Plastering is a critical part of finishing a home or renovation project, providing smooth surfaces for walls and ceilings while offering insulation and fire resistance. Whether you’re building a new home or updating an existing space, one of the most important factors to consider is the cost of plastering.
In Australia, plastering costs can vary significantly depending on the type of plaster, the size of the area to be plastered, the quality of materials used, and the complexity of the job.

Types Of Plastering
Before delving into the costs, it’s essential to understand the different types of plastering services that may be required. In Australia, you might encounter several plastering techniques, each with its unique characteristics, uses, and pricing.
Traditional Plastering (Lime And Gypsum Plaster)
This is the most common form of plastering, especially in older homes or renovations. It involves applying a base coat followed by one or more finishing coats. Lime-based plaster is known for its breathability and flexibility, while gypsum-based plaster is quicker to dry and easier to work with.
Drywall Or Gyprock (Plasterboard)
Gyprock is a popular material used for interior walls and ceilings in Australian homes. It is a pre-fabricated plasterboard that is installed over timber or steel studs. Gyprock is often used for its ease of installation and cost-effectiveness, particularly in new builds.
Rendering (External Plastering)
Rendering is the application of a thin coat of plaster to external walls, often for aesthetic purposes or to improve the appearance of the building. This technique is typically used with cement-based render or acrylic render for more durability and weather resistance.
Cornices And Mouldings
For added style, many homeowners opt for decorative cornices and plaster mouldings, particularly in period-style homes. Cornices are applied where the ceiling meets the wall, creating a smooth and often ornate finish.
Factors Affecting The Cost Of Plastering
The cost of plastering a house depends on several variables. Below are the key factors that will influence your final price.
Size Of The Area To Be Plastered
The size of the area you need to plaster is the most significant determinant of cost. Plastering is typically charged by the square metre, and the larger the surface area, the more expensive the job. Plastering an entire house (walls and ceilings) can add up quickly, so if you’re renovating or building a larger home, the costs will be proportionally higher.
For example:
- A small room (10–20 square metres) might cost anywhere between $600 to $1,500 to plaster.
- A medium-sized room (20–40 square metres) could range from $1,500 to $2,500.
- Plastering the entire house, particularly a standard four-bedroom house, could cost anywhere from $5,000 to $15,000 or more, depending on the total surface area.
Plaster Type And Quality
The type of plaster you choose will have a direct impact on the price. Traditional plastering using gypsum or lime plasters will generally be more expensive than installing drywall (Gyprock). Additionally, premium materials or specialty finishes, such as Venetian plaster (a high-end, polished plaster), will cost significantly more.
Here are the approximate costs for some common types of plaster:
- Gyprock (Drywall): Around $30–$50 per square metre.
- Traditional Plastering: Can range from $50–$75 per square metre, depending on the finish.
- Rendering (Exterior Plastering): Typically between $40–$80 per square metre for a basic render, with textured finishes or acrylic renders costing more.
Labour Costs
Labour costs in Australia vary depending on the region and the complexity of the job. A professional plasterer usually charges an hourly rate or a rate per square metre. The hourly rate for plasterers typically falls between $40 and $80 per hour, but this can increase if the job requires additional skills or if you’re hiring a specialist.
Keep in mind that plastering is a labour-intensive task. For a standard job, plastering can take anywhere from 1 to 3 days depending on the size of the area and the type of plaster used. This means that the cost of labour can quickly add up, especially if the job takes longer than expected.
Accessibility And Site Conditions
The ease of access to the area that needs plastering can also influence the cost. If the space is difficult to reach (such as in high ceilings, narrow spaces, or multi-storey homes), additional scaffolding or equipment may be needed, which could increase the cost of the job. Similarly, if there are pre-existing issues like damaged or uneven walls that require extra preparation, this will add to the cost.
Finishing Touches
Additional features, such as decorative cornices, architraves, or intricate moulding, will also increase the cost. Basic cornices might cost between $5 to $10 per metre, while more detailed, customised designs can push the price up to $20 or more per metre.
Location
The location of your property plays a role in plastering costs. Generally, labour and materials tend to be more expensive in major cities like Sydney, Melbourne, and Brisbane due to the higher cost of living and demand for services. If you live in a rural or remote area, you may also incur additional costs for travel and transportation of materials.
Plastering Costs For Common Projects
To give you a clearer idea of what you can expect to pay for different plastering jobs, here are some rough estimates based on common projects:
Plastering A Room
- Small room (10-15 square metres): $600–$1,200
- Medium room (15–30 square metres): $1,200–$2,500
- Large room (30+ square metres): $2,500–$4,000
Plastering An Entire House
- Two-bedroom home: $5,000–$10,000
- Three-bedroom home: $7,000–$12,000
- Four-bedroom home: $10,000–$15,000
- Luxury home with premium finishes: $20,000+
Ceiling Plastering
- If you’re only plastering ceilings, expect costs to range from $30 to $50 per square metre, depending on the height of the ceiling and the finish.
Rendering The Exterior Of A House
- Basic rendering for a standard-sized home: $40–$60 per square metre.
- High-quality acrylic or textured render: $60–$80 per square metre.
How To Save On Plastering Costs
Plastering can be a significant expense in a renovation or building project, but there are several ways to reduce costs without compromising on quality.
Choose Cost-Effective Materials
- Opt for standard Gyprock or plasterboard rather than more expensive options like Venetian plaster or specialty finishes.
Diy Preparation
- While plastering is best left to the professionals, you can help reduce costs by preparing the walls beforehand. For example, clearing the area, removing old wallpaper, or sanding rough patches can save time and reduce labour costs.
Get Multiple Quotes
- Always get at least three quotes from different plasterers to ensure you’re getting a competitive price. Don’t just go for the cheapest option; make sure the plasterer has good reviews and a solid track record.
Consider Phased Work
- If you’re renovating or building a home in stages, consider plastering areas as they’re completed rather than all at once. This way, you can spread out costs and ensure you’re only paying for plastering when the space is ready.
Conclusion
Plastering is an essential part of completing a home build or renovation, and understanding the costs involved will help you plan and budget effectively. Prices in Australia can vary significantly based on the size of the area, the materials used, and the complexity of the job. For a standard four-bedroom home, you might expect plastering costs to range from $5,000 to $15,000, but this can increase or decrease depending on various factors.
To get the best value for your money, ensure you research materials, get multiple quotes, and carefully consider the type of plastering that fits both your aesthetic preferences and budget. Plastering is an investment in the beauty, functionality, and longevity of your home, so it’s worth considering all your options before making a final decision.
Frequently Ask Question
Can I Plaster My House Myself?
While plastering is a skilful and labour-intensive job, some homeowners may opt for DIY plasterboard installation, especially in new builds. However, traditional plastering and rendering require professional expertise for a high-quality finish. Improper plastering can lead to cracks, uneven surfaces, and durability issues, so it’s best to hire a skilled plasterer for these tasks.
Is It Worth Investing In High-End Plaster Finishes?
High-end plaster finishes, like Venetian plaster, provide a polished, luxurious look and enhanced durability, but they come with a higher price tag. If you’re looking to create a specific aesthetic or are renovating a period-style home, investing in these finishes might be worth it. However, for budget-conscious projects, standard Gyprock or traditional plaster may offer a similar functional finish at a lower cost.
How Can I Save Money On Plastering?
To save on plastering costs, consider choosing more affordable materials like Gyprock instead of premium finishes like Venetian plaster. Doing some of the prep work yourself, such as clearing the area and sanding rough surfaces, can also reduce labour costs. Additionally, getting multiple quotes from different plasterers ensures you get the best value for your budget.
