What Affects the Cost
Masonry lining. Adelaide's older homes are frequently solid masonry construction without timber framing. Lining these walls with plasterboard requires furring channels (metal channels fixed into the masonry with concrete screws or Dynabolts) before the board can be hung. This adds $8–$15/m2 for the channel installation on top of the standard boarding rate.
Fire-rated requirements. Multi-dwelling developments (townhouses, units) require fire-rated assemblies between attached dwellings under the
NCC. This means specific board types such as
CSR Gyprock Fyrchek or
Knauf Firestop ($35–$45/sheet) and specific installation methods, adding $10–$20/m2 over standard board.
Ceiling lining. Ceiling work costs 30–50% more than walls. Older Adelaide homes with high ceilings (3m+ in some character homes) increase the difficulty, requiring longer sheets and internal scaffolding.
Total area. Larger jobs reduce the per-square-metre rate. A full renovation across multiple rooms is more cost-effective than a single wall, which carries a minimum charge.
Board type. Standard 10mm ($12–$18/sheet) or 13mm ($16–$24/sheet) is the baseline. Moisture-resistant board ($22–$32/sheet) for bathrooms, fire-rated for party walls and garage separations.
Finish level. Level 4 is standard residential. Level 5 (full skim coat, $5–$10/m2 extra) adds a flawless finish relevant for feature walls or open-plan living areas with LED
downlighting.
A single partition wall in a modern home at Mawson Lakes with standard board and cove cornice sits toward $700. A full renovation in a character home with masonry lining, high ceilings, fire-rated party walls, and Level 5 finishing pushes toward $7,000.
Adelaide-Specific Considerations
Adelaide's character home suburbs present the most distinctive plasterboard challenge in the city. In Norwood, Unley, Prospect, North Adelaide, Goodwood, and Colonel Light Gardens, a large proportion of homes are bluestone or sandstone construction with solid walls and no cavity. Lining these walls with plasterboard requires furring channels fixed into the masonry, creating a gap for insulation and a flat surface for the board.
This is not complex work, but it does add a step (and cost) that modern framed construction does not require. The trade-off is worthwhile: the gap behind the plasterboard can be filled with insulation batts, improving both thermal and acoustic performance of the solid masonry walls. For Adelaide's hot summers and cold winters, this is one of the most cost-effective comfort upgrades available during a renovation. The insulation effectively pays for itself through reduced heating and air conditioning costs within a few years.
In newer suburbs across Mawson Lakes, Seaford, and Munno Para, construction is standard timber or steel framing with plasterboard at 2.4m ceiling height. This is straightforward work with predictable pricing, and the three major manufacturers (CSR Gyprock, Knauf, and Siniat) all supply through Adelaide trade outlets.
Multi-dwelling developments across Adelaide's infill corridors, particularly along Prospect Road, Unley Road, and Henley Beach Road, require fire-rated party walls between attached dwellings. Adelaide's building surveyors enforce NCC compliance on these assemblies, typically FRL 60/60/60 for inter-tenancy walls. Using the correct fire-rated board (pink-faced paper, denser core) in the correct layering with rated compounds is not optional.
Adelaide has a smaller trade pool than Melbourne or Sydney. During busy periods, plasterer availability can be tighter and lead times longer. For planned renovation work, booking three to four weeks ahead is advisable.
Hiring a Licensed Plasterer in SA
In South Australia, Consumer and Business Services (CBS) administers building work contractor licences. Plastering work that constitutes building work requires a Building Work Contractor's Licence. You can verify a plasterer's licence on the CBS licence search.
A good plasterer will:
Hold trade qualifications (Cert III in Wall and Ceiling Lining, CPC31920, or equivalent)
Provide their current licence number upfront
Confirm experience with your specific wall type (framed vs masonry lining)
Specify board type, finish level, and inclusions in a written quote
Explain their dust management approach, particularly for renovation work in occupied homes
Worth checking:
For character home renovations involving furring channels on masonry, whether the plasterer handles the channel installation or whether a separate framer is needed
The quote separates masonry preparation, boarding, finishing, and cornice costs
For fire-rated work, they can show you the specific system being installed and confirm it meets the FRL specified by your building surveyor
Public liability insurance is current
They confirm coordination with
electricians and plumbers for rough-in before boarding
How We Calculate
Estimates are based on current plasterer rates in the Adelaide metropolitan area, adjusted for property age and typical wall construction in SA. All prices include GST. Figures cover plasterboard supply, fix, and finish. Framing, insulation, electrical rough-in, and painting are excluded unless noted.
