For early planning, repainting the interior of an occupied Australian house commonly needs a budget in the broad order of $6,000–$15,000 for a compact home, $10,000–$25,000 for a typical three-bedroom home, and $16,000–$40,000 or more for a larger or heavily detailed home. These are indicative Aurenoo planning bands, not a national price list. A sound, empty house with standard-height walls can fall below them; extensive repairs, high ceilings, many doors and trims, difficult access or premium systems can move well above them.
The most reliable way to estimate interior painting is to price the actual surfaces and preparation rather than multiply bedroom count by a single rate. Define whether “whole interior” includes walls, ceilings, skirtings, architraves, doors, window frames, wardrobes and wet areas. Then add access, protection, repairs, colour changes, coats, GST and any temporary accommodation or furniture-moving costs.
Use the planning bands as a starting point
| Illustrative scope | Planning allowance | Typical assumptions |
|---|---|---|
| Single standard room | $700–$1,800 | Walls and ceiling, modest trim, limited repairs |
| Two-bedroom compact home | $6,000–$15,000 | Standard heights, ordinary preparation |
| Three-bedroom home | $10,000–$25,000 | Walls, ceilings and a normal amount of trim |
| Four-bedroom or larger home | $16,000–$40,000+ | More circulation, doors, detail and access |
The bands assume a professional repaint of previously coated surfaces in serviceable condition. They do not automatically include major plaster replacement, active leak repairs, asbestos or lead management, specialist decorative finishes, elaborate joinery, exterior work or structural cracking. Regional labour availability and travel can also change the result.
Room count is useful for a quick sense check, but floor area alone is imperfect. A 140 m² open-plan home can have less wall area than a smaller home divided into many rooms. A house with 3.3 m ceilings contains more paintable wall than an identical floor plan with 2.4 m ceilings. Measure enough detail to explain the difference.
Separate the surfaces included in the quote
“Paint the interior” can mean walls only or every visible coated surface. Ask for a schedule that lists each surface and coating system. This makes quotes comparable and prevents a cheap headline from becoming a series of variations.
- Walls: measure perimeter by height, then allow for openings according to the estimator’s method.
- Ceilings: generally track floor area, with additions for raked forms, bulkheads and voids.
- Skirtings and architraves: priced by lineal extent, profile and condition.
- Doors and frames: identify faces, edges, jambs and whether hardware is removed.
- Windows: distinguish simple reveals from detailed timber sashes.
- Joinery and wardrobes: include only when the substrate and coating are suitable.
Ceilings are not merely another horizontal wall. They require overhead work, careful protection and consistent application across broad areas. Patchiness is especially visible under grazing light. Tall stairwells, double-height entries and raked ceilings may require scaffold or another access solution, adding setup time and safety controls.
Doors can be a substantial subproject. A house with twelve internal doors has at least twenty-four broad faces before edges and frames are considered. Changing dark enamel to a pale colour, repairing chips, removing failing layers or achieving a fine finish can take more labour than their area suggests.
Preparation often determines the price
On a straightforward repaint, preparation may involve washing, minor filling, light sanding where safe, spot priming, masking and protection. On a neglected interior it can include stabilising peeling coatings, repairing plaster, treating stains after their source is fixed, filling extensive settlement cracks and restoring damaged trim. Quotes should state how much preparation is included and how unforeseen work is handled.
A low square-metre rate usually assumes a predictable substrate. It cannot sensibly cover unknown water damage or widespread adhesion failure. If the home has recurring cracks, bubbling, damp or mould, investigate the cause before painting. Otherwise money is spent on a finish that may fail again.
Older homes need a safety decision before abrasive preparation. Lead may be present in older paint, while some linings, textured coatings or backing products may contain asbestos. The Australian Government’s asbestos guidance for home renovators says suspect material cannot be confirmed safe by appearance. Do not let an allowance for “sanding throughout” become permission to disturb uncertain material without assessment and suitable controls.
A condition schedule improves quote accuracy
Walk through each room and rate walls, ceiling and trim as sound, minor repair, moderate repair or specialist assessment. Photograph representative defects and give the same schedule to every tenderer. If one painter includes two days of repair and another includes only a few hours, the price difference becomes understandable.
Coats and colour changes affect labour as well as paint
The required system depends on the substrate, existing coating, new colour and performance expectation. A similar-colour repaint on a sealed wall may be simpler than covering a saturated colour with white. Fresh filler or bare plasterboard areas may need a compatible sealer; stains may require a specialist product after the underlying issue is resolved.
Manufacturer information demonstrates why “primer included” is too vague. The Dulux 1Step Prep product guidance, for example, lists intended interior and exterior surfaces and functions such as sealing and stain blocking. It does not mean that product is correct for every stain or substrate. Ask the supplier or painter to identify the precise preparation product and confirm compatibility with the topcoat.
A related guide to consider while planning this work is How Much Does It Cost to Paint a House Exterior?.
Do not make a universal assumption that every job needs exactly one primer and two topcoats. Ask the painter to nominate the intended system and the standard for acceptable hiding. Product coverage figures are theoretical planning inputs and can be reduced by texture, porosity and application losses. Drying and recoat intervals must follow the selected product’s technical instructions and site conditions.
Colour complexity matters. One wall colour throughout is quicker to organise than multiple feature colours, sharply contrasting trims and several ceiling whites. Every transition requires cutting in, tool management and cleaning. If the design is still unsettled, use the whole-home colour selection process before painters price the work.
Labour is more than time spent rolling
Professional pricing covers setup, protection, preparation, application, movement between rooms, drying-dependent return visits, cleaning and business overheads. Labour can form the majority of a repaint where the paintable area is detailed or damaged. The general renovation labour cost guide explains why charge-out rates cannot be compared directly with a worker’s wage.
Occupied homes usually take longer. Furniture must be shifted and protected, rooms may be released in stages, pets and children need separation, and the team may lose efficient access. An empty home with power, water, clear floors and uninterrupted rooms is easier to sequence. If you plan to remain in residence, agree which room stays usable and whether contents-moving is included.
Travel and parking can also matter. A metropolitan apartment with loading restrictions, lift bookings and limited material storage may cost more to service than its floor area suggests. A regional home may involve travel or accommodation. These are legitimate project inputs and should be explicit rather than buried in a vague lump sum.
Build an estimate from quantities
A useful pre-quote model assigns a rate or allowance to groups of surfaces, then adds preparation and access. The numbers below are a hypothetical example only; they demonstrate arithmetic, not a recommended contractor rate.
Suppose a three-bedroom home has 360 m² of net wall and ceiling area. If an early blended labour-and-material allowance for standard surfaces is $28–$45 per m², that component is $10,080–$16,200. Add $1,200–$2,800 for twelve doors and frames, $1,000–$2,500 for more detailed trim, and $800–$2,000 for minor repairs and occupied-home protection. The resulting planning range is $13,080–$23,500 before unusual access or specialist work.
This model is deliberately transparent: replace every quantity and allowance with information from your home. Do not take $28–$45 as a published national average. Local painters may quote by room, day, surface area or lump sum, and the same business may use different methods for different scopes.
Allow for GST, exclusions and contingency
Confirm whether every figure includes GST. For a business registered for GST, an ambiguous ex-GST quote creates a 10% difference at the invoice stage. Also clarify disposal, consumables, colour consultation, sample areas, furniture moving, hardware removal, final cleaning and small return visits.
A contingency should cover unresolved scope rather than hide an incomplete brief. A sound, inspected repaint may need a modest reserve; a house with uncertain coatings, moisture history or extensive cracking requires more investigation and potentially a larger allowance. The renovation contingency guide helps match the reserve to uncertainty.
Common exclusions include:
- repairing the source of water ingress or mould;
- removing or managing hazardous materials;
- major plaster, carpentry or glazing repairs;
- painting inside cupboards and wardrobes;
- specialist two-pack, limewash or decorative finishes;
- scaffold, elevated work platforms or unusual access;
- moving unusually heavy or fragile contents.
Compare quotes on scope, not just total price
Provide each painter with the same rooms, surfaces, colours and condition notes. Ask for the product range, sheen, preparation, coat system, repair allowance, exclusions, programme, access method and warranty terms. Check applicable registrations or licences with the relevant state or territory regulator where required; requirements vary by jurisdiction and contract value.
Our guide to comparing renovation quotes provides a line-by-line method. For painting, pay particular attention to vague phrases such as “prepare as necessary” and “two coats where required”. Ask what observable work and finish those phrases buy.
A deposit and progress schedule should correspond with the job’s size and local legal requirements. Do not pay the full amount merely to secure a date. Record approved changes in writing, including extra preparation discovered after furniture is moved or coatings are tested.
DIY changes the cash cost, not the amount of work
A homeowner doing safe, suitable work may reduce paid labour but must budget for paint, primers, filler, abrasives, masking, floor protection, tools, access equipment, disposal and mistakes. Time has value too. A first-time painter may occupy rooms for several weekends and use more material while learning.
Keep hazardous or high-access work outside a casual DIY plan. Do not sand suspect old coatings or use improvised ladders in stair voids. If the substrate is modern, sound and accessible, the technique in painting walls without streaks can help plan an ordinary wall repaint safely.
Control cost before the first room is painted
Finalise colours and sheen, repair leaks, clear rooms, identify surfaces, and decide whether hardware remains or is replaced. Stage the work logically so completed rooms are not damaged by later trades. Painting before dusty demolition or major flooring preparation can create avoidable rework.
When the budget is tight, prioritise the most visible connected spaces and surfaces in the poorest condition. Keep the coating system appropriate; save by reducing colour changes, simplifying scope or doing safe clearing and cleaning by agreement, not by deleting essential preparation. The broader budget renovation guide applies the same principle across the house.
A credible interior painting budget is therefore a scope document with numbers attached. Use the broad bands to test affordability, then replace them with measured, comparable quotations. When walls, ceilings, trim, repairs, access, protection, GST and exclusions are all visible, the final price becomes much easier to understand and manage.
Test three scope options instead of cutting quality blindly
If the first quotation exceeds the budget, ask for separately priced options rather than reducing preparation across every room. One option might cover the full interior now. A second could complete connected living areas, entry and the most worn bedrooms. A third might paint ceilings and walls while postponing sound trim. Natural boundaries reduce visible mismatches and allow future stages to be planned.
Do not remove work that protects the substrate or manages a known hazard. Savings are more defensible when they come from fewer colours, empty rooms, retained sound doors, simpler feature treatments or coordinated access. Compare how each option changes both appearance and expected disruption.
For example, suppose the full $22,000 proposal includes $4,000 for wardrobes and low-priority utility rooms, $2,500 for changing all sound trim from dark to white, and $15,500 for the connected main interior. Deferring the first two items could create a $15,500 stage without pretending the same full scope costs less. Check whether remobilisation will make the later stage more expensive and document the stopping points.
Allow for programme and household costs
Paint price is not the only budget effect. Rooms may be unavailable, curtains and wall-mounted items need removal, and sensitive occupants may choose to stay elsewhere during parts of the work. Ask how ventilation, security and access will be managed, and follow product safety information. If flooring or electrical work is also planned, sequence it so freshly finished walls are not repeatedly damaged.
A written room-by-room programme helps the household move contents once rather than several times. It also shows whether the quote assumes simultaneous access to the whole house. Where work is staged around occupation, allow for additional setup and cleaning rather than expecting the efficiency of an empty property.
