How Much Does Plastering Cost In Australia

Most plastering jobs in Australia cost between $20 and $90 per square metre, with wall only work in a small room starting from about $300 and plastering an entire home often ranging from $7,000 to $15,000 or more. The exact cost of plastering depends on the type of plaster, square metre rates, labour costs, access and how much work is needed on any existing plaster.

As a national trades directory, Trade Heroes sees real plastering prices every day. This price guide will walk you through typical costs, the main plastering techniques, what drives the final price of your plastering project and how to find plasterers you can trust.

Average Cost Of Plastering

The average cost of plastering in Australia usually sits between $20 and $90 per square metre, with most standard indoor plastering jobs sitting in the middle of that range. Simple plasterboard installation on straight walls will generally cost less, while wet plaster and ornamental plastering sit at the higher end.

Typical costs per square metre are:

• Hard plaster on solid walls: $20 to $70 per square metre
• Wet plaster on walls or ceilings: $45 to $90 per square metre
• Installing plasterboard only: $8 to $16 per square metre
• Plasterboard supply and install: $15 to $20 per square metre

Ceiling plastering is usually more labour intensive than walls and often ranges from $25 to $35 per square metre. In Melbourne, average rates for some standard plastering work are around $20 to $25 per square metre, while Sydney and Perth usually sit higher.

The Australian Taxation Office publishes benchmark rates for plastering jobs that closely match these figures, especially for plasterboard and Gyprock work. Those benchmark rates are a good cross check when you are comparing quotes.

Remember that square metre or square meter pricing is only one part of the overall cost. The type of plaster, the condition of the surfaces, other materials like cornices or specialty boards and the plasterer’s hourly rate all affect what you actually pay.

Plastering Costs By Job Type (Walls, Ceilings, Whole Room/Home)

Most homeowners want to know how much does plastering cost for a specific job such as one room, one ceiling or an entire house, not just the rate per square metre. These ranges will help you sanity check any plastering cost you are quoted.

Cost To Plaster Walls

Plastering the walls of a small room usually costs between $300 and $500 if it includes walls only, while a medium room often costs $900 to $1,500 and a large room might cost $1,500 to $2,500 for wall plastering. These typical costs assume standard drywall or plasterboard and no structural issues with old plaster.

You can expect to pay:

• Small wall area or feature wall: $300 to $500
• Medium wall area in most rooms: $900 to $1,500
• Large wall area or open space: $1,500 to $2,500

The overall cost climbs if the job involves removing old or damaged material, complex plaster repairs, moisture treatments or cement based finishes. Plastering costs can escalate quickly when extensive preparation is required.

Cost To Plaster Ceilings

Ceilings generally cost more than walls because access is harder and the plastering work is more labour intensive. Standard ceiling plastering usually sits between $25 and $35 per square metre, with small ceilings from around $380 and large or high ceilings reaching $2,800 or more.

Higher plastering prices apply where:

• Scaffolding is needed to reach high ceilings
• There are decorative effects, bulkheads or complex shapes
• Existing plaster must be removed and a straight final coat applied

Cost To Plaster An Entire Room

Plastering an entire room, including walls and ceilings, costs more than wall only work but often delivers better value than staging separate visits. For a typical bedroom or living room you can expect to pay:

• Small entire room: $1,100 to $1,500
• Medium entire room: $1,500 to $2,000
• Large entire room or feature space: $2,000 to $3,000+

Combining plastering jobs such as walls and ceilings into one plastering project can save money by reducing travel and set up time. A good plasterer will explain whether a flat rate or fixed price makes more sense for your situation.

Cost To Plaster An Entire Home

Plastering an entire home is a major investment and prices vary widely. As a rough guide, plastering an entire house can cost:

• Small home: $3,600 to $4,700
• Average family home: $7,000 to $10,000
• Large or ornate house: $10,000 to $20,000+

On big projects the square metre rates may be slightly lower, but the final price is still high because more materials and hours are required. For these jobs, Trade Heroes plasterers usually provide a comprehensive breakdown so you can see where the price is coming from.

Types Of Plaster And Plastering Methods

Choosing the right type of plaster and method is one of the best ways to control plastering cost while still getting a durable finish.

Drywall plaster and standard Gyprock are the preferred choice for most builders because they are affordable, quick to install and provide fire resistant and sound insulation options. Standard gypsum plasterboard is cheaper than cement based boards and can save money in most rooms, while cement based boards for wet areas often cost 10 to 15 percent more but offer better moisture resistance.

Common plastering techniques include:

• Hard plaster
• Applied directly to masonry or curved surfaces where plasterboard is not practical. Hard plaster gives a very durable wall finish but can cost more per square metre.
• Wet plaster
• A traditional mix of lime plaster, cement and water applied with a trowel. Wet plaster is ideal for some heritage jobs and can be used as a smooth final coat, but it takes longer to dry than drywall and can slow your renovation timeline.
• Lime plaster
• Made from lime and sand, often used as both undercoat and finished surface in older houses.
• Gypsum plaster
• Increasingly popular because it shrinks less, cracks less and is versatile as an undercoat, finish coat or one coat product.
• Standard plastering versus skimming
• Standard plastering is usually done in new buildings to smooth rough bases, while skimming is a thin coat of plaster over old plaster in existing buildings to refresh the surface.
• Ornamental plaster
• Used for cornices, ceiling roses and other decorative effects. Cornices generally cost between $10 and $30 per linear metre, and ceiling roses typically range from $150 to $500 each, separate from normal wall or ceiling pricing.

Ornamental work is more labour intensive and often requires a specialist plasterer, so expect to pay more for these finishes.

Factors That Affect Plastering Prices

Plastering costs can vary a lot between properties, even when they have the same floor area. Understanding the main drivers helps you plan and get an accurate quote.

Key factors include:

• Size Of The Job
• More walls, ceilings, rooms and an entire home naturally increase the total cost, even if the per square metre rate drops slightly on larger projects.
• Type Of Plaster And Boards
• Cost effective plasterboard, mid range hard plaster and more expensive wet plaster or specialty finishes all sit at different price points. Specialty boards such as fire rated or moisture resistant plasterboard generally cost more but may be essential in wet areas.
• Condition Of Existing Plaster
• Extensive preparation on damaged or crumbly old plaster, or major plaster repairs, can increase plastering costs substantially. Jobs that involve removing old material or adding special finishes will always cost more.
• Location And Labour Costs
• Labour costs for plastering typically range from $45 to $105 per hour, with higher hourly rate figures in big cities and premium suburbs.
• Access And Complexity
• Curved walls, stairwells, exterior work and high ceilings are harder to reach and more labour intensive. Complex plastering techniques take longer and increase the cost.
• Materials And Extras
• Decorative work, specialty boards, undercoats and other materials add to the bill. Decorative plastering and wet areas generally cost more than standard rooms.

Planning the job properly and giving your plasterer clear access helps them work faster and more efficiently, which can lower the overall cost.

Benefits Of Plastering Your Home

Quality plastering gives your house a smoother, stronger and more durable finish than simply painting over rough surfaces.

Key benefits include:

• Durable Wall Finish
• Plaster creates a dense, durable finish that stands up better to knocks than many lightweight alternatives.
• Sound And Heat Performance
• Properly plastered walls and ceilings, combined with the right boards, improve sound insulation and help keep rooms more comfortable.
• Fire And Moisture Performance
• Many plaster systems are fire resistant, and moisture resistant boards in wet areas improve long term performance.
• Design Flexibility
• Ornamental plastering allows curves, niches, cornices and decorative effects that simple drywall alone cannot provide.
• Environmental Benefits
• Many plasters are pollution free, low in odour and a better option for healthy living spaces.

Done well by a professional plasterer, a single well planned plastering project can save money on future repairs and repainting.

What To Consider When Hiring A Plasterer

The plasterer’s experience often matters as much as their rate per square metre. A good plasterer will give you a smooth finish, a fair final price and a clear, detailed quote.

When you compare plasterers on Trade Heroes, look for:

• Licensing And Insurance
• In many states, plastering work falls under a builder's licence. Always confirm licensing and insurance before you pay a deposit.
• Relevant Experience And Previous Work
• Ask about previous work on similar jobs, whether that is new builds, entire home projects, repairs, or ornamental plastering. Check photos and reviews so you can see their plastering techniques in action.
• Written Quote And Scope
• Request a written quote that lists materials, labour, prep work, plasterboard installation, decorative pieces and any flat rate items. This makes it easier to compare plastering prices.
• Clarity On Costs And Timeline
• Ask whether the quote is a fixed price or estimate, how long the plastering work will take, and when the final coat will be ready for painting.

Providing clear information about the number of rooms, access, whether you are keeping or replacing existing plaster and what you want the result to look like helps plasterers give an accurate quote from the start.

Plastering Cost FAQs

How Much Does Plastering Cost On Average?

The average cost of plastering is usually $20 to $90 per square metre across Australia. Standard plasterboard and drywall work sits toward the lower end, while wet plaster, ceilings and decorative work are more expensive. Always treat this as a guide and use Trade Heroes to get real quotes for your home.

How Much Does It Cost To Plaster A Room?

Plastering a small room that includes walls only often costs $300 to $500, a medium room might be $900 to $1,500 and a large room can cost $1,500 to $2,500 or more. If you plaster the entire room including ceilings and features, the final price will be higher, but combining work can save money on labour.

How Much Does Ceiling Plastering Cost?

Ceiling plastering is usually more expensive than wall work and typically ranges from $25 to $35 per square metre. Small ceilings can start around $380, while large or high ceilings can reach $2,800 or more, especially when there are cornices, bulkheads or ceiling roses included.

Is Plastering More Expensive Than Painting?

Yes, plastering is more expensive because you are paying to rebuild and smooth the surface, not just change the colour. Painting alone will not fix cracks, bumps or rough bases. Quality plastering gives you a strong, even surface so future paint jobs look better and last longer.
