they are installing (e.g., a CSR or Knauf fire-rated wall system) and confirm it meets the FRL specified by your building surveyor.
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.
