How this calculator is built
Unit costs with sources
This model cites 2 sources for its line-item cost and regional labour inputs.
Regional labour adjustment
The state table applies local labour indexes only to labour-heavy line items.
Published methodology
The methodology page lists the formula, size drivers, labour model, and source links.
How this estimate is calculated
The model prices 5 project line items from published cost inputs. Quantities are driven by the number of doors, the door size, the door type, and whether an automatic opener is added or the old door removed. The selected scope and finish adjust those inputs, then the regional index changes only each line's labour share; material prices remain national.
The itemised midpoint is shown as a ±25% planning range. It is not a contractor quote: access, design choices, permits, availability, and site conditions can move the final price.

Common questions
How much does it cost to replace a garage door in Australia?
A single door installed typically runs about $1,600–$4,800, with a mid-grade insulated sectional near $2,200 GST inclusive without a motor — the calculator's default. Powered roller singles run $1,200–$3,000 fitted and sectionals $1,800–$3,800, while premium and double doors cost more. Prices shown are GST inclusive.
Should I add an automatic opener?
A motorised opener with remote control, fitted, typically adds around $400–$700 to a single door and is what turns a manual door into an automatic one. Toggle 'New automatic opener' to include it; leave it off if you are keeping a manual door or reusing an existing motor.
Do I need cyclone-rated or bushfire-rated doors?
In the tropical cyclone regions of northern Queensland, the Northern Territory, and coastal WA, garage doors must use cyclone-rated fixings and wind-load-tested panels under the building code. In designated bushfire-prone areas — extensive across Victoria, NSW, SA and the ACT fringe — a BAL rating can require ember-resistant seals and non-combustible panels. Both are specification upgrades that lift the price above the calculator's baseline.
