Plasterboard Installation Cost per Square Metre in Australia 2026
Plasterboard installation costs $40–$65 per square metre in Australia in 2026 for standard supply and install on walls, inc. GST. Board and skim together runs $55–$95/m², a skim coat alone is $15–$30/m², and ceiling replacement sits at $50–$90/m². The average cost of plastering across all job types lands near $50/m².
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.
Cornice installation adds $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.

Key takeaways
- Plasterboard supply and install costs $40–$65/m² inc. GST across most of Australia for standard 10 mm Gyprock on walls.
- Board and skim costs $55–$95/m² — the plasterboard install rate plus a $15–$30/m² skim coat over the top.
- A skim coat over existing walls costs $15–$30/m² — the cheapest way to refresh a room before repainting.
- Gyprocking a whole 200 m² house costs roughly $22,000–$45,000, because wall and ceiling lining area runs about 3–3.5× the floor area.
- Ceiling replacement costs $50–$90/m², more than walls, because of overhead work and extra stopping coats.
- Sound-rated and fire-rated boards add $10–$25/m² over standard Gyprock.
- Patch repairs under 0.5 m² are charged flat, $100–$300, not per m².

How much does plasterboard installation cost per square metre?
Plasterboard installation costs $40–$65 per square metre on walls and $50–$75 per square metre on ceilings in Australia in 2026, including supply of standard 10 mm board, labour and GST. Add $15–$30/m² if you want a skim coat over the new sheets — a "board and skim" job — which puts the combined rate at $55–$95/m².
The table below covers the most common plastering jobs in Australian homes. 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 |
| Board and skim (install + skim coat) | $55–$95/m² | New sheets then a full set coat |
| 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 calculators 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.
What does plastering cost in each Australian city?
Plasterboard installation is most expensive in Sydney at $55–$75/m² and cheapest in Adelaide at $42–$60/m². Labour rates vary materially across Australian cities, driven by local award wages, demand for tradies and the general cost of doing business. Melbourne sits just under Sydney; Brisbane and Perth land in the middle.
| 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?
Five things move a plastering quote: the size of the area, ceiling height, the finish level, site access, and the board type specified. Each one is worth understanding before you compare quotes, because two plasterers quoting different numbers are often quoting different scopes.
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.
Which plasterboard type do you need and what does it add?
Moisture-resistant board adds $4–$8/m², impact-resistant adds $6–$12/m², sound-rated adds $10–$20/m² and fire-rated adds $12–$25/m² over standard 10 mm Gyprock. Choosing the right board for each application is as important as the installation quality — and specifying it up front stops a quote moving after work starts.
| 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.
Should you patch or rip out and re-sheet?
Patch when the damage is under 0.5 m² and the surrounding board is dry and solid; rip out and re-sheet when damage exceeds 1–2 m², moisture is involved, or the board is pre-1990 with widespread cracking. 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.
Why does ceiling replacement cost more than walls?
Ceiling work costs 20–30% more per square metre than equivalent wall work — $50–$90/m² for a full replacement — because everything is done overhead, joints need an extra stopping coat, and most ceiling jobs need two tradies. Here is how that breaks down.
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.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
How do you get quotes and use the calculator?
Get three quotes for any plastering job over $1,500, and give every plasterer the same four numbers: total wall and ceiling area, board type, finish level, and whether disposal is included. Three quotes on identical scope is standard practice recommended by Master Builders Australia — and identical scope is what makes the numbers comparable.
Use the Leadkit calculator first. It 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. It's Leadkit's own tool, built on the rates Australian plasterers set up on the platform, not neutral third-party data.
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.

Frequently asked questions
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: What is the average cost of plastering per square metre in Australia?
A: The average cost of plastering in Australia in 2026 is about $50 per square metre, sitting mid-way in the $40–$65/m² supply-and-install range for standard plasterboard on walls. Skim-only work averages closer to $22/m², and ceiling replacement averages about $70/m². Averages are useful for a first sense-check, but the spread matters more than the midpoint: board type, ceiling height and city can each move your rate by $10–$25/m². Run your own numbers through the construction and building calculators rather than budgeting off an average alone.
Q: How much does gyprocking a house cost?
A: Gyprocking a typical 200 m² single-storey Australian home costs roughly $22,000–$45,000 inc. GST in 2026. The reason the number is so much larger than the floor area suggests: total wall and ceiling lining area is usually 3–3.5× the floor area, so a 200 m² house has around 600–700 m² to sheet at $40–$65/m². Cornice, Level 5 upgrades and specialty boards push it higher. This is a price indication only. Your tradie will confirm the final price after assessing the job.
Q: What does board and skim cost per m²?
A: Board and skim costs $55–$95 per square metre in Australia — new plasterboard supplied and installed at $40–$65/m², plus a full skim coat at $15–$30/m² over the top. You only need the skim if you want a glass-flat surface for gloss paint, raking light or a wallpaper-grade finish. For standard low-sheen paint, a Level 4 stopped finish is already included in the base install rate, and paying for a skim on top of it adds cost you won't see on the wall.
Q: How much does cement plastering cost per square foot?
A: Australian plasterers quote in square metres, not square feet, but the conversion is straightforward: cement-based wet plaster and render runs $45–$90/m², which is about $4.20–$8.40 per square foot (1 m² = 10.76 sq ft). Wet plaster is a sand-and-cement or lime-based system applied in multiple layers, mostly used on external walls, older solid-wall homes, and heritage restorations. Internal work in Australia is almost always plasterboard instead.
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. 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.
