Where the facts come from
Rules come from the regulators and the law itself: QBCC, Consumer Affairs Victoria, Energy Safe Victoria, Building and Energy in WA, the NSW Government, Access Canberra, and the state and territory legislation websites.
Building code facts come from the Australian Building Codes Board. Storm and cyclone facts come from the Cyclone Testing Station and government disaster reports, and door and opener facts come from the makers' own pages and owner manuals.
Each fact is stored with the page it came from and the date it was read. A page that uses the fact lists that source at the bottom, so you can open the original.
How we write
- A maker's figure stays the maker's. Headroom, side room and warranty figures are given as Steel-Line's or B&D's, never as a general rule.
- A rule appears only on pages for the state it belongs to, with the state named.
- Springs, cables and roller door tension are always jobs to leave alone, in the makers' own words.
- No prices, cost ranges or rates. The dollar figures on this site are legal thresholds, such as the $3,300 line for a QBCC licence in Queensland.
- No made-up jobs, customers or reviews.
- Some photos here are illustrations made with an AI image tool. None shows a real job or a business in our network.
- Every number on a page has to match a number in our fact base, and an automated check stops the page going up if one does not.
What stays off the site
If a source cannot be read, the fact waits. Several South Australian and Northern Territory government sites could not be read when these pages were written, so those state pages keep to what other official sources confirm and give no figure we could not check.
Australian Standards such as AS/NZS 4505 sit behind a paywall, so pages don't quote clause figures from them. Where a test matters, such as checking that an opener reverses, the page gives the maker's own steps and says whose they are.
Queensland's Household Resilience Program closed to new applications on 2 October 2026, so it is only ever mentioned as closed.
Who writes and checks
The Door Hero team writes the pages and checks each one against its sources before it goes up. The Door Hero does not do door work, so the pages lean on what regulators and makers publish rather than on anyone's opinion.
Corrections and changes
When a rule changes or a mistake turns up, the page is corrected against its source and the updated date at the top moves with it.
Where a law starts on a set date, the page names the date and the state. NCC 2025, for example, applies in Queensland from 1 May 2027, so a Queensland page says exactly that.
