Interior Painting Cost Guide (2026)

Fresh paint is the highest-return, lowest-cost way to transform a home — but quotes vary wildly because most of the work you’re paying for is invisible once it’s done: prep, priming, and clean lines. Understanding what drives the price helps you tell a thorough pro from a cheap-and-fast one.

Here’s what interior painting costs in 2026 and how to read a painting quote so you compare bids fairly.

2026 painting costs at a glance

Professional interior painting typically runs AA$55–AA$160 per m² of floor area, or by the room:

• Average bedroom (10×12): A$540–A$1,200.
• Living room or larger space: A$930–A$2,300.
• Whole interior of a ~185 m² home: A$6,200–A$17,000.
• Trim, doors and ceilings: often priced separately — ceilings add ~40% to a room.
• Add-ons: accent walls, high ceilings, wallpaper removal, and heavy patching all cost extra.

What drives the price

Two painters can bid the same room 2× apart because of these:

• Prep work — patching, sanding, caulking and priming is where quality (and hours) live.
• Wall condition — cracks, water stains and old wallpaper add significant labour.
• Number of colours and finishes — more cut-ins and more coats.
• Ceiling height and trim detail — crown molding, wainscoting and stairwells slow things down.
• Paint grade — premium paint costs more per gallon but covers better and lasts longer.

How to compare painting quotes

A good quote makes the invisible work explicit. Look for:

1. Exactly which surfaces are included (walls only? trim? ceilings? closets?).
2. Number of coats and whether primer is included.
3. The specific paint brand, line, and finish — not just "good paint."
4. Prep scope — patching, caulking, sanding, and how nail holes and cracks are handled.
5. Protection and cleanup — covering floors and furniture, and a defined finish standard.

What’s different in Australia

Prices on this page are in Australian dollars and reflect typical national ranges; your state and city matter a lot. Sydney, Melbourne, Canberra and remote/regional areas sit at the higher end, and northern zones add cyclone and heat considerations.

By law, electrical and plumbing work must be carried out by a licensed tradesperson — unlicensed DIY on these is illegal and voids insurance. Most building work follows the National Construction Code and relevant Australian Standards, needs council/private-certifier approval, and attracts 10% GST. In homes built before the late 1980s, assume asbestos may be present and test before disturbing materials.
