Interior Painting Cost Per Square Metre in Australia (2025)
When budgeting for interior painting, one of the most common questions is: what does it actually cost per square metre? In Australia in 2025, interior painting costs vary based on room type, surface condition, paint quality, and whether ceilings and trims are included. This guide breaks down typical rates so you can budget confidently.
Interior Wall Painting: Cost Per Square Metre
Interior wall painting in Australia typically costs $25–$55 per square metre for labour and materials, assuming standard preparation on good-condition surfaces. This usually includes one coat of primer (if required) plus two coats of a quality low-sheen wall paint.
Premium finishes (such as Dulux Wash & Wear or Taubmans Endure) sit at the higher end of this range. Budget paint systems using cheaper products may start around $18–$25 per m² but often require more coats and may not last as long.
For context: a standard 4m x 4m bedroom has approximately 32 m² of wall area (allowing for doors and windows). At $35/m², that's roughly $1,120 — though most painters quote per room rather than strictly per m².
Ceiling Painting: Cost Per Square Metre
Ceiling painting typically costs $15–$30 per square metre in Australia. Ceilings are faster to paint than walls (less cutting in around obstacles) but can be more physically demanding, which is reflected in the rate.
A standard 4m x 4m bedroom ceiling (16 m²) would typically cost $240–$480 to paint, including a quality ceiling white. High or ornate ceilings may attract a premium.
Trim, Skirtings, and Architraves: Pricing
Trim painting (skirtings, architraves, cornices, and door frames) is typically quoted as a fixed rate per lineal metre or per item. Skirting boards typically cost $3–$8 per lineal metre, while doors cost $80–$150 per door depending on style and whether both sides are included.
Including trim painting significantly adds to the overall cost of a room repaint but makes an enormous difference to the quality of the finished result. Glossy white trims against freshly painted walls transform a room.
Room-by-Room Interior Painting Estimates
Bedroom (standard): $400–$750 including walls and ceiling, two coats. Trim extra.
Living/dining room (large open plan): $800–$2,000 depending on size and ceiling height.
Kitchen: $300–$700 for walls — often requires higher-sheen paint for washability.
Bathroom: $300–$600 — humidity-resistant paint required.
Hallway and staircase: $500–$1,500 depending on length and ceiling height.
Full 4-bedroom house interior repaint: $4,500–$12,000+ including all rooms, ceilings, and trims.
