What Affects the Cost
Number of rooms. A standard 3x4m bedroom repaint runs $500–$900 (walls only) or $900–$1,400 (walls, ceiling, and trim). A full 3-bedroom house interior runs $4,000–$8,000. Per-square-metre rates: $25–$35/m2 for walls in good condition, $35–$45/m2 for heavy prep.
Wall condition. Old plaster walls with cracks, water stains, or peeling paint need significantly more prep than clean plasterboard. Water-stained areas need a stain-blocking primer like Zinsser B-I-N (~$120 for 3.78L) before topcoating.
Ceiling height. Standard 2.4m ceilings are simple. High ceilings in Victorian terraces (3m+) or warehouse conversions (4m+) require scaffolding or baker's scaffolds, which adds $100–$300 per room in hire costs.
Colour change. Moving from a dark feature wall to white takes 3–4 coats instead of 2. Each extra coat adds roughly $3–$5/m2 in labour and paint.
Trim and woodwork. Skirting boards, architraves, and door frames are time-consuming brush work. Including trim adds 30–40% to a room's cost. Trim requires a separate enamel paint ($28–$35/L) applied with a brush, not rolled.
Apartment access. Inner-city apartments may have lift restrictions, limited parking for the painter's van, or strata rules restricting work hours to business days.
A single bedroom repaint with clean plasterboard walls and standard ceilings sits toward $400. A full interior repaint of a 3-bedroom terrace in Paddington with high ceilings, ornate cornices, colour changes across rooms, and full trim sits toward $1,600.
Sydney-Specific Considerations
Victorian terraces (Paddington, Newtown, Balmain, Glebe). These properties have ornate plaster cornices, ceiling roses, and high ceilings (3m+) that require careful cutting-in and often scaffolding. The plaster walls are typically in worse condition than modern plasterboard, with hairline cracks and old repairs that need attention. Some have over a century of paint built up in layers. Cutting in around decorative plasterwork adds 30–50% to the cost of a room compared to flat plasterboard. If the home has wallpaper (common in Federation-era terraces in Balmain and Rozelle), removing it often reveals damaged plaster, uneven patches, and residual glue underneath. Skim coating ($25–$40/m2) is usually needed after wallpaper removal to create a smooth, paintable surface.
Heritage conservation areas. Properties in heritage conservation areas under the Sydney LEP 2012 may face restrictions on exterior paint colours. The City of Sydney publishes period-specific palettes: Victorian era (1840–1890) uses Biscuit, Deep Stone, and Sandstone with Mushroom or Teal accents; Federation/Edwardian (1890–1915) uses Pale Ochre, Burnt Pink, and Crystal Green with Deep Bronze Green trim. Haberfield's Federation streetscape (Inner West Council) has particularly strict colour controls. Interior colours are generally unrestricted.
Inner-city apartments (Surry Hills, Darlinghurst, Potts Point). Strata buildings often have colour restrictions for surfaces visible from corridors or common areas. Check your by-laws before committing to a bold scheme. Interior walls are usually unrestricted under NSW strata law (cosmetic work exemption). Access can be tight: small lifts, no goods lift, and limited street parking for the painter's equipment. Modern apartments (Green Square, Zetland, Mascot) with flat plasterboard and standard ceilings are the most cost-effective interior painting jobs in Sydney.
Warehouse conversions (Alexandria, Marrickville, Chippendale). A living area with 4-metre ceilings and exposed brick needs proper scaffolding ($150–$300/day hire) rather than step ladders. If exposed brick only needs feature sections painted, flag that clearly in the scope to avoid being quoted for the entire wall.
Lead paint. Any Sydney home built before 1970 likely has lead paint under current layers. Pre-1950 homes in the inner west, North Shore, and Eastern Suburbs may have paint with up to 50% lead by weight. DIY test kits cost $10–$15 from Bunnings, but professional XRF testing ($550–$850 for a 3-bedroom home) is more reliable. Under AS/NZS 4361.2:2017, lead paint must never be dry-sanded or dry-scraped. If the existing lead paint is intact, painting over it with a bonding primer is the safest approach.
Hiring a Licensed Painter in NSW
In NSW, painting work over $5,000 (including GST and materials) requires a contractor licence from NSW Fair Trading. There are two licence types: an Individual Contractor Licence (allows contracting and advertising) and a Qualified Supervisor Certificate (allows doing the work under a licence holder). The qualification is CPC30620 Certificate III in Painting and Decorating. You can verify any licence through the Service NSW licence check.
What to check before hiring:
Current NSW painting contractor licence (mandatory for jobs over $5,000)
Public liability insurance ($5–$20 million is standard)
A written quote that specifies number of coats, paint brand and finish, and what prep is included
References or recent project photos
Worth checking: no written quote, vague on paint brand ("we use good paint"), unwilling to show their licence, or quoting without inspecting the property first. A painter who quotes over the phone without seeing the walls is guessing.
How We Calculate
Estimates are based on current licensed Painter rates in the Sydney metro area, adjusted for property age and typical housing stock. All prices include GST. Figures cover standard residential interior painting including walls, ceilings, and basic prep. Specialty finishes, wallpaper removal, and lead paint remediation are not included.
