How much does house painting cost in Australia?
Professional house painting in Australia typically costs from about $20 per square metre of floor area for interior walls only, up to $105 per square metre for a full interior-and-exterior repaint. Prep work, ceiling height, the number of coats and the condition of existing surfaces all move the price.
Painting cost by job type
| Job | Cost per m² of floor area |
|---|---|
| Interior — walls only | $20–$35 |
| Interior — walls, ceilings & trim | $30–$50 |
| Exterior — full house | $35–$65 |
| Whole house — interior & exterior | $60–$105 |
What affects your painting cost?
- Surface condition — peeling paint, cracks and patching add significant prep time, which is mostly labour.
- Number of coats — dark-to-light colour changes or bare surfaces often need an extra coat.
- Ceiling height and access — high ceilings, stairwells and multi-storey exteriors need scaffolding and slow the job.
- Trim and detail — doors, skirting, architraves and windows are fiddly and charged accordingly.
- Paint quality — premium washable and exterior-grade paints cost more but last longer.
- Location — painter day rates are higher in the major capitals.
Frequently asked questions
How accurate is this painting cost calculator?
It gives an indicative range based on floor area and current Australian painter rates. Painters quote by surface area, room or day rate, so get an on-site quote for an exact figure.
Is it cheaper to paint a house yourself?
DIY saves on labour, which is most of the cost, but professional prep and finish last longer and are far safer for high or exterior work.
How much does it cost to paint a 3-bedroom house interior?
For a typical 150 m² home, interior walls, ceilings and trim run roughly $4,500–$7,500 in good condition, more if heavy prep is needed.
How often should I repaint?
Interiors typically last 7–10 years and exteriors 5–10 years, depending on paint quality, sun exposure and surface condition.
How many coats of paint are included?
Professional quotes usually allow two coats over a prepared surface, plus a primer or sealer on bare or patched areas. Dark-to-light colour changes, strong feature walls and new plasterboard often need an extra coat, which adds to both paint and labour.
Painting cost by home size
As a rough guide using floor area, a small unit around 70 m² costs roughly $1,400–$2,450 for interior walls only, a typical 150 m² three-bedroom home runs about $4,500–$7,500 for walls, ceilings and trim, and a large 250 m² home can reach $15,000–$26,000 for a full interior-and-exterior repaint in good condition. Heavy preparation, high ceilings and difficult access push these figures higher, which is why the calculator includes a condition and access adjustment. Getting two or three written quotes is the best way to confirm your exact painting cost.
