Plastering Cost per Square Metre in Australia 2026
Plastering happens at nearly every stage of a build or renovation — new plasterboard going up in a fresh room, a skim coat to freshen tired walls before painting, or a patch repair after a plumber ripped open a ceiling. Australian homeowners consistently underestimate the cost once ceiling heights, board type and finishing levels are factored in.
In 2026, plasterboard supply and installation across Australia sits broadly at $40–$65 per square metre for standard new work. Skim coating runs $15–$30/m², ceiling replacement $50–$90/m², cornice installation $6–$12 per linear metre, and patch repairs are typically a flat rate of $100–$300. All prices are indicative; your tradie will confirm the final price after assessing the job.
This guide covers every job type, what drives cost, when to patch versus rip out, and how to use Leadkit's free plastering cost calculator to get a ballpark in under a minute.

Plastering cost by job type
The table below covers the most common plastering jobs in Australian homes in 2026. Prices include supply of standard plasterboard, labour, and GST. Specialty board types (moisture-resistant, sound-rated, fire-rated) carry additional costs — see the board types section below.
| Job type | Typical rate | Notes |
|---|---|---|
| Plasterboard supply + install (walls) | $40–$65/m² | Standard 10 mm Gyprock, single layer |
| Plasterboard supply + install (ceilings) | $50–$75/m² | Higher labour rate for overhead work |
| Skim coat (over existing surface) | $15–$30/m² | One–two coats of finish plaster (set) |
| Cornice installation | $6–$12/linear metre | Cove or ogee profile, supply + fix |
| Full ceiling replacement | $50–$90/m² | Remove, dispose, re-sheet, stop, prime |
| Patch repair (small holes, cracks) | $100–$300 flat | Usually flat rate regardless of m² |
| Level 4 finish (standard) | Included in base rate | Suitable for paint or light texture |
| Level 5 finish upgrade | Add $5–$12/m² | Skim + sand for gloss paint or veneer |
These ranges are based on estimates generated through Leadkit's plastering cost calculator using current Australian rates. This is a price indication only. Your tradie will confirm the final price after assessing the job.
Methodology note: Leadkit's plastering calculator multiplies a per-m² supply-and-install rate by the measured area, then applies board-type surcharges and finish-level adjustments. The rates in this table reflect the mid-range inputs used by plasterers across Australia who have set up their own calculators on the platform.
City-by-city cost comparison
Labour rates vary materially across Australian cities, driven by local award wages, demand for tradies and the general cost of doing business. Sydney and Melbourne sit at the top; Brisbane and Adelaide typically come in lower.
| City | Plasterboard install (per m²) | Skim coat (per m²) | Ceiling replacement (per m²) |
|---|---|---|---|
| Sydney | $55–$75 | $22–$35 | $65–$95 |
| Melbourne | $50–$70 | $20–$32 | $60–$90 |
| Brisbane | $45–$65 | $18–$28 | $55–$80 |
| Perth | $48–$68 | $20–$30 | $58–$85 |
| Adelaide | $42–$60 | $16–$26 | $50–$75 |
This is a price indication only. Your tradie will confirm the final price after assessing the job.
Australian Bureau of Statistics (ABS) construction cost data shows labour costs in Sydney and Melbourne up approximately 6–8% since 2024, driven by sustained housing activity and tight trades availability.
What drives the cost of plastering?
Room size and minimum call-out
Plasterers work more efficiently on large open areas — a single 40 m² living room costs less per m² than three small bedrooms of the same total area. Most plasterers apply a minimum job fee of $250–$400, so tiny patch jobs can seem expensive on a per-m² basis.
Ceiling height
Standard ceiling height in Australian homes is 2.4 m. Every extra 300 mm adds scaffolding, harder sheet manoeuvring and longer stopping time. Ceilings above 3 m typically add $8–$15/m² to the base rate.
Number of coats and finish level
Stopping is the process of filling screw holes and joints with compound (also called set — the gypsum-based plaster mix). A Level 4 finish — standard for walls painted in low-sheen — includes taping, two coats of compound and a light sand. A Level 5 finish adds a full skim coat across the entire board surface, sanded smooth: required for gloss paints and direct-lighting situations, and adds $5–$12/m².
Access and site conditions
Disposal of old plasterboard adds $8–$15/m² to any replacement job. High-rise apartments and tight townhouses cost more than single-storey homes with direct truck access. Asbestos-containing plaster (common before 1990) requires licensed removal — a separate cost entirely. The Housing Industry Association (HIA) recommends a pre-renovation asbestos inspection for any home built before 1987.
Board type
Standard 10 mm CSR Gyprock is the baseline. Specialty boards from CSR, USG Boral and other manufacturers carry premiums — see the next section.
Plasterboard types and cost premiums
Not all plasterboard is equal. Choosing the right board for each application is as important as the installation quality.
| Board type | Typical premium over standard | Where it's used |
|---|---|---|
| Standard 10 mm Gyprock | — (baseline) | Internal walls and ceilings, dry areas |
| Moisture-resistant (MR board) | +$4–$8/m² | Bathrooms, laundries, kitchens |
| Sound-rated (acoustic) | +$10–$20/m² | Shared walls in apartments/duplexes |
| Fire-rated (Type X) | +$12–$25/m² | Garage/laundry separation, commercial |
| Impact-resistant | +$6–$12/m² | Hallways, rumpus rooms, high-traffic walls |
This is a price indication only. Your tradie will confirm the final price after assessing the job.
Moisture-resistant board (MR board or Aquachek) uses a treated core and water-repellent face paper. It's not waterproof — tile adhesive and waterproofing membranes are still required in wet areas — but it significantly improves durability if moisture ever penetrates the tile layer.
Sound-rated boards (USG Boral SoundStop or CSR AcoustiX) use a denser core, sometimes with a Rondo resilient-mount steel frame system. In apartments and duplexes, the National Construction Code (NCC) requires minimum sound-transmission class (STC) ratings between tenancies — sound-rated boards are usually the simplest path to compliance.
Fire-rated boards (Type X, typically 16 mm) are mandatory at fire-separation boundaries — most commonly between an attached garage and the house, or a laundry and living areas. Under-specifying here is a genuine safety and insurance risk; confirm the spec with your certifier.
Patch vs full rip-out: the decision guide
This is the question homeowners most frequently get wrong — spending money on patch repairs that fail within 12 months, or over-investing in full rip-outs when a good patch would have been perfectly fine.
Patch when:
- The affected area is under 0.5 m² and surrounding board is structurally sound (press firmly — no flex or crunch).
- There is no moisture damage or mould on the back face.
- The repair is in a low-visibility area and the existing installation is less than 20 years old.
Rip out and re-sheet when:
- Water damage or cracking covers more than 1–2 m².
- The plaster is original to a pre-1990 home with widespread hairline cracking — a sign of age-fatigue, not just surface wear.
- You are renovating the room anyway (marginal cost of fresh sheeting during a reno is minimal compared to doing it twice).
- Any possibility of asbestos in the existing material — test first, don't cut or drill until you know.
- Sound or fire performance is being upgraded, which requires full removal and re-lining to the new spec.
Across quotes processed through Leadkit, the most common homeowner regret is patching a water-damaged ceiling: the repair holds visually for a while, but residual moisture causes the join to re-crack within 12–18 months.
Ceiling replacement cost breakdown
Ceilings consistently cost more per m² than walls — typically 20–30% more for equivalent work. Here is why.
Overhead work. Every task is done above shoulder height. Labour productivity drops roughly 25–30% compared to wall work, and ceiling jobs often need two tradies on-site.
More stopping coats. Ceiling joints catch raking light, making any imperfection visible. A Level 4 finish on a ceiling typically needs an extra coat of compound compared with the same finish on a wall.
Disposal. Pre-1990 homes may have asbestos in the old ceiling material — get it tested by a NATA-accredited lab before any cutting or demolition. Asbestos disposal requires a licensed removalist and can significantly increase total project cost.
For a 15 m² bedroom ceiling replacement (demolition, disposal, re-sheet, stop, prime) expect $750–$1,350. For a larger open-plan area of 35–40 m², that range moves to $1,750–$3,600.

How to get quotes and use the calculator
Getting three quotes for any plastering job over $1,500 is standard practice recommended by Master Builders Australia. When briefing a plasterer, have ready: the total wall and ceiling area, board type required, finish level (Level 4 for standard paint, Level 5 for gloss), and whether disposal of old material is included.
Use the Leadkit calculator first. The free plastering cost calculator lets you select job type, enter the area, choose board spec and finish level, and returns an instant ballpark using current Australian rates — useful for sense-checking quotes before you call anyone.
After plastering, most rooms need painting. Our painting quote calculator covers that next step. For broader renovation context, the house painting cost guide and the bathroom renovation cost guide for Sydney are worth reading alongside this one.

FAQ
Q: How much does it cost to plaster a room in Australia in 2026?
A: Plastering a standard bedroom (roughly 40 m² of wall area) with new plasterboard to a Level 4 finish costs approximately $1,600–$2,600 in most Australian cities. Sydney and Melbourne sit at the upper end; Adelaide and Brisbane typically come in lower. Ceiling height, number of openings, and whether disposal is included all affect the final figure. This is a price indication only — your tradie will confirm the final price after assessing the job.
Q: Is plasterboard cheaper than wet plaster?
A: Yes, in almost every situation. Plasterboard (also called Gyprock or drywall) is faster to install, needs less drying time and requires less skilled labour than traditional wet plaster (a sand-and-cement or lime-based system applied in multiple layers). Wet plaster costs $45–$90/m² and is rarely specified in new Australian residential construction. It still appears in renovations of older homes where matching existing texture matters, or in high-end custom builds where a harder wall finish is required.
Q: What is a skim coat and when do I need one?
A: A skim coat (also called a set coat) is a thin layer of finishing compound — 1–3 mm — applied over an existing surface to create a smooth, uniform base for paint. You need one when the plasterboard is structurally sound but the surface has tape lines, paint build-up or old texture that would show through new paint. At $15–$30/m² it's the most cost-effective way to refresh a room before repainting. It's not a substitute for patching — fix holes and soft spots first. This is a price indication only. Your tradie will confirm the final price after assessing the job.
Q: Do I need sound-rated plasterboard in an apartment or duplex?
A: Almost certainly yes. The NCC requires minimum sound-transmission class (STC) ratings between sole-occupancy units. In practice this means sound-rated boards (CSR AcoustiX, USG Boral SoundStop) on a Rondo resilient-mount steel frame with acoustic insulation batts. The exact requirement depends on building class and the performance pathway your certifier is using. Getting it wrong can mean costly rectification work — check the spec before ordering materials.
Q: What is a Level 5 finish and when is it worth paying for?
A: Level 5 is the highest standard of plasterboard finishing — a full skim coat of compound across the entire board surface, then sanding to near-flat. It adds $5–$12/m² over Level 4. Worth the premium in rooms where gloss or semi-gloss paint will be used, under raking light from skylights or downlight arrays, and in high-end kitchens or bathrooms. For a room painted with standard flat white ceiling paint, Level 4 is perfectly adequate.
Q: How much does ceiling plastering cost compared to wall plastering?
A: Ceilings cost roughly 20–30% more per m² than equivalent wall work. Plasterboard supply and install on walls runs $40–$65/m²; on a ceiling $50–$75/m². Full ceiling replacement (demolition, disposal, re-sheet, stop, prime) is $50–$90/m². The premium is driven by overhead labour intensity, extra stopping coats needed for a smooth finish under lighting, and the fact that most ceiling jobs need two tradies. This is a price indication only. Your tradie will confirm the final price after assessing the job.
