Question 1

How much does it cost to paint the interior of a house in Australia?

Accepted Answer

hipages' 2026 guide puts a full interior repaint at roughly $60–$100 per square metre of floor area, so a small single-storey home (about 100 m² of floor) lands near $6,000–$10,000 GST inclusive, with larger homes running well above. Use the calculator above for a range matched to your paintable wall area, coats, prep level, and paint grade.

Question 2

Does the estimate include ceilings and trim?

Accepted Answer

Yes — toggle 'Include ceilings' and 'Include trim & doors' to add or remove those surfaces. Ceilings are estimated at roughly 35% of your paintable wall area, and trim, doors and window frames at 15%. Prices shown are GST inclusive.

Question 3

How does paint grade affect the cost?

Accepted Answer

Budget paint lowers the estimate by about 15%; premium paint raises it by about 35%. Mid-grade water-based paint ($30–$45 per litre in Australia) is the baseline. Higher-grade paints often cover better and wear longer, stretching the time between repaints.
